Sun Outage Calculator

If the satellite you are looking for is not in the "satellite" list, enter its location in the "Longitude (0° to +360°)" field.

If the location of your dish is not in the "location" list, enter its location in the "N Lat (+90° to -90°)" and "W Lon (0° to +360°)" fields.

NOTE:
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).
