7-Element CRPA Antenna for GNSS Anti-Jamming
All four constellations, up to 6 simultaneous jammers suppressed
- Array elements
- 7
- Max jammers
- 6
- Weight
- ≤1200 g
A compact seven-element integrated anti-jamming terminal for multi-constellation GNSS, aimed at civil UAV and professional users. It receives BDS-B1, GPS-L1, GLONASS-G1 and Galileo-E1, suppresses wideband interference and protects against up to 6 jammers. The antenna array, anti-jamming module and GNSS receiver are fully integrated, keeping the unit small, light and cost-effective.
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°.

TX2504 anti-jamming antenna test in a city centre
Field test of the TX2504, a 7-element CRPA antenna that can null up to six jammers. With a jammer switched on across a city square, signal levels dip but the satellites stay in track and the position holds: anti-jamming antenna performance in a dense urban environment.
The plot below is locked to this model's array. Drag a jammer to see where the nulls form and which satellites stay locked.
