A geostationary (GEO) satellite is a satellite positioned over a fixed point at the equator and rotating synchronously with the Earth. It appears stationary for an observer on the ground. a) What is its orbital period (be precise with respect to the mean solar day and the sidereal day)? b) Calculate the radius and altitude of the orbit. c) What is the orbit semimajor axis, inclination, and eccentricity? d) Calculate the (plane) angle subtended by the earth as seen from the GEO orbit e) Calculate the maximum geographical latitude that a GEO satellite can see. (This effect puts polar regions off limits for GEO satellite applications.) f) Calculate the elevation angle at which the spacecraft is seen from Los Angeles, Ca., (geographical latitude 34.0); assume that the spacecraft is positioned over longitude of Los Angeles. g) Calculate the minimal round-trip time delay for a radio communications link between Los Angeles and the satellite.
