This compact satellite signal anti-interference system is specifically engineered for unmanned platforms to enhance the safety of PNT (Positioning, Navigation, and Timing) foundational data.
The anti-jamming system with a built-in positioning module is capable of receiving satellite signals, primarily serving to negate threats from jamming guns and interference radars, ensuring that the navigation data of UAVs remains uncorrupted, preserving accurate positioning and heading.
The anti-interference system integrates 4 satellite antennas, a positioning module, and an anti-interference module to directly supply satellite navigation data to the UAV flight control system. It operates on dual-frequency points, allowing for the selection of any two from the B1/L1, L2, and B3 bands (B1/L1, B3 frequency by default).
Features:
Dual-frequency point anti-interference capabilities, covering both 1.2 GHz and 1.5 GHz bands
