Rockwell Collins introduces DF-500
Rockwell Collins has introduced its new DF-500 direction finder system, designed to efficiently pinpoint distress signals and enable search and rescue (SAR) aircraft to receive and locate Emergency Position-Indicating Radio Beacon (EPIRB) signals.
The DF-500 succeeds the older-generation DF-430 direction finder, which is used by government and military SAR operators. The DF-500 is backwards compatible with the DF-430 and has a solid-state antenna that can be added to the mounting provisions of the DF-301E direction finding antenna system.
The system features software-defined radio technology for higher sensitivity, stability of bearing indications and immunity to interferences. It has new features, such as multi-channel scanning and real-time monitoring, fast scanning and interoperability with automatic identification system and maritime digital selective calling distress protocols. Its multi-channel architecture allows it to simultaneously monitor key frequencies and detect V/UHF radio distress/safety calls or emergency beacons.
Troy Brunk, vice president and general manager, airborne solutions, Rockwell Collins, said: 'When it comes to airborne SAR missions, saving time is often the difference between a rescue and a recovery. That's why civilian, government and military SAR organisations are upgrading their aircraft's direction-finder capabilities with Rockwell Collins' DF-500 direction finder.'
