GPS/GNSS jamming happens when weak satellite signals are disrupted by stronger radio signals on the same or nearby frequencies. Because GNSS signals travel from satellites far away in orbit, they are very weak and easy to overpower.
Anti jamming GNSS systems are advanced solutions designed to detect, suppress, and mitigate intentional or unintentional interference, ensuring reliable positioning, navigation, and timing even in highly contested environments. As GNSS disruptions become more frequent worldwide, these technologies have shifted to a critical component across defense, aviation, maritime, and autonomous systems.
GNSS Anti-Jamming Navigation Kit
The GNSS Anti-Jamming Navigation Kit consists of an array antenna, anti-jamming unit, and GNSS positioning unit.
The array antenna is capable of receiving signals across 8 channels covering the B1I/B1C/L1 C/A/E1/G1 frequency bands for anti-jamming processing. The system supports simultaneous suppression of interference across up to seven B1I/B1C/L1 C/A/E1/G1 interference sources while maintaining GNSS positioning capability.
Supported interference types include narrowband, broadband, pulsed, swept-frequency, and combined interference.
The anti-jamming unit incorporates a polarization-, spatial-, temporal-, and frequency-domain anti-jamming processing algorithm. By integrating multidimensional characteristics across polarization, spatial, time, and frequency domains, the system provides effective suppression against various forms of GNSS interference.
The GNSS positioning unit supports the reception, decoding, and processing of multi-constellation and multi-frequency satellite signals, providing high sensitivity and high-accuracy positioning performance.
The overall system is designed to maintain stable operation in dynamic environments while providing strong anti-jamming performance under complex electromagnetic conditions. It outputs real-time, highly reliable PNT (Position, Navigation and Timing) information and can be integrated into various platforms requiring reliable navigation and positioning in challenging operational environments.
