Specifically, geosynchronous Earth orbit (GEO) may be a synonym for geosynchronous equatorial orbit, [2] or geostationary Earth orbit. [3] To avoid confusion, geosynchronous satellites that are not in geostationary orbit are sometimes referred to as being in an inclined geostationary orbit (IGSO) .
Anik F2 has lost two of its four thrusters. As a result, continued operation uses significantly more fuel. Telesat has announced [23] that it is acquiring an in-orbit satellite to replace Anik F2. An FCC filing by Telesat has since revealed [24] that the company is buying AMC-11 from SES. Once the FCC has issued its permit, Telesat can take ...
Following on where the F.3 left off, the F.5 was a version of the F.2/4 with an open rotor (unducted) thrust augmenter added to the end of the jet pipe, somewhat remote from the HP turbine The 5 ft 6 in diameter fixed pitch propellers, which contra-rotated, were driven by a four-stage statorless LP turbine unit, similar to that of the F.3 ...

ViaSat-3 is a planned global constellation of three geostationary K a-band communications satellites, the first of which was launched in 2023. [1] Operated by Viasat, Inc., the satellites are intended to provide broadband connectivity with speeds of 100-plus megabits per second to homes, business and enterprise internet users, commercial, government and business aircraft, as well as government ...
GTO is a highly elliptical Earth orbit with an apogee (the point in the orbit of the moon or a satellite at which it is furthest from the earth) of 42,164 km (26,199 mi), [3] or a height of 35,786 km (22,236 mi) above sea level, which corresponds to the geostationary altitude.
SBIRS GEO-3 in orbit. SBIRS-GEO 3 was manufactured by Lockheed Martin Space and was built upon the A2100M, a militarized, radiation hardened satellite bus that provides power, attitude control, command and control, and a communications subsystem with five separate mission data downlinks to meet mission requirements, including system survivability and endurability requirements.
[8] [9] Specifically, geosynchronous Earth orbit (GEO) may be a synonym for geosynchronous equatorial orbit, [10] or geostationary Earth orbit. [ 11 ] The first geosynchronous satellite was designed by Harold Rosen while he was working at Hughes Aircraft in 1959.
