Provide custom ephemeris data

Access to the Ephemeris API is provided only on an as-needed basis. If you require the ability to upload custom ephemeris data, you should contact <aws-groundstation@amazon.com>.

Overview

The Ephemeris API allows custom ephemerides to be uploaded to AWS Ground Station for use with a satellite. These ephemerides override the default ephemerides from Space-Track (see: Default ephemeris data). We support receiving ephemeris data in Orbit Ephemeris Message (OEM), two-line element (TLE), and azimuth elevation formats.

AWS Ground Station treats ephemerides as Individualized Usage Data. If you use this optional feature, AWS will use your ephemeris data to provide troubleshooting support.

Uploading custom ephemerides can improve the quality of tracking, handle operations where no Space-Track ephemerides are available to AWS Ground Station, and account for maneuvers.

To troubleshoot an invalid ephemeris see: Troubleshoot invalid ephemerides

Example: Using customer-provided ephemerides with AWS Ground Station

For more detailed instructions for using customer-provided ephemerides with AWS Ground Station, see Using customer-provided ephemerides with AWS Ground Station and it's associated GitHub repository aws-samples/aws-groundstation-cpe.
