Abstract
The Jet Propulsion Laboratory's (JPL's) automated GPS data analysis service, which is available via the Internet, has been tested. This service is attractive not only because data submission and retrieval are entirely automated on the Internet, but also because it makes centimeter positioning possible for individual dual-frequency receivers. To learn more about this service, the repeatability of position solutions were investigated by means of two simple experiments. The positions of a continuously operating reference station have been computed repeatedly for observation times ranging from 1 hour to 24 hours. In addition, short baseline repeatability and accuracy were tested. Centimeter-level results were obtained. The difference in the vertical definition of the electronic center for antennas of different types could readily be identified. The JPL service is easy to use, even in its present form (which one might label version 1.0). © 1999 John Wiley & Sons, Inc.
