| - Syncom (for "synchronous communication satellite") started as a 1961 NASA program for active geosynchronous communication satellites, all of which were developed and manufactured by Hughes Space and Communications. Syncom 2, launched in 1963, was the world's first geosynchronous communications satellite. Syncom 3, launched in 1964, was the world's first geostationary satellite. In the 1980s, the series was continued as Syncom IV with some much larger satellites, also manufactured by Hughes. They were leased to the United States military under the Leasat program.
- Syncom, the first commercial experimental satellite to be placed in a geosynchronous orbit, was to become the most important of the experimental satellites to the U.S. Navy and DoD, as well as to the general public. The concept for Syncom had been proposed by the Hughes Aircraft Company, turned down by DoD, and then awarded a contract by NASA in 1961.

| - Syncom, the first commercial experimental satellite to be placed in a geosynchronous orbit, was to become the most important of the experimental satellites to the U.S. Navy and DoD, as well as to the general public. The concept for Syncom had been proposed by the Hughes Aircraft Company, turned down by DoD, and then awarded a contract by NASA in 1961. Syncom-I, launched in February 1963, did not achieve orbit. Syncom-II (launched in July 1963) and Syncom-III (in August 1964) succeeded and demonstrated the great utility of geosynchronous orbit, which has been used for almost all subsequent U.S. communications satellites.
