Which of the following statements concerning COSPAS-SARSAT is false?

After initiating a call request and selecting the CES, these satellites may be used for commercial messages.
EPIRBs are used primarily for distress alerting.
These satellites are looking specifically for EPIRB signals on 406 MHz.
These satellites use Doppler shift measurement to determine the location of the beacons.

What feature is not found on 406 MHz satellite EPIRB units?

Which is a function of a satellite under COSPAS-SARSAT using satellite EPIRBs?

Vessel information recovered from the digital encoded message provided by the satellite EPIRB.
Information received from EPIRBs are time-tagged and transmitted to any Local User Terminal in the satellite's view.
Doppler shift of EPIRB signal is measured.
All of these.

Which of the following statements concerning satellite EPIRBs is true?

The coded signal identifies the nature of the distress situation.
The coded signal only identifies the vessel's name and port of registry.
Once activated, these EPIRBs transmit a signal for use in identifying the vessel and for determining the position of the beacon.
If the GMDSS Radio Operator does not program the EPIRB, it will transmit default information such as the follow-on communications frequency and mode.

A distress signal transmitted from which EPIRB is relayed by an INMARSAT satellite.

Which is not a valid maintenance and testing function for an SART?

Inspection of container for apparent damage.
Operational test with several vessels to determine effective transmitting range.
Brief operational test utilizing own ship's radar.
Inspect battery expiration date and the lanyard condition.

Which of the following statements concerning COSPAS-SARSAT is true?

The Doppler frequency measurement concept is used to determine the EPIRB's location.
These are satellites in a low-earth polar orbit that detect EPIRB beacons on 406 MHz and relay the information to an earth-side Local User Terminal (LUT).
EPIRBs are units that are used as alerting devices.
All of the above.
