GUIDELINES FOR PARTICIPATING IN THE
COSPAS-SARSAT SYSTEM
This document provides basic information on principles governing the access to, and use of
the Cospas-Sarsat System, and recommendations which States should endeavour to
implement for ensuring efficient System operations. Basic information is also provided on
the procedure for association with the International Cospas-Sarsat Programme.
1.
PRINCIPLES GOVERNING THE USE OF THE COSPAS-SARSAT SYSTEM
1.1
The International Cospas-Sarsat Programme Agreement
The Cospas-Sarsat Programme is established under the International Cospas-Sarsat
Programme Agreement (referred to as the Agreement), signed in Paris on 1 July 1988 by
Canada, France, the USSR1 and the USA. This Agreement is open for accession by other
States which provide, in agreement with the Parties, space segment capabilities. The
Secretary-General of the International Civil Aviation Organization (ICAO) and the
Secretary-General of the International Maritime Organization (IMO) are the joint Depositaries
of the International Cospas-Sarsat Programme Agreement.
The Agreement, which entered into force on 30 August 1988, ensures the continuity of the
satellite system and its availability to all States on a non-discriminatory basis, and free of
charge for the end-user in distress (Preamble and Article 6 of the Agreement). The
Agreement also specifies that the transmission and the reception of distress alert data through
the Cospas-Sarsat Space Segment shall be provided free of charge to all States (Article 6.3).
1.2
Availability of the System to States Non-Party to the Cospas-Sarsat Agreement
The International Cospas-Sarsat Programme Agreement provides for the association of
non-Party States with the Programme. Such association is welcomed by the Cospas-Sarsat
Parties and is considered mutually beneficial, although any State may avail itself of the
Cospas-Sarsat System by authorising the use of compatible distress beacons, and may use
alert data from the System, without being formally associated with the Programme.
In this context, it should be noted that the frequency bands (beacon-to-satellite and satellite-
to-ground receiving stations) used in the Cospas-Sarsat System, are limited to distress and
safety operations. The Radio Regulations of the International Telecommunication Union
(ITU) impose strict discipline on the use of distress and safety frequencies and require that
distress alerts be routed as soon as possible to Rescue Co-ordination Centres (RCCs).
Alert and location data from distress beacon transmissions at 406 MHz obtained by existing
Cospas-Sarsat ground receiving stations (referred to as Local User Terminals or LUTs) are
distributed to nationally designated search and rescue (SAR) Authorities by the appropriate
Russian Party: The Russian Federation has replaced the former USSR as a Party to the International
Cospas-Sarsat Programme Agreement.
C/S P.007(E) - Issue 5 - Rev. 1
Cospas-Sarsat Mission Control Centre (MCC), as defined in the Cospas-Sarsat Data
Distribution Plan (document C/S A.001).
1.3
Ground Segment Providers
The objective of the Cospas-Sarsat Programme is to provide and distribute Cospas-Sarsat
alert data world-wide, in support of efforts in the International Maritime Organization to
establish the Global Maritime Distress and Safety System (GMDSS) of which Cospas-Sarsat
is part, and in the International Civil Aviation Organization to enhance aeronautical SAR
services. Managing a Cospas-Sarsat MCC and one or more LUTs requires a sustained
national commitment to provide reliable, accurate and timely alert data continuously, to
organizations with search and rescue responsibilities.
National authorities wishing to become Cospas-Sarsat Ground Segment Providers need to
co-ordinate their MCC and LUT operations with the providers of the satellite system and
other Cospas-Sarsat Participants. This involves, in particular, notifying their formal
association with the Cospas-Sarsat Programme as described in section 3 of this document,
and participating in the international meetings of the Cospas-Sarsat Programme. International
co-ordination requirements for Ground Segment Providers are further detailed in section 2.1.
All Ground Segment elements are to be commissioned before their use in the Cospas-Sarsat
System. Commissioning procedures have been developed to ensure the reliability of alert
data provided by LUTs and their timely distribution by MCCs to the appropriate RCC or
other SAR Point of Contact (SPOC). Only States formally associated with the Cospas-Sarsat
Programme can have their LUTs and MCCs commissioned in the Cospas-Sarsat System.
2.
RESPONSIBILITIES OF ADMINISTRATIONS / GOVERNMENT AGENCIES
2.1
Ground Segment Management
2.1.1
LUT/MCC Operations
States contributing a Cospas-Sarsat MCC and LUT facility are also committing to support
continuous operations, 24 hours a day, seven days a week. Sufficient personnel must be made
available to maintain this ongoing responsibility. Contingency plans should be established
for the loss of LUT or MCC operations.
2.1.2
System Maintenance and Enhancements
The Cospas-Sarsat System is a dynamic system that may require reactive, adaptive
modifications or enhancements to Ground Segment elements. Reactive modifications may be
necessary to resolve anomalies in Ground Segment processing. Adaptive modifications may
be necessary to accommodate changes in message formats between MCCs or data formats
received from Cospas-Sarsat satellites. Enhancement modifications can result from agreed
changes in data distribution procedures.
All Ground Segment Providers should ensure that the proper management structure and
contractual instruments exist to maintain, modify and enhance their LUT(s) and MCC,
C/S P.007(E) - Issue 5 - Rev. 1
according to the agreed specifications and procedures provided in the Cospas-Sarsat System
documentation, as approved and amended from time to time by the Cospas-Sarsat Council.
2.1.3
Co-ordination of Activities
The designated national Representative in Cospas-Sarsat is responsible for all actions
required for the integration of Ground Segment elements in the Cospas-Sarsat System.
Although Administrations may seek the support of commercial contractors, national
authorities are requested to establish and maintain direct lines of communications with other
Cospas-Sarsat Participants and the Cospas-Sarsat Secretariat.
Attendance and participation at open Cospas-Sarsat Council meetings and Joint Committee
meetings is vital to information exchange and helps ensure that national MCCs and LUTs are
operating within the requirements of Cospas-Sarsat. The head of the national programme or
designated Representative should attend the Open Meetings of Cospas-Sarsat Council
sessions. MCC/LUT operation managers should attend Cospas-Sarsat Joint Committee
meetings. The benefits of the meetings offer each participating country a comprehensive
working knowledge of the Cospas-Sarsat System and documentation to reinforce their
experience of System operations.
Communication with neighbouring MCCs should be accompanied by visits to observe
management techniques and operation procedures. National organizations responsible for the
management of Cospas-Sarsat Ground Segment equipment are highly encouraged to schedule
meetings/visits with the associated nodal MCC which provides the interface with the Cospas-
Sarsat network.
2.1.4
Elimination of Interference
Interference in the 406 MHz frequency band limits the performance of the Cospas-Sarsat
System by preventing receipt of distress beacon transmissions in regions where interfering
transmitters are operating. Participants should endeavour to detect, locate and turn off these
interfering signals in their national areas of responsibility, as described in ITU
Recommendation ITU-R SM.1051.
2.2
Practical Aspects of the Use of The Cospas-Sarsat System
Distress beacons for use with the Cospas-Sarsat System operate at 406 MHz. They are
referred to as:
-
Emergency Position Indicating Radio Beacons (EPIRBs) when designed for use
on vessels;
-
Emergency Locator Transmitters (ELTs) when designed for use on aircraft; and
-
Personal Locator Beacons (PLBs) when designed for use by individuals.
To ensure efficient use of the Cospas-Sarsat System, the following matters should be
addressed by all administrations or government agencies responsible for search and rescue
services:
C/S P.007(E) - Issue 5 - Rev. 1
2.2.1
SAR Points of Contact (SPOCs)2
- Designate a single SAR point of contact (SPOC) for receiving Cospas-Sarsat alert and
location data, for distress locations in their SAR area of responsibility.
- Provide the address, telephone, telex or facsimile number or AFTN address of their
SPOC to the Cospas-Sarsat Secretariat.
- Develop a comprehensive plan for the distribution of alert and location data to SAR
authorities, as appropriate.
2.2.2
Distress Beacons Control
- Ensure that only type-approved 406 MHz distress beacons are used with the Cospas-
Sarsat System.
- Take measures to ensure that the protocols used for coding beacons are compatible with
the specification in ITU Recommendation ITU-R M.633-3 or Cospas-Sarsat document
C/S T.001.
- Ensure that the transmitted digital message includes an identification code which makes
it possible to identify with the greatest possible certainty, ships, aircraft or land users in
distress, and comprises:
-
three digits identifying the county of registration in accordance with the list of
country codes, (which is based on the ITU list of Maritime Identification Digits
(MIDs); and
-
about 40 bits used to identify the individual beacon, according to one of the
agreed protocols defined in Recommendation ITU-R M.633-3 or Cospas-Sarsat
document C/S T.001.
2.2.3
Beacon Registration
- Maintain, in accordance with the requirement of Annex 10 of the ICAO Convention
and with IMO Assembly Resolution A.887(21), a current register for all 406 MHz ELTs
and EPIRBs, to establish the correspondence between a 406 MHz ELT/EPIRB and its
owner or its carrier vehicle. Beacon registration is particularly important when
serialized protocols are used (i.e. each beacon is identified by a unique serial number),
as the beacon register is the only means by which the identity of the beacon owner/user,
or the carrier vehicle in distress, can be established.
- Maintain a current register for all 406 MHz PLBs, to establish the correspondence
between a PLB and its owner or user.
SPOCs / MCCs Co-ordination:
SPOCs serve as the interface with the Cospas-Sarsat System when
co-ordination is required or when information is requested from Cospas-Sarsat on a specific SAR event.
Information on the designated SPOC should be forwarded to IMO, ICAO or the Cospas-Sarsat
Secretariat.
C/S P.007(E) - Issue 5 - Rev. 1
- Provide Cospas-Sarsat with the details of their 406 MHz beacon register (address,
telephone, facsimile, or telex number, etc.) where SAR services can obtain information
on the ship, or aircraft which is carrying a transmitting beacon, or the owner of a PLB.
The information contained in the beacon register should be made available to SAR
services, 24 hours/day and 7 days/week, to facilitate the expeditious processing of
Cospas-Sarsat distress alerts.
- In the event that a national beacon register for 406 MHz beacon is not available, inform
beacon owners of the availability of the International Beacon Registration Database
(IBRD) for registration of their 406 MHz beacons.
- Request appropriate usernames and passwords for access to the IBRD and inform the
IBRD Administrator (i.e. the Cospas-Sarsat Secretariat) of the appointed national
contact for IBRD matters. The national IBRD point of contact is responsible for
distributing the appropriate usernames and passwords to national SAR services,
authorized ship and aircraft inspectors and maintenance facilities, as appropriate.
2.2.4
Beacon Specifications
Administrations should note that the satellite processing of 121.5 MHz transmissions ceased
on 1 February 2009.
Transmission requirements applicable to 406 MHz beacons are defined in Recommendation
ITU-R M.633-3, in Annex 10 of the ICAO Convention, and in the Cospas-Sarsat
specification document C/S T.001.
The Cospas-Sarsat specification addresses the transmission characteristics of Cospas-Sarsat
beacons, but does not address other international or national requirements regarding
packaging or installation. These requirements should, however, be included in the
appropriate national specification for 406 MHz EPIRBs, ELTs or PLBs.
2.2.5
Beacon Type Approval
The purpose of type approval is to ensure that satellite EPIRBs, ELTs or PLBs operating
through the Cospas-Sarsat System will not degrade the System performance and to ensure
that their emissions are compatible with the space-borne equipment. The responsibility for
type approval of all types of distress beacons is that of individual States.
To assist States on type approval of 406 MHz beacons, Cospas-Sarsat has developed a
procedure which is defined in document C/S T.007. Once a beacon model has been
successfully tested according to the Cospas-Sarsat procedure, the Cospas-Sarsat Secretariat
will provide the manufacturer a Cospas-Sarsat 406 MHz Beacon Type Approval Certificate.
States may choose to rely on the results of Cospas-Sarsat type approval testing for national
type approval, as an alternative to re-testing the 406 MHz transmission characteristics of
the beacons.
The Cospas-Sarsat type approval procedure for 406 MHz beacons does not cover the
mechanical and environmental specifications of distress beacons, or their installation on
C/S P.007(E) - Issue 5 - Rev. 1
board ships or aircraft. Therefore, States should ensure that the applicable requirements have
been properly addressed by manufacturers, before approving a particular model.
3.
NON-PARTY STATES ASSOCIATION WITH THE COSPAS-SARSAT
PROGRAMME
States which are not Parties to the Agreement can participate formally in the Cospas-Sarsat
System either as Ground Segment Providers or User States.
3.1
Notification of Association
Ground Segment Providers are those States which establish and operate a LUT, to receive and
process satellite transmissions, and an MCC, to receive the required System information and
forward alert and location data according to the Cospas-Sarsat Data Distribution Plan. In
order to ensure that this ground segment equipment is efficiently operated and adequately
integrated into the Cospas-Sarsat ground network, Ground Segment Provider States
co-ordinate their activities with other States participating in the Cospas-Sarsat System and
notify their participation pursuant to Article 11 of the Agreement.
User States are those States which participate in the Cospas-Sarsat System and co-ordinate
their activities with other participating States, but which do not implement ground segment
facilities. These States are invited to notify their participation as User States pursuant to
Article 12 of the Agreement.
The notification procedure calls for Ground Segment Providers and User States to notify one
of the Depositaries of the Agreement of their participation, through standard letters approved
by the Cospas-Sarsat Council.
The purpose of the notification procedure is:
(i)
to specify clearly the respective responsibilities of the Parties to the Agreement
and of participating States, as defined in Articles 11 and 12 of the International
Cospas-Sarsat Programme Agreement; and
(ii)
to establish the basis of future working relations between the Co-operating
Agencies designated by the Parties for implementing the Agreement, and the
Agencies designated by the participating States to carry out their responsibilities.
3.2
Participation in the Meetings of the Programme
The following principles govern the participation of non-Party States associated with the
Programme in Cospas-Sarsat meetings:
- All States (i.e. User States and Ground Segment Provider States) having notified their
association with the Cospas-Sarsat Programme, pursuant to Article 11 or Article 12 of
the Agreement, are entitled to participate in the open meetings of the Programme,
including the open meetings of the Council and the meetings of its subsidiary organs
(e.g. the Joint Committee and its Working Groups).
C/S P.007(E) - Issue 5 - Rev. 1
- States associated with the Programme are entitled to receive all documents pertaining to
the open meetings of the Council and its subsidiary organs, to address those meetings,
submit papers, propose agenda items and have their views recorded in the Summary
Record of the Council Session or the Joint Committee Report to the Council.
- Administrations may request to attend Cospas-Sarsat meetings pending completion of
the procedure for their association with the Cospas-Sarsat Programme.
3.3
Contributions to the Common Costs of the Programme
Pursuant to Article 6 of the Agreement, non-Party Participants contribute financially towards
the Common Costs of the Programme as decided in agreement with the Council. The
Common Costs of the Programme are those associated with the organization, the
administration and co-ordination of the Programme, including Cospas-Sarsat Meetings and
Secretariat expenditures. In accordance with the decisions taken by the Council, the
following principles govern the contribution by non-Party Participants towards the Common
Costs of the Programme.
- All associated States pay each year a flat fee (payable in CAD), as their contribution to
the Common Costs of the Programme.
- This flat fee is currently set at CAD 68,000. The level of the yearly contribution
applicable after 2019 will be reviewed by the Council in agreement with non-Party
States associated with the Programme.
- Details regarding the Common Costs of the Programme will be provided to Participants
for discussion at the open meeting of the Council, three years in advance of any
proposed changes in non-Party States' contributions.
- The costs incurred by the Parties or the Ground Segment Providers for the
establishment of the System, its maintenance and its operation are not included in the
Common Costs of the Programme.
