Main Features of Virtual Radar Server:

• Real-Time Aircraft Tracking:
  VRS allows users to track real aircraft by connecting to a Mode-S receiver capable of receiving ADS-B transmissions. It is compatible with devices like Kinetic Avionics' SBS-1er and SBS-3 radios, as well as any receiver or SDR that produces formats such as Kinetic text message, AVR, or Mode-S Beast binary.

• Flight Simulator Integration:
  VRS can display the positions of simulated aircraft from Microsoft Flight Simulator X, Microsoft Flight Simulator 2020, and X-Plane. By installing VRS on the same computer running the flight simulator, users can visualize simulated flights without needing a Mode-S receiver.
