Hemisphere UAV GNSS AntennaHemisphere GNSS has announced the launch of its new multi-GNSS, multi-frequency 4-helix HA32 UAV (unmanned aerial vehicle) antenna. The HA32 is a high-performance antenna that supports GPS, GLONASS, Galileo, BeiDou and Hemisphere’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 4-helix antenna technology that provides high filtering and anti-jamming performance with LNA features such as low noise figure of 2.0 dB (typical) and up to 30 dB gain (typical). Suitable for most outdoor and harsh operating environments, the HA32 antenna is sealed in a durable and ruggedized IP67-rated enclosure for protection against dust and water and is equipped with an O-ring. The lightweight (40 g typical) and compact form-factor (40 mm x 75 mm) design of the antenna makes it resistant to wind when installed on UAVs and offers easy integration with a single SMA RF connector.

“We are very excited to be introducing this extremely competitive entry-level UAV GNSS antenna for a wide range of positioning and navigation applications such as UAVs, GIS, and RTK,” said Miles Ware, Director of Marketing with Hemisphere GNSS.

Hemisphere’s Atlas is a flexible, scalable GNSS-based global L-band correction service providing robust performance and correction data for GPS, GLONASS, and BeiDou. Atlas delivers correction signals via L-band satellites to provide accuracies ranging from sub-meter to sub-decimeter levels, and leverages approximately 200 reference stations worldwide, providing coverage to virtually the entire globe.

Atlas is available on all Hemisphere Atlas-capable single and multi-frequency, multi-GNSS hardware, and complements third-party GNSS receivers by using Atlas corrections with Hemisphere’s BaseLink and SmartLink capabilities. Using multi-frequency hardware, Atlas creates faster convergence times, and is robust and reliable in canopy or foliage covered areas. Atlas Basic provides users of both single and multi-frequency Atlas-capable hardware the ability to achieve better than SBAS performance anywhere in the world where the Atlas correction service is available. Atlas Basic offers a proven accuracy of 30 cm (pass-to-pass 95%) to 50 cm (absolute 95%) and instantaneous sub-meter accuracy.
