Ephemerides Service

Ephemerides can be provided using a query service. The function of a query service is to provide a single source for a specific information type, and to return it without affecting other continuous streams.

The ephemerides service provides a complete GPS ephemeris each time an application connects to the selected port. Upon connection the receiver returns the orbit parameters in RT17 format for each SV. Once all the ephemeris parameters have been received, the application then should close the port. The ephemeris for each satellite is provided only once each time the port is opened, it is not a continuous stream.
