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

Correct Answer: Option D — All of these

The COSPAS-SARSAT system utilizes low-earth orbit satellites to detect 406 MHz EPIRB signals. These satellites measure the Doppler shift to calculate position, time-tag the data, and relay the unique EPIRB identification number to Local User Terminals, which then retrieve vessel information from the international registration database.
