Keplerian Data

We update the data for each satellite on a weekly basis, usually on Thursday and Friday. The start dates are Saturday and Sunday, respectively, and are valid for a period of seven days from epoch.

We provide additional data when station-keeping or relocation maneuvers are scheduled – typically one to three messages per month. Maneuver files may be issued any day of the week, and become effective at the time of the maneuver. They remain effective until superseded by another maneuver update file or by the next set of routine weekly data.

Sun Interference Calculator

During certain times of the year, energy from the Sun can overpower a satellite’s signal. This is called a Sun fade, Sun transit or Sun outage. For further details, please refer to the Sun Interference Background document.

Launch the Sun Interference Calculator. If you have any issues please contact Support.

Satellite Configuration & Technical Information

Intelsat satellites are designed with configurable beacons, beam pointing, transponders connectivity, and transponders gain.

Payload configuration notes (PRM) that provide satellite configuration information for each satellite in service are available on MyIntelsat.
