SAT406M - An EGNSS application providing an end-to-end solution based on the SAR/Galileo service and particularly using the Return-Link-Message (RLM), to improve the mobility and safety of citizens

The proposal aims at developing and promoting an EGNSS application providing an end-to-end solution based on the SAR/Galileo service, particularly using the unique Return-Link-Message (RLM), to improve the Search and Rescue of people in distress, comprising:

• An improved Personal Locator Beacon (PLB): wrist-worn, integrating a 406MHz Cospas-Sarsat compatible beacon and a Digital Selective Calling (DSC) transceiver compatible with marine VHF radios.
• A new communication method enhancing the standard communication between the PLB and the SAR/Galileo system, using an innovative uplink solution compatible with Cospas-Sarsat standards, and Galileo Return Link downlink.

A specific application of the new communication method: monitoring the physiological status of the PLB user and communicating it to the SAR system on the uplink, then upon RLM receive on downlink, further use that method to assist the rescue operation.
