GEOPoint is an easy to use satellite antenna pointing calculator, for geostationary communications satellites. It calculates the azimuth and elevation pointing angles from a given location on the earth towards a specified geostationary satellite. The program also calculates polarisation tilt angles, estimates dates and times of annual sun-outage events, calculates antenna G/T, eirp and frequency stability, and estimates path-loss and rain-attenuation based on ITU-R climate models. As used by Hausfeld Consulting for satellite communications planning.
