) information for the general public, from US NOAA. GPS precise orbits are derived using 24 hour data segments from the global GPS network. An informational summary file is provided to document the computation and to convey relevant information about the observed satellites, such as maneuvers or maintenance. Orbits generally are available 2 to 6 days after the observation.
