Reverting to default ephemeris data - AWS Ground Station

Reverting to default ephemeris data

When you upload custom ephemeris data it will override the default ephemerides AWS Ground Station uses for that particular satellite. AWS Ground Station does not use the default ephemeris again until there are no currently enabled, unexpired customer-provided ephemerides available for use. AWS Ground Station also does not list contacts past the expiration time of the current customer-provided ephemeris, even if there is a default ephemeris available past that expiration time.

To revert back to the default Space-Track ephemerides, you will need to do one of the following:

  • Delete (using DeleteEphemeris) or disable (using UpdateEphemeris) all enabled customer-provided ephemerides. You can list the customer-provided ephemerides for a satellite using ListEphemerides.

  • Wait for all existing customer-provided ephemerides to expire.

You can confirm that the default ephemeris is being used by calling GetSatellite and verifying that the source of the current ephemeris for the satellite is SPACE_TRACK. See Default ephemeris data for more information on default ephemerides.
