Unmanned Surface Vehicle Antenna System
Product Overview
The Unmanned Surface Vehicle Antenna System collects local position information such as longitude, latitude, and altitude via Beidou/GPS, and combines it with the location data of shore-based antennas. Through automatic or manual alignment and attitude stabilization, the system enables wireless link communication. When the antenna system loses its target and enters blind-search mode, it can perform horizontal omnidirectional blind search or horizontal ±30° blind search, responding to start and stop commands from the host computer until communication is restored. The system uses differential GPS to measure the antenna’s north orientation, providing feedback on both position and antenna pointing information. This system is widely used on unmanned platforms such as USVs, unmanned boats, and unmanned ground vehicles, achieving highly adaptive communication performance.
