[Avionics Today 08-06-2015] Rockwell Collins has introduced its new DF-500 Direction Finder for Search and Rescue (SAR) missions. The system pinpoints distress signals and enables aircraft to receive and immediately locate activated 406 MHz Emergency Position-Indicating Radio Beacon (EPIRB) signals, allowing crews to go directly to people in distress.

“When it comes to airborne SAR missions, saving time is often the difference between a rescue and a recovery,” said Troy Brunk, vice president and general manager of airborne solutions for Rockwell Collins.

The DF-500 direction finder replaces the DF-430, which serves government and military SAR operators. Software-defined radio technology developed for the DF-500 enables higher sensitivity, immunity to interferences and stability of bearing indications, according to Rockwell Collins.
