Geost Description

The program GEOST is designed as an aid for the installation of antenna systems for geo-stationary satellites. All such satellites are placed in a circular orbit above the equator. Their angular velocity is equated to the angular velocity of the earth, in order to maintain each of them always above the same point of the earth surface. Therefore, tracking a determined geo-stationary satellite is a trivial operation, as any observer sees it as a motionless object in the sky. However, the problem which arises is that of installing the antenna system in such a way that it is always directed towards points lying on the orbit of geo-stationary satellites, when it is rotated in any direction, since in this way it turns out to be easy to have access to different satellites (section 9). The program GEOST supplies the values of azimuth and elevation for three "pilot" satellites which are denoted by "Western", "Central" and "Eastern" respectively (see section 3). One should choose those which are more appropriate for the given location. The idea is to assume as "Central" the satellite which is more or less positioned on the same meridian circle as the site of the user. The "Western" and"Eastern" satellites are the extreme ones in the West and East directions respectively, among the ones seen by the observation point or, otherwise, among the ones which the user wants to receive. The program also displays the elevation under which the antenna sees the culminating point of the geo-stationary orbit: this value is generally equal to the elevation of the central satellite, if its choice has been made in a 1reasonable way. The last value provided by GEOST is the difference between the direction of the meridian of the observer and his azimuth bearing for the central satellite: this allows an easy calibration of the geographic orientation: in fact, the compass is not accurate enough for our goals. The difference is computed with respect to the South direction for the points on the boreal (northern) hemisphere and with respect to the North direction for the points on the austral (southern) hemisphere.
