Scientific paper

The problem of a possible satellite collision due to the geostationary orbit decay is examined in view of the increasing number of geostationary satellites and the hazard of in-orbit exhaustion of fuel. A number of orbital decay mechanisms are outlined, among them electromagnetic drag on a charged satellite, meteorite and micrometeorite collisions, and solar radiation pressure. It is suggested that a geostationary satellite be boosted up to an altitude of 100-150 km prior to the expected exhaustion of fuel, which will delay the problem by about 500 years. Calculations show that for a satellite of a type of INSAT-1A the amount of fuel required for such a boost is approximately 1 kg.
