AWSG Field
Four-channel rugged GNSS waveform generator for multi-channel CRPA and anti-jam development testing.
Product overview
Designed for controlled CRPA and anti-jamming development testing across 1100-1650 MHz. AWSG provides repeatable waveform profiles for engineering evaluation and is intended to complement established laboratory, chamber, wavefront and formal qualification methods.
Multi-channel capability: The Field system provides four independently configurable conducted waveform channels. They are not phase-coherent spatial wavefront channels and are not presented as an angle-of-arrival simulator.
Preliminary specifications
Waveform profiles
Non-Stationary Random
Pseudo-random variation of waveform parameters provides a repeatable stimulus for evaluating CRPA behaviour when interference statistics change with time.
Fast Wideband Sweep
Rapid swept-frequency operation provides a controlled test of response to changing spectral occupancy.
CW Tone
A stable single-frequency reference condition for baseline measurements and direct A/B comparison with time-varying profiles.
Linear Ramp
Controlled frequency evolution for characterising system behaviour under a repeatable time-varying spectral condition.
Adaptive Cycling
Automated transitions between defined waveform profiles for repeatable evaluation as the character of the interference changes.
Two-sub-band time-domain testing
In supported configurations, AWSG can alternate interference activity between the lower GNSS cluster (approximately 1176–1268 MHz) and upper GNSS cluster (approximately 1561–1606 MHz) using configurable short dwell intervals. This adds controlled time-varying spectral location as a test variable alongside waveform-profile changes. The resulting CRPA response is measured experimentally; no particular convergence or rejection outcome is assumed.
Applications
Suitable for CRPA algorithm development, anti-jam antenna integration, GNSS resilience engineering, bench evaluation and platform-level development testing for authorised defence, government and defence-industry programmes.
