Abstract
A dual-satellite emergency locator beacon including a first satellite communications transmitter, a second satellite communications transmitter, a first microprocessor and a second microprocessor. The first microprocessor controls the first transmitter and the second microprocessor controls the second transmitter. The first transmitter is configured to communicate over a first satellite communications system, such as the Cospas-Sarsat 406 MHz system, and the second transmitter is configured to communicate over a second satellite communications system, such as a commercial satellite communications system. The beacon includes a shared section comprising an antenna system comprising a first and second antenna, the first for the 406 Mhz transmitter and the second for the commercial satellite transmitter. The first and second microprocessors of the beacon are interconnected to permit data transfer between the two sections of the beacon.
