Standard CRPA test methodologies use static CW tones from a single direction. Resilient PNT demands more. AWSG is a phase-coherent multi-channel RF generator producing GNSS waveform generation waveforms that expose the true performance envelope of any CRPA or adaptive anti-jam system — dynamic nulling verification at a fraction of the cost of constellation simulators.
GNSS constellation simulators — including software-defined platforms combined with vector signal generators — generate defined, repeatable interference scenarios. That is exactly what makes them excellent for satellite signal fidelity testing, and exactly what makes them insufficient for CRPA algorithm stress-testing.
Convergence time windows, degrees-of-freedom exhaustion, covariance stationarity assumptions, AGC hunting — none of these vulnerabilities are exposed by a defined CW tone or AWGN source from a known direction. Your CRPA datasheet null depth was almost certainly measured against precisely that scenario.
If your CRPA was validated using a constellation simulator's built-in interference generator, you know how it performs against a defined threat. AWSG tells you how it performs against an intelligent one.
Both AWSG variants share the same five confirmed waveform profiles. Each targets a distinct vulnerability in CRPA adaptive processing — deployable from a rugged case system or a pocket-sized machined aluminium unit.
1× AWSG Field + 2× AWSG Compact creates a 6-channel distributed GNSS waveform generation capability. Four simultaneous modes from the Field unit plus one mode each from the Compact units at different spatial positions — each Compact pre-configured via laptop before deployment, operated standalone in the field.
Constellation simulators — whether software-defined with vector signal generator outputs, or wavefront systems — validate CRPA performance against known, defined interference. AWSG validates performance against intelligent, non-stationary threats that no constellation simulator interference library generates. The two are complementary. Most serious CRPA test programmes need both.

If you are using a software-defined GNSS simulator with a vector signal generator for CRPA testing, AWSG addresses the one scenario your existing setup cannot replicate — non-stationary, algorithm-stressing waveforms from a portable, field-deployable unit. Most CRPA test programmes require both. AWSG is the missing half.
