Design and realization an ELT beacon and decoders of frames 406 MHz

摘要

COSPAS-SARSAT system which consists of space segment and ground segment provides a distress alert and the position information for a distressed airplane with beacon equipment. Currently, COSPAS-SARSAT system it's low on the second generation of beacons because allows for the encoding of position data in the transmitted 406 MHz message, thus providing for quasi-real time alerts and position information through the GEOSAR service. This paper presents realization of a beacon ELT second generation 406 MHz for use in aerospace applications and detection and decoding of frames sent. Also, performance is presented through the experience.
