Key facts

  • Emulation of instrument landing system (ILS)
  • Emulation of VHF omnidirectional radio range (VOR)
  • Emulation of distance measuring equipment (DME)
  • Emulation of ground-based augmentation systems (GBAS)

Testing flight navigation receivers

Traditional ground-based flight navigation aids such as VOR, DME or ILS still play an important role in enroute navigation, precision approaches and landings. Landings can also be performed using satellite-based navigation in combination with differential corrections from local ground-based augmentation systems (GBAS). Onboard navigation receivers that use these technologies need to be tested under controlled and repeatable conditions. Rohde & Schwarz offers various solutions that generate signals for such navigation flight systems.

Features & benefits

Test like it's real

Avionics receiver testing under realistic conditions

Avionics test solutions from Rohde & Schwarz allow avionics receivers to be exposed to a realistic signal environment, i.e. to signal reception conditions that are very similar to those for a receiver onboard a plane. A combined GPS/GBAS simulation generates GBAS messages based on differential corrections consistent with the simulated GNSS errors. This enables advanced multimode receiver testing.
