AWSG — Resilient PNT Threat Emulation — K9 Electronics Ltd

Professional GNSS waveform generation. Two form factors.

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.

Your constellation simulator leaves a critical gap

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.

Current test methodology
Static CW tone — single direction
Algorithm converges once, holds indefinitely. No AGC stress. No degree-of-freedom exhaustion. No convergence window exploitation. Null depth figure looks excellent on a datasheet.
Operational reality
Frequency-agile, non-stationary interference
Waveforms that change faster than convergence time. Signals that appear to arrive from multiple directions simultaneously. Amplitude variation that hunts AGC circuits. The algorithm is never given a stable problem to solve.
AWSG addresses this
Intelligent algorithm stress-testing
Eight distinct threat modes. Sub-millisecond profile switching. Four independent channels. Works alongside your existing constellation simulator — not instead of it. The only portable system designed specifically to stress adaptive beamforming algorithms.

Eight threat modes. Two form factors.

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.

MODE 01
Non-Stationary Random
Pseudo-random frequency hops with varying dwell times and amplitude. Non-stationary statistics that prevent covariance matrix convergence and hunt AGC continuously.
MODE 02
Fast Wideband Sweep
Rapidly sweeping frequency waveform that outpaces adaptive algorithm convergence windows. The null forms on where the interference was — not where it is.
MODE 03
Multi-Tone Generation
Simultaneous multiple frequency generation creating apparent spatial sources that consume null degrees-of-freedom budget. Exhausts a 4-element CRPA's nulling capacity from a single transmitter.
MODE 04
Chirp / Linear Ramp
Linear frequency ramp generating Doppler-like signatures that confuse direction-of-arrival estimators. Particularly effective against STAP and SFAP algorithm implementations.
MODE 05
Burst / Amplitude Pulsing
Sub-millisecond on/off amplitude patterns creating AGC hunting transients during which beamforming weight calculations are corrupted. Effective null depth degradation without power increase.
MODE 06
Programmable Mode Switching
Rapid switching between modes at intervals shorter than CRPA convergence time. Contrast-scored transition matrix ensures consecutive modes are maximally statistically distinct — the algorithm is always reconverging, never stabilising.
MODE 07
Pattern / Sequence
Pre-programmed waveform sequences from a configurable library. Enables repeatable, documented test scenarios — load the same pattern across multiple test sessions for consistent, comparable results.
MODE 08
Auto-Switch
Fully autonomous mode cycling driven by a contrast-scored transition matrix. Each consecutive mode is selected to maximise statistical difference from the previous — the adaptive algorithm is never given the same problem twice.

Two variants. One architecture.

Combined Deployment

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.

Already have a constellation simulator? This is what it's missing.

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.

Already using a constellation simulator?

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.
