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

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

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

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

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

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

The Doppler frequency measurement concept is used to determine the EPIRB's location.
EPIRBs are units that are used as alerting devices.
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).
All of the above.

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

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

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

Which of the following statements concerning satellite EPIRBs is true?

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