Abstract: A television station which receives remotely originated signals via relay satellite can time its local sync and burst signal generators with a standard reference frequency which it itself sends to the relay satellite and receives back from the relay satellite. This permits locally originated signals timed by the local sync and burst signal generators to be synchronized with the remotely originated signals to good approximation, despite time delay variations of the remotely originated signals caused by variations of the relay satellite orbit, permitting an adjustable delay line to then be used to compensate remnant delay variations. Consequently, cross fading or other special-effects mixing between locally and remotely originated programs is facilitated.

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.
