Description

The AJU-8160D Dual Eight-Element Anti-Jamming GNSS Antenna is a navigation anti-jamming antenna that integrates a multi-element controlled reception pattern antenna (CRPA) array, an anti-jamming processing module and a built-in GNSS receiver in a single unit. It supports reception, amplification, down-conversion, filtering, anti-jamming processing and up-converted RF output of 8-channel BDS B1 / GPS L1 / Galileo E1 + L5 signals. Using adaptive spatial-domain filtering, it suppresses 1–7 jammers from different directions, including wideband, narrowband, frequency-sweep and pulse jamming, and combinations thereof, over a spatial coverage of Azimuth 0°–360°, elevation -10°–90°. The built-in receiver performs PVT (position, velocity, time) solving and outputs positioning results (Horizontal ≤ 7 m, vertical ≤ 9 m (95%, PDOP ≤ 4); velocity ≤ 0.2 m/s (95%)) through the data interface, while a processed RF output (-55 dBm to -70 dBm, 50 Ω, VSWR ≤ 2.0) is available for external GNSS receivers. The antenna port withstands RF input of ≥ 10 W. The unit is rated for operation from -40 °C to +70 °C (10%–90% RH, non-condensing) with storage from -45 °C to +85 °C (10%–95% RH, non-condensing) and an ingress protection of ≥ IP65, and is qualified with shock (Tested per ISO 19453-3:2018) and vibration (Tested per ISO 5309:2023) testing per civil UAV environmental test standards. Installation notes require the metallic base to be mounted against a good heat-dissipating surface and the antenna face to have an unobstructed view of the sky; when installed inside a platform, the radome-side surface must be RF-transparent (≥92% transmission in the L band).
