§ 01 Specifications

The TX2501-AJS-4CH-DPA is a compact integrated dual-protection terminal — anti-jamming and anti-spoofing — for civil UAV and professional users. It supports dual-frequency BeiDou-3 GPS L1, Galileo E1 and BDS B1i reception, wideband jamming suppression against up to 3 jammers, and spoofing rejection with residual spoofing signal CN0 held to ≤20 dB at the output. Antenna array, anti-jamming module and GNSS receiver are integrated in a small, light, low-cost housing.

Interference types suppressed: band-limited Gaussian white noise, spread-spectrum matched-spectrum interference, pulsed, swept-frequency and mixed interference. Suppression coverage: azimuth 0—360°, elevation −90° to +90°.
