A Soviet/Russian short-range radio navigation system broadly comparable in purpose to TACAN/VOR-DME, used to provide aircraft with navigation information relative to a ground station.

Key characteristics:

  • Military navigation aid: Common on Soviet-era aircraft for enroute navigation and approach guidance.
  • Station-based: Aircraft tune/select an RSBN channel/station to receive navigation information.
  • Provides usable nav cues: Depending on aircraft/system implementation, RSBN can support:
    • Bearing/course guidance to/from a station (similar “work” to VOR/TACAN course tracking)
    • Range information (functionally like DME) in many implementations
  • Often paired conceptually with landing systems: In Soviet doctrine, RSBN is commonly associated with approach/landing support ecosystems (with separate components providing glidepath/localizer equivalents depending on the airfield/system).

Application in DCS World

  • RSBN is modeled on certain Soviet-era DCS aircraft and maps/airfields that support it (especially aircraft like the MiG-21bis and others with RSBN/PRMG-style equipment).
  • In training terms, cadets can use RSBN to practice the same core skills you’d practice with TACAN/VOR-DME:
    • Intercepting and tracking courses
    • Flying station-based navigation legs
    • Using range information for step-downs, timing, and situational awareness
  • Coverage and station availability are mission/map dependent, so RSBN training is best done in missions designed with known RSBN stations and clear objectives.
