Anti-interference & Anti-Spoofing Antennas: How They Defend GNSS Signals

2025-12-19 15:52

Electronic interference has an increasingly significant impact on unmanned devices. Generally speaking, UAVs operate through flight control, image transmission, and GNSS.

Meanwhile, technologies such as frequency hopping, spread spectrum, and hidden frequency points are used to prevent interfering frequency bands from matching those of UAVs.

However, image transmission and flight control protocols can be easily crackedand GNSS links can be interference with or have their positioning altered by spoofing devices.

Currently, electronic interference capabilities are becoming increasingly powerful, affecting everything from small FPV systems to UAVs and unmanned boats.

Infox has offered a new solution to this problem.


When interference waves arrive, multi-array antennas work in conjunction with Infox's algorithmic system, to eliminate interference and spoofing, and enhance GNSS signals. Thus, even in the face of extremely powerful interference devices, unmanned devices can still complete tasks relying on GNSS signals.

Currently, Infox's products have achieved a 100% test success rate.
