Core Anti-Jamming Technology
Our anti-jamming solutions are built on Controlled Reception Pattern Array (CRPA) architecture and adaptive spatial filtering techniques. By combining multi-element array processing with interference suppression algorithms, the system can place deep nulls toward jamming sources while preserving reception of legitimate GNSS signals. This enables more resilient positioning and timing performance for UAV, UGV, and other mission-critical platforms operating in contested RF environments.
Adaptive Nulling Steering
Uses real-time adaptive spatial processing to form deep nulls toward interference sources and improve GNSS resilience in contested environments.
Multi-source Interference Mitigation
Supports effective mitigation of multiple jamming sources through array-based signal processing and anti-jamming control.
Compact System Integration
Supports low-SWaP integration for space-constrained platforms, with product paths that may include RF optimization and embedded GNSS receiver functionality.

Adaptive Null-Steering Against Multi-Source Jamming
The 4-element CRPA array dynamically identifies jamming signals and creates “Deep Nulls” in their direction. Even with multiple or mirrored jammers, the antenna maintains a high-gain beam toward GNSS satellites, ensuring uninterrupted PNT (Position, Navigation, and Timing) in contested environments.
