TDK Corp. announced the launch of InvenSense Coursa Drive software, an inertial-aided positioning solution for autonomous vehicle (AV) platform developers. A high-performance extension of the InvenSense Positioning Library (IPL), Coursa Drive is designed to enhance inertial-only vehicle positioning to <0.2% of distance traveled.
Coursa Drive’s inertial navigation system (INS) calibrates using absolute position inputs from either high-accuracy GNSS receivers or from perception-based systems (camera, radar, LiDAR) with HD maps. In real time, Coursa Drive reportedly provides high-rate, 100 Hz delta positions and orientation to the AV system, complementing the lower-rate position references from GNSS and perception systems. For improved system fault-tolerance, Coursa Drive can provide decimeter position precision for short periods when the GNSS or perception systems are uncertain or unavailable.
