A vehicle position determination system and method provide accurate vehicle positioning using a global positioning system. Spatial bias techniques are used to improve positioning accuracy while the vehicle is in the midst of a relatively linear path and is not approaching a drastically nonlinear path. The use of spatial bias techniques is suspended while the vehicle is approaching or in a drastically nonlinear path.

A method for implementing spatial bias techniques in a system that determines the position of a vehicle, comprising the steps of: (1) receiving navigation signals from a terrestrial positioning system; (2) computing position estimates of the vehicle using spatial bias techniques and said navigation

A method for implementing spatial bias techniques in a system that determines the position of a vehicle, comprising the steps of: (1) receiving navigation signals from a terrestrial positioning system; (2) computing position estimates of the vehicle using spatial bias techniques and said navigation signals; (3) if the vehicle approaches a drastic nonlinear path, then ceasing use of said spatial bias techniques; and (4) computing said position estimates without said spatial bias techniques until the vehicle approaches a relatively linear path.
