RT-500-M SAR Direction Finder System
for Rescue Missions at Sea
The RT-500-M is a multi-band direction finder
system that operates on all frequency bands used
for rescue missions. This direction finder automatically
monitors the emergency frequencies 121.500 MHz,
243.000 MHz and 406.028 MHz (Cospas-Sarsat) as
well as channel 16 of the marine band. The bright
TFT display permits a clear overview of all direction
finder information and operating parameters. A
convenient menu structure makes it possible to
adapt the RT-500-M direction finder system to
the needs of the user. Various interfaces (LAN,
NMEA RS-422, RS-232) facilitate integration of
the direction finder system in legacy or planned
system environments.
Applications
The RT-500-M direction finder system fully meets
the steadily increasing needs of modern civilian
and military search-and-rescue organizations.
Emergency beacons that operate on the 406.028
MHz Cospas-Sarsat frequency can be reliably identified
and localized. Like all RHOTHETA direction finder
systems, the RT-500-M features complete MOB functionality
to ensure the safety of SAR crew members. That
makes the RT-500-M direction finder system a complete
solution for professional SAR organizations.
Although the RT-500-M was optimized for use in
high sea states, this direction finder system
is also suitable for stationary VTS applications.
