Oxford Technical Solutions has launched the xNAV650 inertial navigation system (INS), the corporate’s smallest and lightest INS up to now. It measures 77 x 63 x 24 mm and weighs 130 g and is designed to assist surveyors to reap the benefits of extremely correct inertial measurements when low payload measurement and weight are key necessities.

The xNAV650 INS is appropriate for a variety of purposes the place utilizing a UAV is the popular information assortment methodology.  These embrace bridge, constructing, forestry and rail surveys, coastal monitoring, pipeline exploration, map creation and extra.

In one instance, Dronezone used the xNAV650 INS and a Velodyne VLP-16 LiDAR on a drone to conduct a scan of an growing older bridge to search for structural and potential hazards from overgrown foliage. By fusing the timing, place and inertial information from the INS with the uncooked information of the Velodyne VLP-16 (utilizing OxTS’ LiDAR georeferencing software program OxTS Georeferencer), the surveyor was in a position to produce a extremely correct 3D pointcloud of the bridge. The resultant pointcloud enabled engineers to simply and precisely pinpoint areas of the bridge that want nearer consideration.

The OxTS Georeferencer allows georeferencing pointclouds from Velodyne, Hesai and Ouster LiDAR sensors. The firm is working to combine new LiDAR sensors from a wider vary of producers into OxTS Georeferencer.

OxTS NAVsuite software program is included with all OxTS INS. This full vary of software program instruments permits customers of OxTS’ units to configure and post-process information with ease.  Other non-compulsory software program options are additionally obtainable together with Precision Time Protocol (PTP) and gx/ix tight-coupling expertise.

  • PTP permits for a a lot less complicated LiDAR survey set-up over ethernet while concurrently stamping out time-drift by utilising the high-quality INS clock supply – GNSS.
  • GX/IX tight-coupling expertise, OxTS’ personal proprietary navigation engine, ensures that customers of OxTS Inertial Navigation Systems obtain probably the most correct measurements attainable even in powerful GNSS circumstances.
