Abstract: The method of the selection of launch conditions for a satellite at substantially synchronous altitude above the earth in a slightly inclined orbit relative to the equatorial plane of the earth to limit the inclination that may be induced by perturbations for significantly long periods of time without the need of orbit adjusting means (north-south station keeping means) aboard the satellite. One or more such satellites are arranged in a communication system in cooperation with at least one ground station. In a two-satellite system a communication channel is continuously operated between at least one satellite and the ground station notwithstanding solar outages.
