Conclusions In this paper, we have presented all of the algorithmic aspects of GPSVan calibration. The positioning accuracy of the GPSVan is better than one foot in a global coordinate frame. This meets the requirements of most engineering applications. For example, we have finished projects for railroads, airports and utility applications. All projects have been completed successfully and much faster than using conventional surveying techniques. In the future, we plan to use dual frequency receivers and an inertial system to improve the accuracy to better than 10 cm. 485
