TX2501-AJS-4CH-DPA
Dual-frequency anti-jamming GNSS antenna for UAVs
The Miniaturized Dual Anti-jamming Integrated Unit is a compact satellite navigation anti-jamming and anti-spoofing device designed for civilian UAVs and industrial applications. It supports dual-frequency signal reception (GPS L1 and BDS B1I) and is compatible with the BeiDou-3 system. The device features broadband anti-jamming capabilities, simultaneously resisting up to three jammers, and provides anti-spoofing functionality. It integrates the antenna array, anti-jamming module, and GNSS receiver into a single device, characterized by its miniaturization, light weight, and low cost.
