Highly Reliable GNSS Anti Jamming Navigation Module 8 Channel Anti Spoof For Defence
Product Details
8 Channel Anti Jamming Navigation Module
,8 Channel Anti Jamming Navigation Module
,Defence Grade Anti Jamming Module
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.
This module is a compact, high-performance anti-jamming and anti-spoofing GNSS module designed for UAVs, loitering munitions, vehicles, and maritime platforms. It integrates an advanced anti-jamming antenna array, interference suppression module, and a spoofing-resistant GNSS receiver, ensuring reliable positioning even in contested electromagnetic environments.
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.
