Abstract

The invention described herein relates to aiding a Satellite Positioning System (SPS) receiver of a platform with a data interface to the platform data. The platform, for example, could be a vehicle, ship, aircraft, or a pedestrian. The SPS receiver would be used to track the location of the platform. The data interface would facilitate access by the SPS receiver to the data of the platform, and the SPS receiver in turn could provide SPS data (such as position, speed, and heading) to the platform. A further aspect of the invention includes hardware or software used by the data interface and the SPS receiver to provide, format, time-stamp, synchronize, and match platform data or SPS receiver data.

Claims

1-6. -6. (canceled)

7. A method for synchronizing platform data with SPS data for aiding in platform location, comprising:

receiving SPS data in a SPS receiver;

tracking the time at which the SPS data is received;

receiving platform data in the SPS receiver;

tracking the time at which the platform data is received in the SPS receiver;

and matching the SPS data with the platform data based on time.

8. The method of claim 7, further comprising:

performing location calculations with the matched SPS and platform data.
