The Sun Outage Calculator (SunOut) is used to predict the duration and severity of outages due to the sun coming behind the satellite (as seen from the receive terminal). SunOut includes sophisticated models for the sun transit, the noise model of the sun, and the receive antenna characteristics, and is the most accurate tool of its kind. SunOut includes both a single and batch mode, and has configurable thresholds (noise temperature increase, G/T degradation, and C/N degradation). Results are generated in the form of customizable PDF reports.
