Import Precise Ephemeris Files (.sp3)

Import a precise ephemeris file to bring in parameters used by a global navigation satellite receiver to predict the location of a satellite and its clock behavior. Each satellite contains and transmits ephemeris data about its orbit and clock every 30 seconds.

Precise Ephemeris Files (.sp3) are files that contain highly accurate satellite orbit information. These files are used in various applications, including GPS and GNSS (Global Navigation Satellite System) data processing, to provide precise satellite positions. The data in .sp3 files is typically generated by organizations such as the International GNSS Service (IGS) and includes detailed information about the satellite's position and velocity at specific times. This information is crucial for applications requiring high precision, such as geodesy, surveying, and navigation.

Note: You can also download .sp3 data from NGS CORS stations.
