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 current constellation operates in an equatorial orbit some 8,000 kilometers in altitude an unusual orbit that trains O3bs Ka-band spot beams on territories around the equator to provide broadband connectivity.
The updated SKYLON D1 configuration has a payload of 15 tonnes to a 300km equatorial orbit.
Arianespace lofted four more satellites in the O3b constellation (the "Other 3 billion") into an equatorial orbit.
From Arctic--and Antarctic--latitudes, connecting with satellites in geostationary equatorial orbit is a challenge because they are very close to the horizon.
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.
VesselSat1 was launched into an equatorial orbit in October 2011 and is now providing full commercial service.
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.
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.
