Abstract
A reference station system comprises a plurality of GPS reference stations that are distributed in different parts of the world to be able to simultaneously gather a complete set of satellite vehicle ephemeredes. Each reference station is associated with a network server connected to the Internet. Each network server posts ephemeredes, NAV-data, and other useful information for clients derived from its corresponding reference station. All such network servers inject their information in all the other servers in the system Each server validates and authenticates any injected data. Each client is also qualified as a subscriber before being able to access the complete ephemeredes database and other GPS system information.
