Sun Interference

Sun Interference Data for satellites owned and/or operated by Intelsat

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 information on sun interference affects satellite transmissions and how outages are predicted, please check out What are Sun Outages?

Sun Interference Calculator

If you are an Intelsat customer, you can also use our Sun Interference Calculator on MyIntelsat to determine when Intelsat satellites will be affected and your signal may be potentially degraded.

Our Sun Outage Calculator generates estimates based on geometric angles only and does not account for parameters such as RF link margin, antenna mispointing, actual antenna performance (main lobe and side lobe) or exact frequency used, all of which will affect the actual observed RF outage duration.

To be conservative, we recommend allowing a margin by subtracting 10 minutes from the predicted start time and adding 10 minutes to the predicted end time generated by the calculator. Additionally, it is possible for some users to observe no discernable degradation during the predicted sun outage period, depending on each user's situation (e.g. link margin, antenna mispointing, antenna performance and frequency used).

Note: Seasonal references refer to their timing in the Northern Hemisphere.
