Rugged UAV GNSS antenna

May 28th, 2018, Published in Articles: PositionIT

Hemisphere GNSS announced the new multi-GNSS, multi-frequency four-helix HA32 UAV antenna. The high-performance antenna supports GPS, Glonass, Galileo, BeiDou, and the company’s own Atlas L-band correction service, and was designed specifically for UAVs, GIS, surveying, RTK, and other applications requiring high-precision positioning and navigation. The HA32 is built on a proprietary four-helix antenna technology that provides filtering and anti-jamming performance with LNA features such as low noise figure (typically 2,0 dB) and up to 30 dB gain (typical). Suitable for most outdoor and harsh operating environments, the antenna is sealed in a durable and ruggedised IP67-rated enclosure for protection against dust and water and is equipped with an O-ring. Its lightweight (40 g) and compact form-factor (40 mm x 75 mm) design makes the antenna resistant to wind when installed on UAVs and offers easy integration with a single SMA RF connector. Atlas is a flexible and scalable GNSS-based global L-band correction service providing robust performance and correction data for GPS, Glonass, and BeiDou. The service delivers correction signals via L-band satellites to provide accuracies ranging from sub-meter to sub-decimetre levels.
