Clarke belt, which is a geostationary orbit, often referred to as a geosynchronous equatorial orbit, is a circular geosynchronous orbit 35,786 km above Earth's equator all the telecommunications and television satellites are put on.
A geostationary equatorial orbit (GEO) is a circular geosynchronous orbit in the plane of the Earth's equator with a radius of approximately 42,164 km (measured from the center of the Earth).
The design target for the SKYLON 01 vehicle was 12 tonnes to a 300km equatorial orbit, 10.5 tonnes to a 460km equatorial spacestation or 9.5 tonnes to a 460km x 28.5 deg spacestation when operating from an equatorial site.
Arianespace lofted four more satellites in the O3b constellation (the "Other 3 billion") into an equatorial orbit. Built by Thales Alenia Space as prime contractor, these four satellites will enable O3b Networks to supply broadband Internet access at moderate prices to emerging markets in Asia, Africa, Latin America, Australia and the Middle East, totaling nearly 150 countries surrounding the equator where broadband access is rarely available.
"The 1,425-kilogram (3,135-pound) satellite will be put into equatorial orbit 20 minutes after lift-off," Karnik told AFP in Bangalore, where the state-run space agency is based.
NASA is scheduled to launch the four-ton observatory in 2007 into a low-altitude equatorial orbit.
Owing to the rotation of the source of the field, Kepler's 3rd Law for the polar orbit is not the same as that for the equatorial orbit, so that stable photon orbits are also different in the polar and equatorial orbits, showing that in the rotating configurations spacetime is no longer isotropic.
This allows it to potentially "see" much more per hour than a satellite in equatorial orbit. As a result, it takes less fuel to launch from Kodiak compared to Cape Canaveral or Vandenburg Air Force Base, the two competing launch facilities in the U.S.
Ellipso, which plans to commence limited service in the year 2001, will have 16 satellites (plus 1 spare) in a unique orbital configuration: Two highly elliptical orbits (4,700-mile apogee, 400-mile perigee) with 5 satellites in each, and one circular, equatorial orbit (5,000-mile altitude) with 6 satellites (plus 1 spare).
The first phase, known as ECCO, will incorporate 12 satellites in equatorial orbit. The constellation will comprise an additional 42 satellites - six located in each of seven planes.
VesselSat1 was launched into an equatorial orbit in October 2011 and is now providing full commercial service.
