Sun Outage Calculation

Sun Outage

The actual occurrence of sun outage time and duration depends on many parameters like signal level, data format, antenna size, pointing accuracy and the mathematical model used in the program. The prediction result provided by this program serves only as a rough sun outage estimation, which may vary from the actual occurrence by 5 to 10 minutes, and should not be treated as a highly accurate engineering or operational tool.

The estimation is generally appropriate for earth stations located within AsiaSat's footprints. For sites beyond AsiaSat's coverage, the generated result may be invalid.
