Title: Innovations of Russell S Figor in Vehicle Navigation Systems.
Introduction
Russell S Figor is an accomplished inventor based in Mesa, AZ (US). He has made significant contributions to the field of vehicle navigation systems, particularly in addressing the challenges associated with heading sensor bias drift.
Latest Patents
One of his notable patents is titled "Position and heading error-correction method and apparatus for vehicle navigation systems." This invention provides methods for compensating for temperature-dependent drift of bias in a vehicle heading sensor of a dead reckoning vehicle positioning system. The invention utilizes a Kalman filter to generate a calibration curve for the rate of heading sensor bias drift with temperature change. The Kalman filter calculates coefficients for a model of heading sensor bias drift rate versus temperature at each point where the vehicle is stationary. The bias drift rate calibration curve is then used to estimate a heading sensor bias periodically while the vehicle is moving. Additionally, the invention offers a method for using an aging time for temperature sensor bias drift rate to force convergence of the error variance matrix of the Kalman filter. This innovative approach enhances the accuracy of vehicle navigational systems.
