4 Channel Global Navigation Satellite System GNSS Anti-Jamming System
Product introduction
The product guarantees that satellite navigation data is not disturbed, including GPS, China Beidou, European Galileo and Russian Glonass. The anti-interference modules can all receive satellite signals, and main purpose of the module is to counteract the threat of interference guns and radar, ensuring that the navigation data of drones is not compromised interference, without losing position and yaw.
- This anti-interference system is designed to receive, amplify, down-convert, filter and perform anti interference processing on the BDS_B1 , GPS_L1 frequency signals of 4 channels.
- It operates at a voltage of 5V~12V and consists of 4 main components:the antenna array ,the RF component ,the anti - interference processing component ,the receiver.
- It can resist 3 broadband interference sources and provide high-precision positioning and accurate timing under strong interference conditions.
Key Applications
1. UAVs & Drones – Maintains stable GNSS positioning in urban or RF‑crowded airspace, even with multiple jammers active, ensuring safe autonomous flight.
2. Militar*y Vehicles & Tactical Systems – Protects against intentional GPS/GLONASS jamming in electronic warfare, delivering uninterrupted navigation for ground and airborne platforms.
3. Marine & Offshore Navigation – Counters interference from shipboard radar and satellite comms, providing reliable heading and timing for dynamic positioning at sea.
4. Critical Infrastructure (Power/Telecom) – Guards 1PPS synchronisation signals against accidental or malicious jamming, preserving grid stability and network timing accuracy.

Highly Reliable 8 Channel Anti Spoof For Defence GNSS Anti Jamming Navigation Module
What is GPS/GNSS jamming? 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. What is Anti Jamming GNSS Systems? Anti ... -
