LOCATING DOWNED AIRCRAFT BY GRAN (GLOBAL RESCUE ALARM NET)

This paper describes a worldwide distress alarm, identification, and position location system which could be operational within three years. The Global Rescue Alarm Net (GRAN) feasibility tests conducted by the Naval Air Test Center utilized a NASA Omega Position Locating Equipment (OPLE) package modified for UHF operation. Results of low power (ERP) tests with four satellites are discussed. Follow-on tests already funded by a Navy/NASA/Coast Guard joint program to develop system specifications are described.
