Sun Outage Prediction tool
Uses Google maps for location.
Possible to generate reports for several sites and/or satellites

Supports two prediction modes:
-Outage based on C/N degradation
-Outage based the Sun passing inside the RX antenna 3dB beamwidth

Sun Outage Visualizer Simulator Tool for Geostationary Orbit Satellites
Projects the affected area on Google Maps
-Plot for single satellite
-Plot for selected satellites
-Plot for all satellites
-Draw 1dB C/N reduction contour
-Automatic 1s,5s,10s or 60s updates
-C/N reduction calculations partly based on ITU-R S.1525-1 & ITU-R BO.1506 simplified model

Supports different prediction modes:
-Outage based on C/N degradation
-Outage based on C/N degradation exceeding link margin
-Outage based on the Sun passing inside the RX antenna 3dB beamwidth
-Generate Sun outage Prediction reports for several sites and/or satellites

Footprint Simulator Tool for Geostationary Orbit Satellites (Version 2)
Generate a footprint based on theoretical parabolic transmitter antenna. Supports multispot beam and elliptical beam(elliptical TX antenna) with user defined TX antenna rotation. Beam is projected on earth/Google maps. The tool is not generating real footprints but is well suited for educational use. In some cases (for a non-shaped beam) , the generated footprints can be close to the real thing if TX antenna size, frequency & beamcenter is known.
