Position of a Geostationary Satellite
1987The aim of this exercise is to determine the position of a geostationary satellite on the sky for any observer on the Earth’s surface.

The Geostationary Applications Satellite
1988Berlin offers an in-depth look into all the engineering aspects of geostationary satellite design, construction, and launch. Geostationary satellites have opened new doors for the peaceful use of outer space. From vantage points 22,000 miles above the equator, they permit people anywhere on land, at sea, or in the air to communicate with each other ...

Interferometric imaging of geostationary satellites
SPIE Proceedings, 2012Even the longest geosatellite, at 40 m, subtends only 0.2 arcsec (1 microradian). Determining structure and orientation with 10 cm resolution requires a 90 m telescope at visual wavelengths, or an interferometer. We de- scribe the application of optical interferometry to observations of complex extended targets such as geosatellites, and discuss ...

Orbits of Geostationary TV Satellites
International Astronomical Union Colloquium, 1997AbstractIn the frame of European cooperation among some stations (Brussels, Praha, Cagliari, Torino, Penc, Borowiec, Teddington, Metsahovi, Besançon and San Fernando) the method of time comparisons by a TV link has been used for orbit determination of the Eutelsat-F2 satellite.

Geostationary-satellite earth coverage
Proceedings of the Institution of Electrical Engineers, 1975The basic problem considered is the relation of the shape of the beam of a geostationary satellite antenna to the area that it covers on the surface of the earth. It is envisaged that circular or elliptical beams may be used, but the beam is defined in general terms by a beam contour on a beam plane perpendicular to the beam axis by two angular co ...

Satellites in Non-Geostationary Orbits
1993This Chapter examines recent trends towards the use of communications satellites in low earth orbits and in other non-geostationary orbits. It is shown why the use of such orbits could offer the possibility of satellite communications from miniature hand-held earth terminals. The various classes of non-geostationary orbits are first described.
