The IX-4B3P is a compact integrated GNSS anti-jamming terminal for civil UAV and professional users. It receives BDS-B1C and GPS-L1 (plus Galileo-E1 on the B3 version), with a second band selected at order time — BeiDou B3 (IX-4B3P), GPS L2 (IX-4L2) or GPS L5 / Galileo E5 (IX-4L5) — so the terminal can be matched to the receiver already in the platform. It suppresses wideband interference across those bands and protects against up to 3 jammers, with the antenna array, anti-jamming module and GNSS receiver integrated in one 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°.
