Adjusting processor clock information using a clock drift estimate

Software embodied on a storage medium comprising a plurality of program instructions operable to cause a processor to:

• estimate an amount of drift in a processor clock signal based on global positioning satellite information, the processor clock signal used to clock the processor;
• generate adjusted processor clock information using the amount of drift in the processor clock signal;
• and
• generate a navigation solution using the adjusted processor clock information.

A method comprising:

• estimating an amount of drift in a processor clock signal based on global positioning satellite information, the processor clock signal used to clock a processor;
• adjusting the processor clock signal for the amount of drift in order to generate adjusted processor clock information;
• and
• generating a navigation solution using the adjusted processor clock information for controlling a vehicle.

An apparatus comprising:

• means for estimating an amount of drift in a processor clock signal based on global positioning satellite information, the processor clock signal used to clock a processor;
• means for adjusting the processor clock signal for the amount of drift in order to generate adjusted processor clock information;
• and
• means for generating a navigation solution using the adjusted processor clock information.
