Introduction

Christophe Combettes is a notable inventor based in Grenoble, France. He has made significant contributions to the field of navigation technology, holding 2 patents that showcase his innovative approaches. His work focuses on methods for improving the accuracy of navigation units and vehicle positioning.

Latest Patents

One of Christophe Combettes' latest patents is a method for locating a navigation unit. This method involves establishing measurement biases for a given time, which helps reduce errors in raw measurements of pseudoranges between the navigation unit and at least three beacons. The external position of the navigation unit is estimated based on beacon positions, corrected pseudorange measurements, and a preceding estimated position. Notably, the measurement biases are established without considering the external position of the navigation unit.

Another significant patent is a method for determining the position and orientation of a vehicle. This method constructs an estimate of the instantaneous value of a physical quantity based on measurements from an inertial navigation unit. It also computes a deviation between a measurement obtained from an odometer and the estimated physical quantity, allowing for corrections to the estimated positions and orientations of the vehicle.
