7-A-042: SART: Testing Procedures & Battery Parameters

7-42F1: Which is not a function of satellite under COSPAS-SARSAT using satellite EPIRBs?

After the EPIRB's position is calculated using the Doppler shift COSPAS-SARSAT satellites provide follow-on SAR communications.

Relayed satellite message includes the EPIRB ID number which provides a reference for retrieval of vessel information for the shore database.

Doppler shift of EPIRB signal is measured and the EPIRB's position is calculated.

Information received from EPIRBs is time-tagged and transmitted to any Local User Terminal in the satellite's view.



7-42F2: Which of the following satellite systems is of particular & dedicated importance to search and rescue missions under GMDSS?

COSPAS/SARSAT

Inmarsat

GPS

Iridium



7-42F3: Which of the following statements concerning COSPAS-SARSAT is false?

Doppler frequency measurements provide more precise locations than GPIRB signals.

406 MHz EPIRBS are units that are used as alerting devices.

The Doppler frequency measurement concept is used to determine the EPIRB's location.

Satellites in a low-earth polar orbit detect EPIRB beacons on 406 MHz and relay the information to a Local User Terminal (LUT).



7-42F4: Which of the following statements concerning COSPAS-SARSAT is false?

After initiating a call request and selecting the LES, these satellites may be used for commercial messages.

EPIRBS, ELTs, and PLBs use the system primarily for Distress alerting.

These satellites monitor 406 MHz for EPIRB signals.

These satellites use Doppler shift measurement to determine the location of the beacons.



7-42F5: Which of the following statements concerning the EPIRB system is true?

The Inmarsat system will not provide alerts and position report for 406 MHz EPIRBs equipped ith GPS receivers.

GOES weather satellites willprovide alerting with complete worldwide coverage.

COSPAS-SARSAT satellites always provides an alert and position report within 10 minutes of reception.

The GPS satellite system will replay an alert and position report within 20 minutes of reception.



7-42F6: Which of the following statements concerning satellite EPIRBs is true?

Once activated, these EPIRBs transmit a signal for use in identifying the vessel and for determining the position of the beacon.

The coded EPIRB signal identifies the nature of the Distress situation.

The coded EPIRB 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.
