Portable Navigation Signal Module 4 7 13 22 Channel Multi Mode Guidance GNSS Spoofing 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.

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

Designed for mission-critical applications, the GNSS Anti-Jamming Navigation Kit provides resilient navigation capability in environments where conventional GNSS receivers would fail. The system integrates an 8-channel array antenna, a dedicated anti-jamming unit and a high-performance GNSS positioning module into a single, compact solution. This architecture allows the kit to maintain continuous positioning while actively countering multiple simultaneous interference sources.

The array antenna covers the primary civil GNSS frequency bands — B1I/B1C, L1 C/A, E1 and G1 — and is capable of receiving signals across eight independent channels. It can simultaneously suppress up to seven interference sources of various types, including narrowband, broadband, pulsed, swept-frequency and hybrid interference. This multi-source suppression capability significantly enhances the system’s operational reliability in complex electromagnetic scenarios.

At the core of the system is a multi-domain anti-jamming algorithm that processes signals across polarization, spatial, temporal and frequency domains. By combining these complementary dimensions, the algorithm delivers strong interference rejection while preserving the integrity of the authentic satellite signals. The GNSS positioning unit further supports multi-constellation and multi-frequency signal processing, ensuring high sensitivity and accurate positioning performance. The overall system is optimized for dynamic platforms and outputs real-time, highly reliable PNT data suitable for integration into a wide range of operational systems.

The products are widely used in satellite communication, UAV, surveying and mapping, intelligent driving and other fields.

GNSS spoofing is a silent but serious threat. Spoofing can silently manipulate positioning and timing without triggering alarms, creating serious risks for autonomous systems, infrastructure, and safety-critical operations.

This provides built-in anti-spoofing and anti-jamming protection designed to detect and mitigate these threats in real-time. By combining signal authentication, advanced consistency and plausibility checks, and multi-frequency, multi-constellation resilience, helps ensure secure, reliable, and trustworthy GNSS positioning and timing, even in the presence of sophisticated spoofing.
