Product Description

Product Overview

AJU‑8160D is a dual eight‑element GNSS anti‑jamming antenna unit developed for civilian and commercial navigation platforms that require stable satellite positioning in complex signal environments. It is compatible with a wide range of platforms, including industrial UAVs, agricultural drones, autonomous systems, mobile mapping equipment, marine navigation platforms and robotics systems, where reliable GNSS reception is important for safe and continuous operation.

Unlike a conventional GNSS antenna, AJU‑8160D is designed to strengthen useful satellite signals while suppressing unwanted interference across supported bands, helping receivers maintain navigation performance when signal conditions become challenging. This integrated navigation anti‑jamming unit supports BDS B1, GPS L1+L2 or L1+L5, and Galileo E1 signal paths, making it suitable for commercial and civilian applications such as inspection drones, precision agriculture, autonomous equipment, hydrographic survey systems and smart robotics.

Civilian applications

Our GNSS anti-jamming antennas are intended for lawful civilian and commercial use, especially where electromagnetic noise, dense infrastructure or accidental interference can reduce navigation quality. Typical applications include industrial UAV operations, agricultural drones, unmanned ground vehicles, mobile mapping, marine navigation, robotics and other autonomous systems that rely on accurate positioning, velocity and timing data.

The AJU‑8160D architecture uses multiple antenna elements and adaptive interference suppression to improve signal continuity, which is why comparable CRPA-based anti-jamming designs are widely discussed for high-reliability civilian navigation and infrastructure protection scenarios. The result is stronger positioning stability, fewer signal dropouts and better operational safety for professional platforms working in busy, noisy or interference-prone environments.

Installation and contact

For best performance, the metal base should be mounted with effective heat dissipation, and the antenna top should face open sky or sit beneath an L‑band RF‑transparent cover with at least 92% transmission. This helps the AJU‑8160D deliver stable GNSS performance for civilian drones, autonomous machines, marine systems and mapping platforms operating in difficult environments.
