GEOLUT COMMISSIONING
|
||
2.1
|
||
General
|
||
The Cospas-Sarsat GEOLUT commissioning requirements defined in this document are intended to be
|
||
performed in addition to national acceptance tests, and are required prior to fully integrating a
|
||
GEOLUT into the Cospas-Sarsat Ground Segment. Conducting the tests detailed in this document and
|
||
assessing the results is the responsibility of the national Administration desiring to commission the
|
||
GEOLUT.
|
||
The commissioning requirements detailed herein verify the GEOLUT's ability to receive and process
|
||
signals transmitting in the 406 MHz band in accordance with the Cospas-Sarsat GEOLUT Performance
|
||
Specification and Design Guidelines (C/S T.009). Consequently each specification detailed in
|
||
document C/S T.009 has associated commissioning requirements detailed herein. A matrix identifying
|
||
the requirements in document C/S T.009 and the corresponding sections in this document is provided
|
||
at Annex I. All tests required to commission the GEOLUT shall be conducted with the GEOLUT in
|
||
its operational configuration and location, and connected to the associated MCC. However, the data
|
||
should not be distributed to other Cospas-Sarsat Ground Segment Operators.
|
||
For multiple GEOLUT installations, each GEOLUT shall be commissioned individually and as if it
|
||
were a stand-alone GEOLUT. A GEOLUT which is capable of operating with more than one type of
|
||
GEOSAR satellite shall be commissioned separately for each type. The national Administration may
|
||
conduct the testing and submit the commissioning reports for each of the GEOLUT / type of GEOSAR
|
||
satellite combination to the Cospas-Sarsat Secretariat separately or at the same time.
|
||
2.2
|
||
Pre-Test Requirements
|
||
Prior to commencing the testing portion of the commissioning programme, the national Administration
|
||
conducting the tests shall co-ordinate with the appropriate authorities in its SAR region, as well as
|
||
notify all affected Cospas-Sarsat MCCs, of the test periods and the test beacon location(s). This
|
||
information shall also be provided to the Cospas-Sarsat Secretariat. The time and dates for performing
|
||
commissioning tests should be chosen such that the operational impact of the testing on the LEOSAR
|
||
system is minimized.
|
||
2.3
|
||
Test Data Collection
|
||
The GEOLUT commissioning process involves collecting specified numbers of error free 406 MHz
|
||
beacon messages. As test transmissions in the 406 MHz band will be detected and processed by other
|
||
LEOLUTs, GEOLUTs, and MCCs, it is desirable to complete the tests as quickly as possible in order
|
||
to reduce the volume of non-emergency messages handled by other national Administrations.
|
||
2.4
|
||
Frequency Registration
|
||
Administrations should register their use of the downlink frequency band processed by their GEOLUTs
|
||
with the International Telecommunication Union (ITU) in accordance with article 11 of the radio
|
||
regulations. The information required to notify GEOLUTs is identified at Annex H. The ITU only
|
||
|
||
2-2
|
||
|
||
accepts notification requests submitted in electronic format and has developed a software application,
|
||
available free of charge from their web site, which captures the required information and produces the
|
||
necessary electronic file. A separate GEOLUT notification should be filed with the ITU for each type
|
||
of GEOSAR satellite with which the GEOLUT operates.
|
||
2.5
|
||
Data Collection Limitation
|
||
Only the data collected from those GEOSAR satellites that comply with the document Description of
|
||
the 406 MHz Payloads Used in the Cospas-Sarsat System (C/S T.011) should be used for the statistical
|
||
data analysis. Data for GEOLUT commissioning purposes should be collected only from
|
||
commissioned GEOSAR satellites, and not from GEOSAR satellites in initial operational capability
|
||
(IOC) status.
|
||
2.6
|
||
Submission of Results
|
||
The national Administration wishing to commission a GEOLUT into the Cospas-Sarsat System, shall
|
||
submit a commissioning report (as detailed at Annex A) for a review by the Joint Committee or an
|
||
Expert Working Group (EWG) tasked by the Cospas-Sarsat Council to review LUT commissioning
|
||
reports. In addition, the data specified at Annex D shall be submitted to the Cospas-Sarsat Secretariat
|
||
for evaluation, retention, and distribution to Participants. Revisions or updates to commissioning
|
||
reports should be provided to the Secretariat with a clear indication given on the cover page of the
|
||
sections that have been revised and a short description of the nature of the revisions.
|
||
Those items not in compliance with the specification shall be highlighted in the appropriate portions
|
||
of the commissioning report.
|
||
2.7
|
||
GEOLUT Commissioning and Integration
|
||
The decision to approve the commissioning of a GEOLUT will be based on the information contained
|
||
in the GEOLUT commissioning report provided by the national Administration. The commissioning
|
||
report will be reviewed by the experts of the Joint Committee or an EWG tasked by the Cospas-Sarsat
|
||
Council to review LUT commissioning reports. The GEOLUT will be integrated into the Cospas-
|
||
Sarsat Ground Segment as described in Annex F and Annex G.
|
||
2.8
|
||
Confirmation of Requirements
|
||
The national Administration shall confirm compliance to all requirements detailed in this document
|
||
with either a measurement, verification, declaration, or combination of these methods. The exact
|
||
method of confirming compliance for each requirement is summarized at Annex I.
|
||
A measurement requires the national Administration to conduct a test and include the supporting data
|
||
as part of the commissioning report. A verification requires a national Administration to test a
|
||
requirement, however, supporting data does not need to be provided as part of the commissioning
|
||
report. A declaration of compliance confirms that specific requirements are met although not
|
||
necessarily tested as part of the commissioning process. Conformance to all requirements shall be
|
||
documented in the commissioning report.
|
||
|
||
2-3
|
||
|
||
2.9
|
||
Change of Location
|
||
If the location of a commissioned GEOLUT has been changed, the responsible national
|
||
Administrations shall ensure that the GEOLUT continues to satisfy C/S T.009 requirements prior to
|
||
resuming operations. Additionally, the national Administrations shall:
|
||
a)
|
||
confirm that the level of local interference does not adversely affect GEOLUT
|
||
performance;
|
||
b)
|
||
verify the performance of the communication links in the new location;
|
||
c)
|
||
verify the performance of the antenna and RF subsystems; and
|
||
d)
|
||
update the technical file of the GEOLUT commissioning report (Appendix 1 to
|
||
Annex A refers) by providing a declaration that the GEOLUT satisfies C/S T.009
|
||
requirements and the following information, to the Cospas-Sarsat Secretariat:
|
||

EVALUATION OF FUNCTIONAL AND PROCESSING REQUIREMENTS
|
||
4.1
|
||
Functional Requirements
|
||
4.1.1
|
||
Antenna and RF Subsystem
|
||
The national Administration shall verify and document in the GEOLUT commissioning report that the
|
||
antenna and RF subsystem of the GEOLUT can acquire and continuously receive the downlink signal
|
||
from the GEOSAR satellite(s) with which the GEOLUT will operate.
|
||
4.1.2
|
||
Time and Frequency Reference Subsystems
|
||
The national Administration shall declare, in the GEOLUT commissioning report, the GEOLUT’s
|
||
ability to satisfy time and frequency reference requirements detailed in document C/S T.009.
|
||
The GEOLUT may use one or more reference beacon signals to maintain the frequency stability
|
||
required to meet the specification. The identification of any such reference beacon(s) shall be included
|
||
in the GEOLUT Commissioning Report.
|
||
4.1.3
|
||
MCC Interface
|
||
The national Administration shall verify that the GEOLUT provides timely alert data of the level of
|
||
quality and detail as specified in document C/S T.009. This will enable the associated MCC to satisfy
|
||
the requirements of documents C/S A.002 (SID) and C/S A.005 (MCC Specification). This verification
|
||
shall be documented in the GEOLUT commissioning report.
|
||
4.2
|
||
Processing Requirements
|
||
The national Administration shall conduct tests and, record the results in the appropriate section of the
|
||
commissioning report, which confirm the GEOLUTs compliance to the “processing requirements”
|
||
detailed in document C/S T009.
|
||
These tests require the GEOLUT to process the 406 MHz data described at Annex C in the manner
|
||
prescribed. The processing consists of bit verification, message validation, message processing and
|
||
transmission. The specific beacon test messages contained at Annex C can be transmitted by a test
|
||
beacon or a beacon simulator.
|
||
National Administrations should ensure that test beacons or simulators are capable of transmitting the
|
||
beacon messages in the manner and at the frequencies described at Annex C. Alternatively, national
|
||
Administrations may arrange for the simulators in the United States or France to uplink the messages
|
||
contained at Annex C.
|
||
If the test messages cannot be transmitted during the commissioning period, the national
|
||
Administration may develop alternative methods of confirming compliance with the beacon message
|
||
processing requirements and proceed with the commissioning test, and preparation and submission of
|
||
the commissioning report. The unavailability of the test beacon or simulators to uplink the test shall
|
||
|
||
4-2
|
||
|
||
not prevent the GEOLUT from being commissioned, if other adequate methods are used. If alternative
|
||
methods are used, these methods shall be completely documented in the commissioning report.

ANNEX B - STATISTICAL REQUIREMENTS
|
||
B.1
|
||
GENERAL
|
||
This annex describes the test procedures, and the statistical elements that the national Administration
|
||
is to provide to the Cospas-Sarsat Secretariat for all tests and measurements required to commission a
|
||
GEOLUT. Data used to create these statistics must satisfy the criteria for inclusion detailed at Annex
|
||
E. A list of all 406 MHz beacons used for the statistical analysis shall be provided in accordance with
|
||
section B.2. The statistical information provided to the Cospas-Sarsat Secretariat shall be summarised
|
||
and included in the main portion of the commissioning report, as described at Annex A. Additionally,
|
||
the analysis and calculations used to derive the summarised information shall be documented, and also
|
||
included in the commissioning report as detailed at Annex A.
|
||
B.2
|
||
406 MHZ BEACONS USED
|
||
All 406 MHz beacon messages used in the generation of these statistical results / analysis shall be listed
|
||
in the commissioning report. Furthermore, except for the special signals generated to test the limits of
|
||
the GEOLUT’s capabilities, the national Administration shall confirm that the beacon signals and
|
||
messages generated satisfied the requirements of document C/S T.001 (beacon specification).
|
||
B.3
|
||
OPERATIONAL REQUIREMENTS - STATISTICAL DATA ELEMENTS
|
||
B.3.1
|
||
GEOLUT DATA AVAILABILITY (A)
|
||
This test shall be conducted by monitoring the GEOLUT operational performance during a 7 day period
|
||
(minimum), with a view to determining GEOLUT availability. The GEOLUT data availability (A) is
|
||
defined as: A = [1-(DT/T)] x 100 and shall be greater than or equal to 95, where T = test period and
|
||
DT = elapsed time during the test period, during which any GEOLUT basic function or requirement
|
||
cannot be performed.
|
||
The values for A, DT, and T shall be reported.
|
||
B.3.2
|
||
SATELLITE TRACKING CAPABILITY
|
||
This test shall be conducted by monitoring the duration that the GEOLUT lost carrier lock on the
|
||
GEOSAR satellite’s downlink carrier signal during a seven-day period (minimum) of operational use.
|
||
L = the elapsed time that the GEOLUT lost carrier lock on the GEOSAR satellite's downlink carrier
|
||
signal during the test period. L shall be equal to zero.
|
||
The value for L and the duration of the test period shall be reported.
|
||
|
||
B-2
|
||
|
||
B.4
|
||
PROCESSING REQUIREMENTS - STATISTICAL DATA ELEMENTS
|
||
This test demonstrates the GEOLUT’s ability to satisfy the processing requirements documented in
|
||
section 4.2 of document C/S T.009.
|
||
The preferred procedure to be used to validate these requirements is by using a beacon simulator to
|
||
transmit a series of beacon message test scripts detailed at Annex C. The resulting alert data produced
|
||
by the GEOLUT shall be analysed and compared to the expected results for each script. The national
|
||
Administration shall report the following in a tabular format:
|
||
a.
|
||
the identification of each test script (provided to the national Administration by the
|
||
beacon simulator provider);
|
||
b.
|
||
the date and time that each beacon activation occurred;
|
||
c.
|
||
the expected result(s) for each beacon activation;
|
||
d.
|
||
the actual result(s) produced by the GEOLUT for each beacon activation; and
|
||
e.
|
||
an indication of whether the GEOLUT satisfied the applicable processing
|
||
requirements.
|
||
If a suitable beacon simulator is not available, then this test may be performed using a software
|
||
simulator connected directly to the GEOLUT (as opposed to beacon simulators which radiate signals).
|
||
The beacon simulator shall replicate the beacon message test scripts that were developed for the beacon
|
||
simulator. These test scripts are detailed at Annex C.
|
||
B.5
|
||
PERFORMANCE REQUIREMENTS - STATISTICAL DATA ELEMENTS
|
||
B.5.1
|
||
PROCESSING PERFORMANCE
|
||
This test demonstrates the GEOLUT’s ability to satisfy the processing performance requirements
|
||
detailed in document C/S T.009.
|
||
The preferred procedure to validate this requirement is to use a beacon simulator to radiate the beacon
|
||
message test scripts detailed at Annex C. Before the test scripts are activated, the national
|
||
Administration shall liaise with the provider of the beacon simulator to calibrate the radiated power
|
||
level of the beacon simulator to produce the required C/No at the GEOLUT. Upon completion of the
|
||
test, the resulting alert data produced by the GEOLUT shall be analysed and compared to the expected
|
||
results for each script. The national Administration shall report the following:
|
||
a.
|
||
the identification of each test script (provided to the national Administration by the
|
||
beacon simulator provider);
|
||
b.
|
||
the date and time that each test script was run;
|
||
c.
|
||
the beacon alert message transmitted for each beacon activation;
|
||
d.
|
||
the actual beacon alert message produced by the GEOLUT for each beacon activation;
|
||
e.
|
||
the time duration required by the GEOLUT to provide a suitable valid message; and
|
||
|
||
B-3
|
||
|
||
f.
|
||
an indication of whether the GEOLUT satisfied the applicable processing
|
||
requirements.
|
||
If a suitable beacon simulator is not available, then this test may be performed using real beacons
|
||
whose output power can be adjusted. If this procedure is used, then the number of beacon signals, their
|
||
duration, and power levels shall replicate the beacon test scripts detailed at Annex C.
|
||
B.5.2
|
||
FREQUENCY MEASUREMENT
|
||
This test measures the ability of the GEOLUT to measure the transmitted frequency of beacons signals
|
||
to the specifications detailed in document C/S T.009.
|
||
The preferred procedure to validate this requirement is to use orbitography or reference beacons with
|
||
known frequency performance characteristics. For each valid beacon message processed by the
|
||
GEOLUT, the difference between GEOLUT measured frequency and the actual transmitted frequency
|
||
shall be calculated and documented. The largest, average and smallest frequency differences shall be
|
||
reported. Furthermore, the ratio of messages with frequency measurements accurate to within 2 Hz to
|
||
the total number of valid beacon messages shall be calculated and documented. This ratio shall be
|
||
0.95 or better. The frequency specifications of the orbitography or reference beacons used in this test
|
||
shall be confirmed and reported. A minimum of 100 measurements shall be made for this test.
|
||
If suitable orbitography or reference beacons are not within the satellite coverage area then a beacon
|
||
simulator can be used. The simulator shall radiate the beacon messages detailed at Annex C. For each
|
||
valid beacon message processed by the GEOLUT, the difference between GEOLUT measured
|
||
frequency and the actual transmitted frequency shall be calculated and documented. The largest,
|
||
average and smallest frequency differences shall be reported. Furthermore, the ratio of messages with
|
||
frequency measurements accurate to within 2 Hz to the total number of valid beacon messages shall
|
||
be calculated and documented. This ratio shall be 0.95 or better. The frequency specifications of the
|
||
beacon simulator shall be confirmed and reported.
|
||
The identifier(s) of the test or reference beacon(s) used to verify the frequency stability of the
|
||
GEOLUT shall be reported in the commissioning report.

||
GENERAL
|
||
This annex describes the data format to be provided to the Cospas-Sarsat Secretariat separately from a
|
||
commissioning report. The data is to be provided in three separate electronic text files, one for the
|
||
tracking database (section D.2), the solution data (section D.3), and the beacon database (section D.4).
|
||
The data is to be provided in a comma (,) delimited format, and each field shall include an entry. If
|
||
there is no data for any given field, then a blank space is to be inserted into the appropriate portion of
|
||
the file. All data used in the commissioning testing are to be provided.
|

ANNEX E - TEST CONDITIONS
|
||
E.1
|
||
GENERAL
|
||
This annex defines the test conditions, and criteria for including and excluding test result data in the
|
||
GEOLUT commissioning report.
|
||
E.2
|
||
BEACONS
|
||
All tests performed for GEOLUT commissioning purposes shall be conducted using type approved
|
||
Cospas-Sarsat beacons coded with the test protocol or a beacon simulator (where appropriate). The
|
||
sole exception is when specific tests cannot be conducted with type approved beacons (i.e. processing
|
||
threshold test). Except for the frequency measurement test, orbitography or reference beacons that are
|
||
in the GEOSAR satellite's uplink field of view are not to be used for commissioning tests.
|
||
The concept of a beacon activation is used in the test procedures detailed at Annex B and the data
|
||
requested at Annex D. A beacon activation is defined as the beacon's signal being transmitted through
|
||
a GEOSAR satellite for a predetermined number of times at the beacon burst repetition rate defined in
|
||
document C/S T.001, and a GEOLUT output message being generated and the beacon's signal being
|
||
turned off. In this manner a beacon activation is to represent and/or simulate how a beacon would be
|
||
used operationally. If the same beacon signal is to be reused later, sufficient time between the
|
||
activations must be allowed for the previous beacon's signal to be removed from the GEOLUT's
|
||
processor memory.
|
||
E.3
|
||
SOLUTION STATISTICS
|
||
GEOLUT output messages meeting one or more of the following criteria shall be eliminated from the
|
||
statistics:
|
||
a.
|
||
messages known to have been interfered with by other emitters in the 406 MHz band
|
||
in the GEOSAR satellite's uplink field of view;
|
||
b.
|
||
messages received from beacons located such that their elevation angle to the
|
||
GEOSAR satellite is less than four (4) degrees from the local horizon; and
|
||
c.
|
||
messages known to have been received during periods of interference by the LEOSAR
|
||
satellites with the GEOSAR satellites' downlink signals.
|
||
In cases where the GEOLUT was not able to satisfy document C/S T.009 requirements or the minimum
|
||
standards for testing as documented herein because of situations described above, then the affected
|
||
tests shall be redone.
|
||
E.4
|
||
SOLUTION DATA
|
||
The GEOLUT output messages shall be provided for all test and orbitography beacons used during the
|
||
test period.

The Cospas-Sarsat Council approved the general principles of its commissioning policy for GEOLUTs,
|
||
provided hereunder in Sections F.2, F.3, and F.4, at its Twenty-First Session.
|
||
F.2
|
||
GENERAL
|
||
The following principles govern the commissioning of Cospas-Sarsat Ground Segment equipment:
|
||
F.2.1
|
||
A State which has notified its association with the Cospas-Sarsat Programme as a Ground
|
||
Segment Provider assumes the responsibility "to adhere to the technical specifications
|
||
and operating procedures set by the Council for the purpose of ensuring adequate System
|
||
performance" and "to provide, as agreed with the Council, appropriate performance data
|
||
in order to confirm compatibility of its Ground Segment equipment with the System"
|
||
(Section 3.1 of the Letter of Notification).
|
||
F.2.2
|
||
Cospas-Sarsat performance standards and design guidelines of GEOLUTs and MCCs are
|
||
defined in documents C/S T.009 and C/S A.005, respectively.
|
||
F.2.3
|
||
Cospas-Sarsat criteria and test methods for verifying that GEOLUTs and MCCs meet
|
||
these standards are defined in documents C/S T.010 and C/S A.006, respectively.
|
||
F.2.4
|
||
The responsible Agency or Administration installing or planning to operate a new
|
||
GEOLUT or MCC shall plan and conduct appropriate tests, in accordance with the
|
||
applicable Cospas-Sarsat standards, which may form part of its own acceptance testing.
|
||
F.2.5
|
||
A commissioning report, including the results of the commissioning tests defined by
|
||
Cospas-Sarsat, shall be submitted to the Cospas-Sarsat Secretariat, for review by the
|
||
Joint Committee or an EWG established by the Cospas-Sarsat Council to review LUT
|
||
commissioning reports and be subsequently submitted by the Ground Segment Provider
|
||
as per the meeting submission deadline.
|
||
F.2.6
|
||
After review of the commissioning report, appropriate recommendations to the Cospas-
|
||
Sarsat Council are made. Formal commissioning is recorded at the subsequent Council
|
||
meeting, after approval of the recommendation by the Council.
|
||
|
||
F-2
|
||
|
||
F.2.7
|
||
This commissioning and reporting procedure shall be implemented by all Cospas-Sarsat
|
||
Ground Segment operators, including Parties to the International Cospas-Sarsat
|
||
Programme Agreement, for commissioning new GEOLUTs and MCCs or new
|
||
equipment or functions which have a significant impact on the Cospas-Sarsat Ground
|
||
Segment operation.
|
||
F.2.8
|
||
The cost of implementing the commissioning procedure and reporting to Cospas-Sarsat
|
||
is borne by the operating Agency or Administration installing the equipment to be
|
||
commissioned.
|
||
F.2.9
|
||
Ground Segment equipment will be commissioned into the Cospas-Sarsat System only
|
||
if the formal association of the GEOLUT and the MCC operator with the Cospas-Sarsat
|
||
Programme has been notified in accordance with the standard procedure, unless
|
||
otherwise agreed by the Council.
|
||
F.3
|
||
GEOLUT COMMISSIONING
|
||
The following principles govern the implementation of the Cospas-Sarsat GEOLUT Commissioning
|
||
Standard (C/S T.010):
|
||
F.3.1
|
||
The implementation of the commissioning procedure defined in document C/S T.010 is
|
||
the responsibility of the operating Agency or Administration.
|
||
F.3.2
|
||
The operating Agency or Administration will be responsible for equipment which may
|
||
be required for performing the commissioning tests.
|
||
F.3.3
|
||
For a GEOLUT to be commissioned it must be connected to its associated MCC.
|
||
F.3.4
|
||
The GEOLUT/MCC interface is tested as part of the GEOLUT commissioning.
|
||
F.3.5
|
||
If the test results in the commissioning report submitted by the operating Agency or
|
||
Administration do not demonstrate full compliance with document C/S T.009 (GEOLUT
|
||
performance specification), corrective action shall be taken.
|
||
F.3.6
|
||
If the test results in the commissioning report submitted by the operating Agency or
|
||
Administration do demonstrate full compliance with document C/S T.009 (GEOLUT
|
||
performance specification), the alert data derived from the new GEOLUT can be
|
||
immediately used by the associated MCC for distribution in accordance with the Cospas-
|
||
Sarsat Data Distribution Plan (C/S A.001).
|
||
|
||
F-3
|
||
|
||
F.3.7
|
||
Once the alert data derived from the new GEOLUT begins to be used by the associated
|
||
MCC, a change of System status shall be distributed to all MCCs by the associated MCC,
|
||
in accordance with the procedure of document C/S A.001.
|
||
F.3.8
|
||
The Joint Committee or an EWG established by the Council for the purpose reviews the
|
||
LUT commissioning report and recommends to the Cospas-Sarsat Council, as
|
||
appropriate, formal commissioning of the GEOLUT.

G-1
|
||
|
||
ANNEX G - GUIDELINES FOR INTEGRATION OF NEW GEOLUTS IN THE
|
||
COSPAS-SARSAT SYSTEM
|
||
The introduction of new GEOLUTs in the Cospas-Sarsat System is supervised by the Joint Committee
|
||
or an EWG body tasked by the Cospas-Sarsat Council to review LUT commissioning reports whose
|
||
objectives support:
|
||
a)
|
||
the improvement of the overall performance of the Cospas-Sarsat Ground Segment; and
|
||
b)
|
||
the technical control of the development of the Cospas-Sarsat LUTs.
|
||
The guidelines hereunder, and Figure G.1, provide procedures for integrating a new GEOLUT into the
|
||
Cospas-Sarsat Ground Segment.
|
||
1.
|
||
Installation of New Equipment - The new GEOLUT(s) equipment should be sited to provide for
|
||
good reception from the GEOSAR satellite with which it is to operate. The location of the
|
||
GEOLUT(s) should also allow for reliable communications with the associated MCC.
|
||
2.
|
||
GEOLUT Description - The national Administration should ensure that a description of the new
|
||
GEOLUT(s) along with (1) co-ordinates, (2) address, and (3) uplink frequency bandwidth are
|
||
provided to the Cospas-Sarsat Secretariat.
|
||
The national Administration should also ensure that their GEOLUT(s) is (are) properly
|
||
registered with the International Telecommunications Union (ITU). The forms provided in
|
||
Annex H to this document should be completed and forwarded to ITU through the appropriate
|
||
national authorities.
|
||
3.
|
||
Commissioning Test - For new Ground Segment Providers, the GEOLUT Commissioning tests
|
||
may be scheduled to coincide with the MCC commissioning tests. In any case, the GEOLUT
|
||
should be connected to the MCC and tested in its operational configuration.
|
||
The GEOLUT Operator should ensure that test beacon(s) capable of transmitting the test code
|
||
sequences contained in Annex C is (are) available for the commissioning test, or the GEOLUT
|
||
Operator should co-ordinate with beacon simulator providers in the USA or France for the
|
||
transmission of such code sequences. If test beacons/simulators cannot be used during the
|
||
commissioning test, the GEOLUT Operator should ensure that an alternative method of
|
||
confirming compliance is identified.
|
||
The relevant sections of this document describe the operational, functional and processing, and
|
||
performance requirements to be tested. During the test, the data from the GEOLUT(s) should
|
||
be transmitted to the associated MCC, however, the data should be suppressed by the MCC and
|
||
not transmitted within the Cospas-Sarsat System.
|
||
4.
|
||
Preparation of Commissioning Report - The results of the tests, along with the proper
|
||
declarations and verifications for items not specifically tested, should be documented in a
|
||
commissioning report. Annex A to this document contains the format of the commissioning
|
||
report.
|
||
|
||
G-2
|
||
|
||
The commissioning report should include as a minimum the information requested in this
|
||
document and in the format contained in Annex A. In addition, information to explain or clarify
|
||
results should also be included in the commissioning report.
|
||
Any anomaly, or failure to meet a requirement, observed during the commissioning test should
|
||
be corrected and the requirement re-tested. After the GEOLUT satisfies the requirements of
|
||
document C/S T.009, “Cospas-Sarsat GEOLUT Performance Specification and Design
|
||
Guidelines,” the completed commissioning report should be submitted by the national
|
||
Administration to the Cospas-Sarsat Secretariat.
|
||
5.
|
||
Initial Operational Capability (IOC) - If the commissioning test has been completed successfully,
|
||
and the commissioning report has been forwarded to the Cospas-Sarsat Secretariat, the GEOLUT
|
||
may begin operations in an IOC status. However, the GEOLUT cannot reach IOC status prior
|
||
to the MCC IOC date if the associated MCC is also in the commissioning process. The national
|
||
Administration, through its associated MCC, should notify all Ground Segment Operators of a
|
||
GEOLUT’s IOC status via a System Status message.
|
||
The IOC phase allows a thorough review of the GEOLUT performance. However a GEOLUT
|
||
shall not remain in an IOC phase for more than one year. GEOLUTs that have not reached FOC
|
||
within one year will be considered not operational, and documented as “Under Development”.
|
||
To regain IOC status the GEOLUT will require a retest of the elements which prevented it from
|
||
reaching FOC. The GEOLUT then must operate again in an IOC phase prior to reaching FOC.
|
||
All Cospas-Sarsat Ground Segment Operators should monitor the data from new GEOLUTs for
|
||
any significant anomalies that could impact Cospas-Sarsat operations.
|
||
6.
|
||
Full Operational Capability (FOC) - If after 90 days of operation in an IOC state no anomalies
|
||
are detected in the performance of the GEOLUT, the GEOLUT should be declared at FOC by
|
||
the appropriate nodal MCC. The transition of a GEOLUT from an IOC status to a FOC status
|
||
ensures that the GEOLUT performs to Cospas-Sarsat standards and does not negatively impact
|
||
System operations.
|
||
7.
|
||
Formal Commissioning - The Joint Committee or an EWG established by the Cospas-Sarsat
|
||
Council for the purpose reviews the commissioning report and, pending additional details or
|
||
explanations, provides recommendations on the approval of the report and the commissioning
|
||
of the GEOLUT into the Cospas-Sarsat Ground Segment to the Council. The Council approves
|
||
the recommendation and decides that the GEOLUT is formally commissioned in the Cospas-
|
||
Sarsat Ground Segment.
|
||
8.
|
||
GEOLUTs with Limited Data Availability - A GEOLUT which does not satisfy document
|
||
C/S T.009 data availability requirements (e.g. GEOLUTs which share equipment with
|
||
LEOLUTs) will be authorised to provide their alert data into the System upon the successful
|
||
completion of the GEOLUT commissioning tests. Such GEOLUTs will follow the integration
|
||
process described in this annex for full time GEOLUTs, however, such equipment will not be
|
||
reported as operational GEOLUTs when reporting the status of the System.
