Title :
Communication satellites: orbital information efficiency

Abstract :
The dependence of the relative daily average amount of information transmitted on the altitude and inclination of the spacecraft´s circular orbit are obtained. The notions of the integral density of the information flow available at the earth station visibility zone and the integral density of the daily global information flow are introduced as the orbital efficiency indices. The specific expense per information unit depending on the orbit altitude is also estimated
