Wavefront GNSS Simulator
Skydel 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). Skydel Wavefront generates phase-synchronized signals in real time, to realistically simulate the behavior of a CRPA antenna.
Skydel 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 Skydel 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 Skydel Wavefront, upward of 8 antenna elements.

- Support for GPS encrypted codes, via BroadSim Anechoic
- Very high jamming power (>110 dB of J/S)
Use Skydel 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 Skydel Wavefront and Skydel Anechoic to address those needs. A CRPA simulator based on Skydel 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.

An Engineer’s Guide to CRPA TestingCRPAs (Controlled Reception Pattern Antennas) are becoming increasingly common, particularly in the Defense sector. CRPAs are an extremely effective anti-jam/spoof solution, because they adapt dynamically in response to jamming or spoofing signals. It is important to know the direction from which the interference is coming, so that you do not receive that RF power into your GPS receiver. This is done by forming nulls in the direction of the interference, or by using beam forming techniques to isolate and track only the true satellite signals, ignoring theothers. This guide discusses the applications and use cases for CRPAs, how they work and the methods for testing them. It also explores the various types of testing solutions available in the marketplace today, and helps you choose the right solution for your specific application. |
