Which is not a function of a satellite under COSPAS-SARSAT using satellite EPIRBs?

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

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