Feedback for map information is based on an integrated navigation solution for a device within a moving platform using obtained motion sensor data from a sensor assembly of the device, obtained radar measurements for the platform and obtained map information for an environment encompassing the platform. An integrated navigation solution is generated based at least in part on the obtained motion sensor data using a nonlinear state estimation technique that uses a nonlinear measurement model for radar measurements. The map information is assessed based at least in part on the integrated navigation solution and radar measurements so that feedback for the map information can be provided.

Method and system using tightly coupled radar positioning to improve map performance

An integrated navigation solution is provided for a device within a moving platform. Motion sensor data is obtained from a sensor assembly of the device, radar measurements for the platform are obtained and map information for an environment encompassing the platform is obtained. Correspondingly, an integrated navigation solution is generated based at least in part on the obtained motion sensor data using a nonlinear state estimation technique, wherein the nonlinear state estimation technique uses a nonlinear measurement model for radar measurements. Generating the integrated navigation solution includes using the sensor data with the nonlinear state estimation technique and integrating the radar measurements directly by updating the nonlinear state estimation technique using the nonlinear measurement models and the map information. The integrated navigation solution is then provided.

Method and system for positioning using tightly coupled radar, motion sensors and map information

The positioning/navigation solution of a portable device may be enhanced by obtaining motion sensor data, estimating a trajectory for the portable device from the motion sensor data, obtaining map information for an environment encompassing locations of the portable device, representing the estimated trajectory using a set of connected vectors and performing global shape matching for the set of connected vectors as an aggregate whole from start to end of the trajectory to the map information as a global optimization problem to derive a solution path.
