This allows the user to achieve higher location accuracy, as well as stability of position tracking in urban environments. The XAHP.50 has excellent performance across the full bandwidth of the antenna and its design has an even gain across the hemisphere giving almost excellent, broad axial ratio which in turn makes it resilient to multipath rejection and excellent phase centre stability. The LNA used in the XAHP.50 ensures excellent out of band rejection and provides excellent positioning stability and reliability of GNSS signals. The robust, vandal resistant, permanent mount IP67 rated ASA enclosure is just 57mm in height and designed for ease of installation. It can be mounted on any surface; however, performance can be affected when mounted on metal surfaces. Typical Applications Include: - Autonomous Driving - Precision Positioning for Robotics - Precision Agriculture - - Inventory Management & Container tracking - Telematics & Asset Tracking - Timing Accuracy Synchronization The XAHP.50 is the latest external addition to an ongoing product road map of high precision antennas by Taoglas. For RTK applications when used on the base and/or the rover, the XAHP.50 can achieve genuine cmlevel accuracy. Cable and connectors are customizable.
