📌 Overview
The High-Power GNSS Anti-Jamming Module is an advanced satellite navigation protection system designed to ensure reliable positioning, navigation, and timing (PNT) for drones, unmanned vehicles, and industrial platforms operating under complex electromagnetic conditions.
This module effectively shields user terminals from unintentional interference and deliberate signal attacks, ensuring stable navigation performance and operational safety for mission-critical applications.
With support for dual-frequency signal reception (1575.42 MHz / 1268.52 MHz) and a robust anti-jamming algorithm, it delivers superior interference suppression and wide-area coverage for GNSS-based systems.
⚡ Key Features

🎯 Performance & Application
This system is engineered for environments where GNSS interference, spoofing, or jamming severely impacts UAV and UGV navigation.
In field tests, the module maintains over 20 satellite locks under high-power interference, while standard receivers lose tracking completely. Its precise anti-jamming algorithms allow continuous, stable flight and positioning, making it ideal for:
-
Industrial drones operating near urban RF sources
-
Unmanned ground vehicles (UGVs) for defense or logistics
-
Surveying and mapping platforms in high-interference zones
-
Critical communication and infrastructure monitoring systems
