Title: **Innovator Douglas W. Friedrich: Advancing Vehicle Navigation Technologies**
Introduction
Douglas W. Friedrich, an inventive mind based in Pekin, IL, holds an impressive portfolio with seven patents to his name. With a focus on enhancing vehicle positioning technologies, Friedrich's contributions are making significant strides in the field of autonomous navigation.
Latest Patents
Among Friedrich's notable innovations is a system and method for using parabolic models to improve the position of autonomous vehicles. This innovative system accurately determines the vehicle's terrestrial position in real time. The process begins with the derivation of a first position estimate from global positioning system satellites or pseudolites when satellites are unavailable. A second estimate arises from an inertial reference unit or vehicle odometer, which is then combined and filtered using novel techniques to produce a more reliable third position estimate. This system ensures that vehicles can navigate autonomously with heightened precision.
Another significant patent involves a vehicle position determination system that utilizes global positioning technology to provide accurate vehicle positioning. It employs spatial bias techniques to enhance positioning accuracy when a vehicle travels along a relatively linear path but suspends these techniques when approaching sharply nonlinear paths. Friedrich’s innovations are paving the way for safer and more efficient autonomous vehicles.
