Test and Evaluation of the Satellite-Aided Maritime Search and Rescue System (SAMSARS). Volume 2. Hardware Circuitry and Software Programs

摘要

SAMSARS includes a float-free Emergency Position-Indicating Radio Beacon (EPIRB) buoy with 1 to 5 watts of output power. Distress information is translated into a spread spectrum signal. The SAMSARS EPIRB signal is designed to be relayed through a maritime commercial satellite (INMARSAT) to a coast earth station. There the signal is processed in the SAMSARS receiver to recover message data. This part of the report, Volume 2, contains four appendices to the main body of the SAMSARS Final Report, Volume 1. These appendices elaborate the calculations of the SAMSARS system performance, provide detailed description of SAMSARS hardware circuitry and software programs, and delineate the receiver/processor operating instructions.
