Product Round-Up: Rugged GNSS Antennas for Unmanned & Autonomous Applications

GNSS Antennas are incorporated into a wide range of unmanned and autonomous vehicles, including Unmanned Aerial Vehicles (UAV, drones, UAS), Unmanned Ground Vehicles (UGV, ground robotics), and Uncrewed Surface Vessels (USV, unmanned boats), to support high-accuracy positioning and precision navigation.

This product round-up highlights a number of rugged GNSS Antennas that are suitable for use in the harsh and extreme conditions often associated with aerospace, maritime, and ground-based unmanned and autonomous vehicles, as well as munitions and robotics.

Environmental sealing and rugged IP-rated enclosures provide protection from extremes of temperature as well as moisture, while low SWaP (Size, Weight and Power) form factors meet the demand for lightweight sub-systems.
