Hemisphere GNSS has released its new multi-GNSS, multi-frequency four-helix HA32 UAV antenna. Hemisphere GNSS made the announcement at AUVSI Xponential, being held this week in Denver, Colorado. The HA32 is a high-performance antenna that supports GPS, GLONASS, Galileo, BeiDou, Hemisphere’s own Atlas L-band correction service. It was designed specifically for UAVs, GIS, surveying, real-time kinematic (RTK) and other applications requiring high-precision positioning and navigation. According to the company, the HA32 is built on an innovative and proprietary four-helix antenna technology that provides superior filtering and anti-jamming performance with low noise amplifier (LNA) features such as a 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 subminiature version A (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. “The features and specifications of this antenna is another example of the innovation and incredible value that Hemisphere is known for.” AUVSI Xponential attendees can visit the Hemisphere booth (#4228) to see the HA32 UAV GNSS antenna in person.
