It encompasses all radio, satellite, telephone, and network facilities owned/leased, controlled, and used by the CG. This includes associated terminal facilities, equipment, tools, techniques, and procedures. |
|
|
Mission of the CGTS |
a. Provide and maintain rapid, reliable, secure or protected, and interoperable telecommunications to meet Coast Guard operational requirements. b. Ensure connectivity, compatibility, and interoperability with the National Command Authority (NCA). c. Fulfill national and international obligations to provide public maritime safety notices and distress communication services for the safety of life at sea. |

|
|
Satellite EPIRB |
Used for distress alerting and locating survivors of distress incidents (406 MHz). EPIRBs are 406 MHz distress beacons and designed to transmit an alerting and locating signal when activated, usually by floating free when a vessel goes below the surface of the water, using 406 MHz |
|
|
Emergency Position-Indicating Radio Beacon (EPIRB) Classes |
(a) Category I – 406/121.5 MHz Homing Signal. Free-floating, automatically activated, and detectable by satellites anywhere in the world. This type of EPIRB is recognized by GMDSS; and (b) Category II – 406/121.5 MHz Homing Signal. Similar to Category I, but manually activated. Some models are also water activated |
|
|
Emergency Position-Indicating Radio Beacon (EPIRB) Signals |
The 406 MHz distress alerting signal is a short digital burst approximately every 50 seconds and the low power 121.5 MHz homing signal on the EPIRB is comprised of an upward-sweeping tone |
|
|
Search and Rescue Transponder (SART) |
The radar SART, operating in the 9200-9500 MHz frequency band, is a transponder used for locating survival craft |
|
|
Further information on the SART |
(1) The SART signal appears as a distinctive line of 12 equally spaced blips (dots) on a radar screen extending outward from the SART position along its line of bearing. (2) Unique signals (swept frequency) are generated for interpretation only after being triggered by 9 GHz ship or aircraft radar. (3) Range of air is 40 nautical miles; surface is 10 nautical miles. (4) An audible alarm or light is activated on the SART when a rescue ship or aircraft is within close range. (5) Battery capacity shall be at least 96 hours |
|
|
AIS SART |
(1) The AIS-SART message indicates the position, static and safety information of the unit in distress. (2) The AIS-SARTs should be detectable at a range of 5 nautical miles over water. (3) The AIS-SART should continue transmission even if the position and time synchronization from the positioning system is lost or fails. (4) The AIS-SART should transmit within 1 minute of activation. (5) Battery capacity shall be at least 96 hours |
|
|
MMSI Numbers |
Maritime Mobile Service Identity; nine digit numbers used by maritime DSC, AIS, and certain other equipment to uniquely identify a ship or a coast radio station. MMSIs are regulated and managed internationally by ITU, just as radio call signs are regulated |
|
|
Record Message Classes |
a. Class A. Official record messages originated by the DOD, including the CG when operating as part of the USN; b. Class B. Official record messages originated by United States government departments and agencies other than DOD. The CG is included under Class B, except when operating as a part of the USN; and c. Class C.
