VRS-5910™ SERIES

The VRS-5910™ repeater system provides UAV operators with a turn-key, COTS/NDI solution for maintaining a reliable, frequency agile, two-way voice communication link with air traffic controllers (ATC) during extended range and duration flights.
 

The VRS 5910™ relay package features remote frequency control through any ground based computer, full VHF commercial band coverage, (118.000 MHz to 135.975 MHz with 25 KHz channel spacing) and 20/40/100/200 Watts of transmit power for long range, reliable operation. UHF and VHF/UHF coverage is optional.
 

The Remote Frequency Control feature allow the user to select both the forward and return link frequencies (pilot to aircraft and aircraft to ATC) wirelessly, through any RS-232 or RS-422 serial port interface using simple ASCII commands. The frequency control link can be either an existing user supplied communications up-link or Aero Telemetry's DLS-1000 Series™, long range, software programmable wireless data link system. Call for details.
