Septentrio, a leader in high-precision GNSS/INS positioning, and XenomatiX, provider of true-solid-state-LiDAR technology for autonomous applications and road management, are starting a partnership enabling high-quality LiDAR systems.
XenomatiX will be using the compact and robust GNSS/INS receiver from Septentrio, AsteRx SBi3 Pro+, to provide millimeter accurate analysis of pavement conditions using global positioning coordinates.
The high-quality GNSS/INS receiver will be a part of Xenomatix’ Road LiDAR called XenoTrack, which has been the product of choice for road surveyors and road management companies. The AsteRx SBi3, high-performance RTK GNSS/INS receiver with a dual antenna setup, ensures cm-accurate geotagging of the XenoTrack point cloud frames for relative and global millimeter accuracy over large distances. Moreover, the unique inertial GNSS – IMU integration algorithm enables dead-reckoning, which means continuous positioning in environments of low satellite visibility where GNSS outages occur.
While traditional road scanning based on laser profilers rely solely on extremely accurate GNSS/INS to stitch consecutive profiles together, the XenoTrack captures a 3D topography of an entire area in a single shot. XenomatiX’ sensor fusion algorithms combine visual SLAM techniques with GNSS, IMU and CAN to obtain a seamless map of the road shape.
The Septentrio proprietary GNSS+ technology plays a key role in delivering the accuracy and reliability needed for XenoTrack. The AIM+ Advanced Interference Mitigation technology ensures robust positioning even in the presence of jammers, which may be found aboard vehicles trying to avoid road tolling. When the sky is obstructed for an extended period, the built-in RAIM+ integrity algorithm serves as an indicator of when it is best to give priority to other sensor input to maintain a high-quality system.
XenomatiX offers a complete mapping system as well as services including data from the XenoTrack sensor, camera and RTK GNSS/INS receiver with dual antenna — all delivered in an easy-to-install solution on a standard vehicle.
