SDR-OMNI GPS APP
SDR-OMNI GPS Simulator Application
The SDR-OMNI GPS Simulator Application expands both the commercial SDR-OMNI and SDR-OMNI/MIL platforms into a portable GPS test solution for flight line, hangar, installation, and maintenance environments.
Using a controlled GPS antenna coupler and multi-satellite GPS L1 simulation, technicians can verify GPS receiver operation, support ADS-B installations, test coupled autopilot functions, and troubleshoot antenna or cable issues without relying on live sky conditions.
Compatible with both SDR-OMNI and SDR-OMNI/MIL platforms.
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.
Tel-Instrument Expands SDR-OMNI with New GPS Simulator Application
Tel-Instrument Electronics Corp. is pleased to announce the availability of the new SDR-OMNI GPS Simulator Application, a powerful expansion to the SDR-OMNI platform that brings practical GPS receiver, ADS-B, and coupled autopilot testing directly into the hangar and onto the flight line.Designed for aircraft maintenance, avionics troubleshooting, and installation support, the SDR-OMNI GPS Simulator Application transforms SDR-OMNI into a portable GPS test solution capable of simulating up to 12 GPS L1 satellite channels in a controlled aircraft-on-ground environment. Using a dedicated GPS antenna coupler and multi-satellite L1 simulation, technicians can verify GPS receiver operation, support ADS-B position source validation, test coupled autopilot functions, and troubleshoot antenna or coax issues without relying on live sky conditions.
