	Syncom - Wikipedia, the free encyclopedia
		Syncom was a program of active geosynchronous communication satellites which was started by NASA in 1961.
		The Syncom IV series were considerably larger and heavier than the earlier satellites and were leased to the United States military under the LEASAT programme.
		Syncom 1 was to be the first geosynchronous communications satellite.

	NASA Experimental Communications Satellites
		The Syncom 2 orbit was inclined 33 degrees to the equator so that it appeared to move 33 degrees North and 33 degrees South in a figure 8 path over a 24 hour period as observed from the ground.
		Syncom 1 was launched on February 14, 1963 into a nearly synchronous orbit, but failed during the apogee motor burn.
		Syncom 2 was launched on July 26, 1963 after improvements in the nitrogen tank design were incorporated and it was a success.

	Syncom
		The first geostationary satellite was Syncom 3, launched to provide live daily TV coverage of the 1964 Tokyo Olympics which it did successfully.
		The two functioning Syncoms were eventually handed over to the Department of Defense to provide reliable transpacific communications; Syncom 2 was “walked” along the equator using its control thrusters, until it had joined its sister on the other side of the globe.
		Syncom was the descendant of Relay and Telstar and the immediate of more capable geostationary satellites such as Intelsat.

	Syncom Week - Story 2
		Syncom 2 was developed and built by Hughes Aircraft Company (whose satellite manufacturing unit later became Boeing Satellite Systems) to demonstrate the feasibility of communications from geosynchronous orbit, which offers numerous advantages over low-Earth orbit.
		On August 19, 1964, Syncom 2 was joined in orbit by Syncom 3, the third of three geosynchronous satellites built by Hughes under a contract with NASA.
		Syncom 3 was deployed in time to provide the first live television coverage of an Olympics, relaying the 1964 Games in Tokyo.

	Syncom 1, 2, 3
		Syncom 1 was designed to be the first test of a communication satellite in geosynchronous orbit.
		Syncom 3 was launched from Cape Kennedy on 16 August 1964 and injected into an elliptical orbit inclined 16 degrees to the equator following a third stage yaw maneuver.
		These maneuvers were completed by 23 September, and Syncom 3 was used in a variety of communications tests, including the transmission of the Olympics, transmissions between the Philippines, USNS Kingsport, and Camp Roberts, California, and teletype transmissions to an aircraft on the San Francisco-Honolulu route.

		A series of events was supposed to occur, culminating in the firing of a booster rocket on board the satellite, which would carry it to the much higher orbit where communications satellites normally operate.
		With his feet firmly anchored in a foot restraint on the end of the Candarm, he was carefully maneuvered by Lounge to within reach of the satellite.
		Fisher then opened two panels on Syncom and operated on its innards, hot-wiring it to new command and power devices on the outside that would allow the satellite to be controlled from earth.

		This meant that Syncom 2 was not actually stationary over one point on the Earth's surface, but moved in an elongated figure-eight pattern between 33° north and 33° south of the equator.
		Syncom 2 measured 2 feet, 4 inches (0.71 meter) in diameter, with a solar panel height of 1 foot, 3 inches (0.39 cm).
		Syncom 3 was changed to one 5-MHz and one switchable (50 kHz or 13 MHz) double-conversion repeater.

		Syncom 1, a model of the satellite only intended for a few voice channels never made it off the ground, exploding at launch in February 1963.
		With a wider band receiver, Syncom 3 could accommodate television signals and was used during the Tokyo Olympics to deliver the first continuous transoceanic television broadcast.
		With the success of Syncom 2 and Syncom 3, Hughes Aircraft was selected to build a satellite based on its previously demonstrated technology but with commercial frequencies.

		The first geostationary satellite was Syncom 3, launched in August 1964 into a 1113 x 38084 km x 16.80 deg, 694.5 min transfer orbit.
		The perigee of Syncom 3's transfer orbit was unusually high; between 1970 and 1990, almost all geostationary satellites used transfer orbits with perigees between 150 and 600 km, and apogees from 34000 to 41000 km.
		This type of orbit was used by Syncom 3 and Early Bird and then abandoned in favour of lower perigees.

		Syncom, a joint NASA and the Department of Defense satellite built by Hughes, was designed for Clarke's geosynchronous orbit.
		Syncom 3 was launched the following year in August 1964 into a geostationary orbit, in time for relaying the 1964 Tokyo Olympics.
		Syncom used military frequencies, and so trials by telecommunications companies tended be done with Relay and Telstar, which used commercial bands.

		The U.S. Department of Defense launched Syncom 3 in 1964.
		Syncom 3 was the first communication satellite to use a geostationary orbit—that is, an orbit that keeps the satellite over the same spot above Earth’s equator.
		GOES is augmented by Meteosat 3, a European weather satellite also in geostationary orbit.

		This hook was used to attempt to activate a stuck switch on the side of the Syncom.
		However, the maneuver did not activate the Syncom, and it was left in a useless orbit for possible future repair.
		During the first of two space walks, Fisher floated to the Syncom with an MMU backpack and brought the satellite back to the shuttle, where van Hoften assisted in securing the satellite in the shuttle's payloab bay.

		Syncom 3 was different from its predecessor in other ways, notably in its orbital pattern.
		Syncom 3 had a geostationary orbit, while the orbit of Syncom 2 was inclined thirty-three degrees to the equator, so that over a twenty-four-hour period, it appeared to move thirty-three degrees north and thirty-three degrees south in a "figure 8" pattern as observed from the ground.
		Launched on 12 July 1989 on an Ariane 3 rocket, Olympus was a large multipurpose satellite demonstrating and promoting new applications in television broadcasting, intercity telephone routing, and the use of the Ka-band for videoconferencing and low-rate data transfer for business communication.

		Unfortunately, Syncom 1—launched 1963 February 14—while successfully reaching geosynchronous orbit in an inclined, eccentric orbit was unsuccessful due to an electronics failure.
		Syncom 2—launched 1963 July 26—became the first operational geosynchronous communications satellite.
		Syncom 3—launched 1964 August 19—became the first geostationary satellite, finally fulfilling the prediction made by Clarke almost twenty years earlier.

		The first synchronous orbit satellite, Syncom, led to the development of the Early Bird Intelsat I commercial communications spacecraft as well as the ATS series of NASA research satellites.
		Syncom 1 suffered a propulsion failure and never reached proper orbit.
		Syncom 3 was even more successful, and the U.S. Department of Defense also used it for experiments.

		In addition, new booster motors provide 25% more thrust, and 3 of the 9 motors are equipped with thrust vector control for improved manoeuvrability.
		For example, Tiros 3 was the first weather satellite to discover a hurricane, spotting Esther two days before conventional means would have revealed it.
		The Delta II has had only one total failure (and one partial failure, Koreasat-1) since its first launch in February 1989 — an incredible 99% success rate — and is currently in its longest streak ever of consecutive successes, with Delta 313 being the 65th success in a row.

		The Syncom satellite had a short cylindrical body that was spun about its axis to provide stabilization in orbit.
		Like Syncom 1, it was not intended to achieve a stationary synchronous orbit because of the extra propellant weight and control complexity required to attain 0-deg inclination.
		The Advanced Syncom program was sometimes called Syncom II, which, in some references, is difficult to distinguish from the second satellite of the original Syncom program (Syncom 2 in this report).

		The first two Syncom satellites launched achieved an orbit that was geosynchronous but not geostationary; in other words, their rotational period matched the Earth’s own, but their orbits were inclined and eccentric.
		Syncom 3, launched in August 1964, circled the equator without inclination, successfully becoming the first geostationary satellite.
		Of subsequent NASA projects, the most significant was the Advanced Communications Technology Satellite (ACTS), launched from the space shuttle Discovery in September 1993.
