Based on the proven Skydel simulator, Orolia offers two flexible solutions for testing CRPA: GSG Wavefront and GSG Anechoic. Skydel based GNSS simulators tailored for custom projects and R&D needs are also available.
Wavefront GNSS Simulator
GSG Wavefront combines high performance with Skydel Advanced Jammers to enable unlimited test scenarios. It leverages the multi-instance synchronization features of Skydel to enable simulation scenarios including high-dynamics trajectories (GNSS and non-GNSS). GSG Wavefront generates phase-synchronized signals in real time, to realistically simulate the behavior of a CRPA antenna.
GSG Wavefront features:
- High Performance (Accurate phase synchronization under 1º RMS)
- 8+ antenna elements
- Large number of dynamic transmitters + user-defined waveforms (via Advanced Jamming)
Use GSG Wavefront for:
- Tests scenarios integrating both dynamic receiver and interferences positions
- Lab installations where an anechoic chamber is not practical
- Testing a CRPA processing unit (without antenna)
Simulate the behavior of a CRPA antenna with GSG Wavefront, upward of 8 antenna elements.
Anechoic Chamber GNSS Simulator
Orolia’s GSG Anechoic is a complete system featuring the Skydel simulation engine, advanced calibration tools and full hardware. GSG Anechoic is designed to speed up chamber calibration setup and reduce the multiplication of hardware systems.
Based on COTS hardware, it supports 32+ RF outputs to provide a cost-effective CRPA testing solution for RF labs equipped with an anechoic chamber.
GSG Anechoic configurations feature:
- Up to 32 RF Outputs
- Automatic Antenna Mapping
- Automatic Time Delay Calibration
- Automatic Power Loss Calibration
- Support for GPS encrypted codes, via BroadSim Anechoic
- Very high jamming power (>110 dB of J/S)
Use GSG Anechoic for:
- Comprehensive testing, including the antenna
- Testing unlimited numbers of antenna elements
- Testing static positions
Adaptive antennas, also called CRPA, or sometimes anti-jam antennas, will play a greater role in the future GPS/GNSS landscape. Their unique capabilities help increase resilience to GNSS signals impairments, such as ever-increasing multipath, accidental interferences, or even RF attacks. Once reserved solely for the military domain, adaptive antennas are entering the civilian market and are poised to bring their benefits to the fields of aerospace, ground transportation, and autonomous driving, as well as various others.
Engineers working with GNSS systems that employ CRPAs and multi-element antennas need special test systems since they need to replicate very specific test conditions that are impossible with live signals. We created GSG Wavefront and GSG Anechoic to address those needs. Like all other GSG configurations, a CRPA simulator based on GSG provides COTS hardware benefits: configuration flexibility and cost-effectiveness.
Anti-Jam antennas use techniques, such as nulling or beam-forming, to mitigate the effects of interfering signals.
