CRPA-TESTby K9 Electronics
ANTI-JAM TEST TECHNOLOGY — K9 ELECTRONICS LTD

Test GPS & GNSS anti-jamming antennas.

AWJ-TEST is a portable GNSS RF test platform for evaluating CRPA and adaptive anti-jam antenna systems. It gives antenna developers, system integrators and resilient-PNT teams a practical way to exercise anti-jamming performance during development and integration — without making “CRPA” the only route by which customers can find the technology.

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-window exhaustion, covariance stationarity assumptions, AGC hunting — none of these vulnerabilities are exposed by a defined CW tone or AWGN source from a known direction. Static CW and other defined interference cases are commonly used to establish baseline anti-jam performance.

If your CRPA was validated using a constellation simulator's built-in interference generator, you know how it performs against a defined threat. AWJ-TEST is intended to explore behaviour under changing, non-stationary interference conditions. Adaptive arrays have finite update and convergence behaviour. AWJ-TEST is intended to help engineering teams investigate that behaviour under repeatable changing conditions.

Current test methodology
Static CW tone — single direction
Algorithm converges once, holds indefinitely. No AGC stress. No convergence time 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.
AWJ-TEST addresses this
Intelligent algorithm stress-testing
5 confirmed waveform profiles. Sub-millisecond profile switching. Four independent channels. Works alongside your existing constellation simulator — not instead of it. Designed specifically as a portable development tool for stressing adaptive anti-jam processing.

5 confirmed profiles. Two form factors.

Both AWJ-TEST 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. Configurable non-stationary statistics intended to exercise covariance estimation and AGC behaviour.
MODE 02
Fast Wideband Sweep
Rapidly swept frequency profiles intended to evaluate adaptive response as interference conditions change.
MODE 03
CW Tone
Continuous wave single-frequency output at precisely controlled amplitude. Establishes baseline CRPA null convergence performance — the scenario most CRPA datasheets are measured against.
MODE 04
Linear Ramp
Linear frequency-ramp profiles for evaluating processing behaviour under controlled time-varying spectral conditions.
MODE 05
Adaptive Cycling
Automated profile cycling that changes waveform conditions between successive test intervals for repeatable stress-testing.

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.

Field + Compact. Flexible distributed testing.

Combine the four-channel AWSG Field system with one or more AWSG Compact units for distributed CRPA and anti-jam development testing across multiple spatial positions.

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. AWJ-TEST adds configurable non-stationary waveform profiles intended to complement the defined scenarios available in established GNSS test systems. The two are complementary. A layered CRPA test programme can use both approaches at different stages of development and validation.

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, convergence-time-attacking waveform profiles from a portable, field-deployable unit. Most CRPA test programmes require both. AWJ-TEST is intended to complement that existing laboratory capability.
