OxTS is pleased to announce that our indoor positioning solution Pozyx 2GAD, has been recognized as Software Innovation of the Year by the Automotive Testing Technology International Awards 2022 panel.
Despite highly fierce competition, the panel felt that OxTS’s solution deserved to take the accolade. It is the fruit of a unique project with Horiba MIRA. Needing accurate indoor position data for its purpose-built multilevel parking test facility, Assured CAV Parking, Horiba MIRA reached out to OxTS, which worked with its channel partner, Datron Technology, and technology partner, Pozyx, to forge the cutting-edge solution.
For the Assured CAV application, the initial requirement was for the tech to operate on one of the parking facility’s five levels. Floor-to-floor and outdoor-to-indoor transitions would be supported at a later date, giving full floor, ramp and transitional coverage. Most position measurement devices used for automotive testing rely on GNSS signals in position calculations, owing to their ubiquity and centimeter-level accuracy. However, GNSS-aided solutions were not suitable for Horiba MIRA’s facility, as the signals would be obstructed by the physical infrastructure. Given that the solution would be used for the sole purpose of developing, validating and verifying AVP, park assist and other related systems, there was a particular focus on low-speed maneuvers with small vehicle-to-target distances.
Badged the Pozyx 2GAD (to Generic Aiding Data), it enhances data accuracy in GNSS-denied spaces, offering indoor positioning accuracy to within 5cm. The Pozyx 2GAD uses ultra-wideband (UWB) as an aiding source for the OxTS RT3000 v3. This enables real-time position updates, provided by the Pozyx UWB system, which is fused with OxTS INS inertial measurements for improved navigation performance. UWB was the ideal candidate due to its accuracy comparable with camera and lidar at a cost similar to wi-fi and Bluetooth Low Energy. Furthermore, by employing the Pozyx UWB system, no obvious changes to the infrastructure of the test area were needed.
Horiba MIRA continues to work with OxTS, Pozyx and Datron Technology to include floor-to-floor and indoor-to-outdoor transitions, which will enable it to offer an augmented automated valet parking analysis facility.
