Abstract
A navigation-satellite receiver network comprises a server connected to the Internet to provide real-time correction information to clients. The server includes a GPS receiver that provides for tracking of a constellation of navigation satellites. When a client is online, it can receive satellite position and velocity information in the form of a polynomial and coefficients. Clock, ionosphere, troposphere, and other corrections are all bundled into one polynomial. The client therefore never computes or uses almanac or ephemeris.
