The TX-S65-4CH-SNB is an ultra-compact integrated anti-jamming antenna terminal with a 65 mm aperture. It integrates the antenna array, anti-jamming module and GNSS receiver in a single housing, delivering wideband jamming suppression and positioning on the B1/L1 bands, with Galileo E1 alongside GPS L1. Designed for industries that need a small, light and low-cost solution, such as small and medium unmanned aerial vehicles.
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°.

TX-S65 CRPA antenna jamming test in the city
Field test of the TX-S65, a 4-element CRPA antenna (controlled reception pattern antenna) for small drones. With a GPS jammer about 10 m away in a dense city, the receiver keeps tracking BeiDou, GPS and Galileo satellites and the position holds from jammer on to jammer off: GPS anti-jamming you can see on screen.
The plot below is locked to this model's array. Drag a jammer to see where the nulls form and which satellites stay locked.
