  • Booth: 1320

Oxford Technical Solutions specialises in high-precision inertial navigation systems (IMU + GNSS) running OxTS’ own navigation engine to measure position, velocity and orientation. Typical applications commonly pair the INS with LiDAR or photogrammetry cameras for mobile mapping (land and aerial), asset management, rail survey and more.

  • Oxford Technical Solutions releases automatic boresight alignment tool.

    New GeoCloud software from inertial navigation experts OxTS [Booth 1320] not only improves the accuracy of point clouds but generates ready to use LAS point cloud files, thanks to their automatic boresight alignment tool. Using their popular xNAV550 — a real-time, PPK capable, GNSS-aided inertial navigation system— and a Velodyne LiDAR scanner, they have published results from several tests showing significant improvement in point cloud planarity after using the automatic boresight alignment tool, which should appeal to anyone conducting LiDAR surveys using land-based vehicles or UAVs.

    “As a company we already have a long and proven history with automotive manufacturers worldwide who use our inertial navigation systems to precisely measure vehicle position and attitude during development and testing,” explains Paris Austin, business manager for LiDAR survey at OxTS. “So we fully understand the importance of being able to accurately align different coordinate frames from a measurement point of view. In the LiDAR survey industry, however, it quickly became apparent to us that while the importance of borescope alignment is well known, there weren’t any cheap or easy methods customers could use to achieve perfect alignment between the different frames. So that’s why we created this tool.”

    “Gathering data for the boresight alignment tool only takes a short period of time, and only needs to be completed once as long as the inertial navigation system and LiDAR scanner remain rigidly connected. It doesn’t involve any pre-surveying either. Instead, two retro-reflective targets are placed arbitrarily on the ground and the survey vehicle is simply driven or flown in a pattern around them. The data gathered during this process can then be used by the automatic boresight tool to find the precise alignment between the LiDAR and inertial navigation frames.”

    Once the tool has been run, errors that may have been present due to misalignment when scanning the same surface from different directions are significantly reduced. This in turn improves the quality of the point cloud and reduces the amount of post-processing work that is required to align scans.

    The GeoCloud software and the automatic boresight alignment tool are compatible with all xNAV products as well as the larger Survey+ inertial navigation system — which is capable of 1 cm position accuracy and can measure roll/pitch to 0.03°. You can see both the xNAV and Survey+ and learn more about OxTS’s software solutions by going to booth 1320, where they’ll be happy to talk to you or arrange a demonstration system. Alternatively, full information can be found on their website (www.oxts.com).

  • xNAV
    Fully integrated dual antenna GNSS+inertial system that doesn’t compromise on performance. Ideal for weight and space constrained applications. Light enough to fit on many small and medium sized UAV platforms while still providing survey-grade accuracy....

  • Our xNAV systems are complete GPS-aided inertial navigation solutions designed for the size- and-weight-constrained requirements of unmanned vehicle systems. Combining state-of-the-art miniature MEMS sensors with high-performance algorithms, the xNAV systems boast one of the best price/performance ratios on the market today, delivering accurate roll/pitch, position and heading data in the most challenging of operating environments.

    Weighing just 365 g even with its rugged IP65 casing, the xNAV is light enough to fit on many small and medium sized UAV platforms while still providing survey-grade accuracy. Tight-coupling of the GNSS and INS, differential GPS, dual antennas and an onboard processor all combine to deliver high accuracy and superior performance. The xNAV achieves constant GPS heading performance of 0.15º, and drift when GPS is not available is minimized to 2.5 metres per 1 minute or 1 kilometer.

    The  xNAV can store 4GB of data for later post-processing, and features the added option of real-time processing. Post-processing and graphing is easily handled by our powerful NAVsuite software package, included free-of-charge.
