US Patent 7460950 System for establishing a vehicle parameter

A system for establishing a vehicle parameter including collecting signals from a satellite and deriving a reference vehicle parameter from the satellite signals. Signals from a vehicle sensor are also collected and an estimated vehicle parameter is derived therefrom. Once the satellite signals and the estimated vehicle parameter signals are collected, parameters for a correction algorithm are generated and thereafter, the correction algorithm is applied to vehicle sensor signals to generate a corrected vehicle parameter or to generate a vehicle tire status parameter.
