Furthermore, although some of these systems are government sponsored, most are commercial ventures, of which many are in competition with the terrestrial communications industry. Today, the applications of communication satellites reach approximately 200 countries, territories, and ocean areas for communication services of all types to both large and small terminals on land, on ships, and on aircraft. Almost every year since 1965 a new system has launched its first communication satellite. Ommunication satellites represent one of the most significant applications of space technology.
