GMC's CRPA (Controlled Reception Pattern Antenna) delivers60 dB+ anti-jamming protection against GPS/GNSS jamming and spoofing attacks — engineered for UAVs operating in contested electromagnetic environments.
Our CRPA systems leverage advanced null-steering algorithms and multi-element phased arrays to neutralize jamming and spoofing threats in real time.
Dynamically forms deep nulls in the direction of jamming signals while maintaining gain toward legitimate GNSS satellites, achieving 60 dB+ interference suppression.
Multi-element spatial discrimination detects and rejects counterfeit satellite signals. Protects against sophisticated meaconing and replay attacks.
Simultaneous B3 (BeiDou) and B1 (GPS L1/GLONASS G1) band coverage ensures robust multi-constellation navigation resilience across all major GNSS systems.
Onboard digital signal processor executes adaptive beamforming algorithms with sub-millisecond latency, ensuring uninterrupted navigation during jamming events.
Ultra-compact form factor with minimal Size, Weight, and Power consumption — designed specifically for small to medium UAV platforms with strict payload budgets.
IP67-rated aluminum enclosure with conformal-coated PCBs withstands harsh environmental conditions including vibration, shock, rain, and extreme temperatures.
Our CRPA system uses a 4-element microstrip patch antenna array coupled with a high-speed digital signal processing unit. The adaptive beamformer continuously analyzes the spatial signature of incoming signals and adjusts element weights in real time to maximize gain toward satellites while nulling interference.
From compact 4-element arrays to full 9-element configurations for demanding mission profiles.
Lightweight CRPA optimized for small-to-medium UAVs. Provides 60 dB jamming suppression with minimal SWaP impact.
High-performance 9-element configuration for maximum jammer suppression in high-threat operational theaters.
Integrated GNSS receiver (Unicore UM620) with anti-jamming DSP on a single PCB for embedded applications.
Tailored antenna arrays with specialized frequency bands, form factors, and interface options for OEM integration.
ISO-certified production facilities with automated assembly and comprehensive RF testing for every unit shipped.
