SDR-OMNI GPS Simulator Application
Bring GPS Receiver, ADS-B, and Autopilot Testing Into the Hangar
Part Number: 90 000 210
Designed for practical aircraft-on-ground testing, the SDR-OMNI GPS Simulator provides a controlled and repeatable GPS signal environment for troubleshooting, installation verification, and return-to-service validation. Whether performing routine receiver checks, ADS-B position source verification, or autopilot system validation, the GPS application adds another critical avionics capability to the SDR-OMNI platform.
Features
Key Features
12-Channel GPS L1 Satellite Simulation
Simulates up to 12 GPS L1 satellite channels to support realistic receiver acquisition, stable 3D position solutions, and repeatable aircraft-on-ground testing.Flight Line and Hangar Ready
Supports GPS receiver checks, ADS-B position source validation, and coupled autopilot testing directly on the aircraft without dependence on live sky visibility.Controlled Signal Application
Uses a dedicated GPS antenna coupler and RF cable assembly to support contained GPS simulation and minimize unwanted signal leakage during ground testing.Static or Straight-Line Motion Simulation
Allows technicians to simulate either a stationary aircraft position or a continuous straight-line flight profile with adjustable altitude, bearing, ground speed, and vertical speed.Remote Operation
GPS simulation setup and test functions can be controlled from a connected mobile device or tablet for convenient operation in the hangar or on the flight line.
Intuitive Touch Interface
A graphical touchscreen interface provides fast setup, clear satellite geometry visualization, and straightforward operation without complex menu navigation.
Expandable for Multiple Antenna Installations
Supports a range of aircraft GPS installation scenarios and can be adapted for more complex antenna configurations as required.
