Maritime communications satellite in-orbit measurements
Abstract
As part of the Intelsat V satellite program, the first of a new series of maritime communications packages designated as the Maritime Communications Subsystem (MCS) was launched in 1982. The MCS performs the same functions as the earlier Marisat system, but it is designed to handle the growth demand for maritime communications. In-orbit tests were conducted after launch to compare spacecraft performance with prelaunch data. The maritime transponders can be tested in orbit from ground stations at Fucino, Italy, and Yamaguchi, Japan. Attention is given to the C-to L-band transponder test set, a 10.7-MHz processor used in conjunction with other components to accurately measure down-link received power, down-link receive channel tuning, measurements procedures, and computer-automated measurement methods.
