xNAV650
Precise localisation in the smallest, lightest OxTS package
Overview
xNAV650
The xNAV650 is OxTS' smallest, lightest, and most affordable Inertial Navigation System, combining over 20 years of navigation experience with cutting-edge MEMS IMU sensors and survey-grade GNSS receivers.
At just 77 × 63 × 24 mm and 130 g, the xNAV650 is ideal for UAV integration, lightweight mapping payloads, and space-constrained mobile mapping platforms. It delivers 2 cm RTK position accuracy with 0.1° heading and 0.05° pitch/roll.
The gx/ix tightly-coupled GNSS engine maintains reliable performance in challenging environments, while Ethernet and serial interfaces with optional PTP timestamping simplify integration with LiDAR scanners and mapping equipment. Free NAVsuite software is included.
