Feature Spotlight: OSPREY GPS Simulation Advantages
Designed with flexibility and efficiency in mind, the OSPREY GPS Simulator delivers advanced features that streamline avionics testing and training. From mobile control to real-time route simulation, these capabilities help reduce flight time, speed up validation, and ensure dependable GPS performance across a range of applications.
Real-Time GPS Simulation

OSPREY enables live simulation of both static positions and dynamic flight routes, allowing avionics teams to verify GPS device behavior without leaving the hangar. This is essential for testing new installations, troubleshooting signal inconsistencies, or replicating in-flight scenarios safely on the ground. With 18-channel signal generation on the L1 band, it provides reliable coverage for a wide range of test cases — from basic positioning to complex navigational assessments.
Remote App Interface

The OSPREY simulator includes an intuitive mobile control interface, available for both iOS and Android devices. This remote functionality empowers technicians and engineers to manage simulations, configure settings, and trigger tests without returning to the control station, ideal for time-sensitive testing and on-the-fly adjustments. It's a productivity booster for field teams and lab environments alike.
Full Avionics Support

OSPREY is compatible with global avionics test sets and workflows, making it a seamless addition to any aircraft maintenance or system certification program. Whether you're working with commercial fleets, military platforms, or civil aviation trainers, OSPREY adapts to a broad range of test needs — including ADS-B testing, antenna placement validation, and navigation system checks.
Daily Almanac Automation

To reduce lock-on time and ensure accuracy, OSPREY allows for automated upload of the current GPS Almanac. This feature eliminates the need for manual entry or outdated ephemeris data, ensuring that GPS receivers acquire signals more quickly and reliably. It’s especially useful in high-throughput environments where multiple units or frequent tests are being conducted.
