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 s 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. an easy to use dialog-style user interface for data entry and calculation;

entry of earth station location coordinates directly, or by clicking on a world map;

select earth station location from a built-in list of world major cities;

display of satellite azimuth and elevation contours on the world map to aid in site selection;

entry of latitude and loude coordinates in d,m,s format, or as decimal degrees;

entry of coordinates in Australian AMG coordinates and automatic conversion to latitude, loude;

calculation of pointing angles to a specified satellite for common types of antenna mount;

display of azimuth pointing angles relative to True North, and relative to local magnetic north;

estimation of antenna movement limits for inclined orbit satellites;

calculation of polarisation tilt angle, loop-back path delay, and required antenna tracking speeds;

estimation of the peak dates and s for sun-interference on the receive link.
