Abstract
Survival radio interrogator (1) transmits upon request a message including an identification of survival radio (3). Upon receiving and processing this message, survival radio (3) determines its position from the Global Positioning System and transmits a message back to the search aircraft (2) with the survival radio interrogator (1). The processor (10) of the survival radio interrogator 1 determines a range and bearing of the survival radio (3) and processes data from the survival radio 3 which data includes identification, position and messaging information for display on the LCD display 14. All message transmissions are conducted via the aircraft's (2) radio/intercom system (30).
