    摘要： A track model is created for use with a GPS receiver. In one embodiment, the track model is a set of planar surfaces which approximate the contiguous surface on which navigation takes place. The GPS receiver searches for an appropriate planar surface associated with its approximate position. Having found the appropriate planar surface, the GPS receiver constrains its position using the planar surface associated with its approximate position. Using the track model improves the accuracy of the computed position at the time and improves the ambiguity estimation process so that positions with greatly improved accuracy are available sooner.

    摘要： A video broadcast of a live event is enhanced by providing graphics in the video in real time to depict the fluid flow around a moving object in the event and to provide other informative graphics regarding aerodynamic forces on the object. A detailed flow field around the object is calculated before the event, on an offline basis, for different speeds of the object and different locations of other nearby objects. The fluid flow data is represented by baseline data and modification factors or adjustments which are based on the speed of the object and the locations of the other objects. During the event, the modification factors are applied to the baseline data to determine fluid flow in real time, as the event is captured on video. In an example implementation, the objects are race cars which transmit their location and/or speed to a processing facility which provides the video.
