Claim Text:
1. A method for improving GPS calculations in a GPS enabled device, comprising the steps of: a. introducing a shim to circumvent an existing programming interface between a pseudo-range equation processing module and a location services module in a GPS enabled device; b. obtaining a NIST certified time value and comparing that value to existing time values to be used by said pseudo-range equation processing module in making pseudo-range calculations; c. utilizing said NIST certified time value in pseudo-range equation processing when said NIST certified time value is more accurate than the existing time value being utilized thereby improving pseudo-range calculation results; d. transferring said improved pseudo-range calculation results to a location services module in said device; and, e. utilizing said shim to spoof a GPS enabled device operating system into utilizing said improved pseudo-range calculation results as if they were produced with original time values.
