The Marconi IFR Aeroflex GPSG-1000 is a portable GPS/Galileo positional simulator engineered for validation and calibration of GPS receivers and navigation systems across aerospace, automotive, and telecommunications applications. This software-upgradable, single-carrier multi-channel platform generates simultaneous GPS and Galileo signals with WAAS/EGNOS SBAS simulation, supporting both static positioning and dynamic trajectory playback through waypoint entry or NMEA 0183 file import.
Technical Specifications
The simulator operates in 6 or 12 channel configurations with upgrade capability. GPS signal generation includes L1, L1C, L2C, and L5 bands. Galileo coverage spans E1, E5, E5a, E5b, and E6 signals. SBAS simulation supports WAAS/EGNOS on L1 and L5, with MSAS and GAGAN available. PRN assignments cover GPS PRN 1–32, Galileo PRN 1–36, and SBAS PRN 120–138.
The 6-channel configuration allocates five channels for RAIM operation and one for SBAS simulation. The 12-channel unit provides six additional channels enabling arbitrary Space Vehicle (SV) selection with mixed GPS/Galileo constellations. One or two channels can be dedicated to SBAS.
Individual SV parameters including Doppler, Amplitude, Step Error, Code Carrier Coherence, and Satellite Health are programmable and can be deviated from nominal values.
– Key Features
• Static 3D positioning via Latitude/Longitude/Height entry or waypoint database selection
• Dynamic simulation using multi-leg waypoint schemes with auto-calculated range rate and altitude rate
• Waypoint legs definable in LAT/LONG format with airport/city database recall
• Route creation, storage, and recall supporting single playback or continuous looping
• Realistic turn simulation to 10G
• NMEA 0183 file record and playback for dynamic trajectory scenarios
• Mixed GPS and Galileo satellite selection within all configurations
– Typical Applications
Aerospace receiver validation, automotive navigation system testing, telecommunications infrastructure GPS synchronization, and RAIM performance verification in multi-constellation environments.
– Compatibility & Integration
NMEA 0183 file format support enables integration with external navigation databases and flight planning tools. Waypoint-based trajectory definition and continuous looping modes accommodate diverse test scenarios from static positioning to dynamic flight path simulation.
