702SP
Boeing 702 is a communication satellite bus family designed and manufactured by the Boeing Satellite Development Center, and flown from the late-1990s into the 2020s. It covers satellites massing from to with power outputs from 3 to 18 kW and can carry up to approximately 100 high-power transponders. The baseline Boeing 702 is compatible with several orbital launch systems, including Atlas V, Ariane 5, Delta IV, Falcon 9, Proton, and the Sea Launch-operated Zenit 3SL. Platform versions After the introduction of the original 702 in 1997, the platform has been continually updated. New members of the platform have been introduced through the years, which allowed the common systems and approaches to span the whole range of mass and power for geosynchronous orbit satellites. The family currently spans four different members: the 702HP for high-power applications, the 702HP-GEO for mobile-telephone services, the 702MP for medium-power requirements and the 702SP for small sate ...

Satmex
Satmex (Satélites Mexicanos) was a company set up in Mexico in the mid-1990s through 2014 that operated space communication satellites that provide services to the Americas. In 2014, it was acquired by Eutelsat, and Eutelsat now operates the three satellites formerly operated by Satmex. History SATMEX existed as a company from approximately 1997 until 2014, when it was Mergers and acquisitions, acquired by Eutelsat.

Sea Launch
Sea Launch was a multinational—Norway, Russia, Ukraine, United States—spacecraft launch company founded in 1995 that provided orbital launch services from 1999–2014. The company used a mobile maritime launch platform for equatorial launches of commercial payloads on specialized Zenit-3SL rockets from a former mobile/floating oil drilling rig renamed ''Odyssey''. By 2014, it had assembled and launched thirty-two rockets, with an additional three failures and one partial failure. All commercial payloads were communications satellites intended for geostationary transfer orbit with such customers as EchoStar, DirecTV, XM Satellite Radio, PanAmSat, and Thuraya. The approach Sea Launch LLC used was to assemble the launcher on a purpose-built ship ''Sea Launch Commander'' in Nimitz Rd., Long Beach, California, USA. The assembled spacecraft was then positioned on top of the self-propelled ''Odyssey'' floating launch platform and moved to the equatorial Pacific Ocean for launc ...

Thuraya
Thuraya ( ar, الثريا, Gulf Arabic pron.: ; from the Arabic name for the constellation of the Pleiades, ''Thurayya'') is a United Arab Emirates-based regional mobile-satellite service (MSS) provider. The company operates two geosynchronous satellites and provides telecommunications coverage in more than 161 countries in Europe, the Middle East, North, Central and East Africa, Asia and Australia. Thuraya's L-band network delivers voice and data services. Thuraya is the mobile satellite services subsidiary of Yahsat, a global satellite operator based in the United Arab Emirates, fully owned by Mubadala Investment Company. The geostationary nature of the service implies high round trip times from satellite to earth leading to a noticeable lag being present during voice calls. Services * Voice communications with satellite phones or fixed terminals * Short message service * 60 kbit/s downlink and 15 kbit/s uplink "GMPRS" mobile data service on Thuraya satellite phones * 444 kbi ...

Falcon 9 Flight 22
SES-9 is a geostationary communications satellite operated by SES S.A. It was launched from Cape Canaveral SLC-40 by a Falcon 9 Full Thrust launch vehicle on 4 March 2016. Satellite description SES-9 is a large communications satellite operating in geostationary orbit at the 108.2° East, providing communications services to Northeast Asia, South Asia and Indonesia, maritime communications for vessels in the Indian Ocean, and mobility beams for "seamless in-flight connectivity" for domestic Asian airlines of Indonesia and the Philippines. The satellite was built by Boeing, using a model BSS-702HP satellite bus. SES-9 had a mass of at launch, the largest Falcon 9 payload yet to a highly- energetic geosynchronous transfer orbit (GTO). SES S.A. used the spacecraft's own propulsion capabilities to circularize the trajectory to a geostationary orbit. Market and coverage SES-9 has 57 high-power Ku-band transponders, equivalent to 81 transponders of 36 MHz bandwidth and, co-loc ...

Reaction Control System
A reaction control system (RCS) is a spacecraft system that uses thrusters to provide attitude control and translation. Alternatively, reaction wheels are used for attitude control. Use of diverted engine thrust to provide stable attitude control of a short-or-vertical takeoff and landing aircraft below conventional winged flight speeds, such as with the Harrier "jump jet", may also be referred to as a reaction control system. Reaction control systems are capable of providing small amounts of thrust in any desired direction or combination of directions. An RCS is also capable of providing torque to allow control of rotation (roll, pitch, and yaw). Reaction control systems often use combinations of large and small ( vernier) thrusters, to allow different levels of response. Uses Spacecraft reaction control systems are used for: * attitude control during different stages of a mission; * station keeping in orbit; * close maneuvering during docking procedures; * control o ...

Bipropellant Rocket
A liquid-propellant rocket or liquid rocket utilizes a rocket engine that uses liquid propellants. Liquids are desirable because they have a reasonably high density and high specific impulse (''I''sp). This allows the volume of the propellant tanks to be relatively low. It is also possible to use lightweight centrifugal turbopumps to pump the rocket propellant from the tanks into the combustion chamber, which means that the propellants can be kept under low pressure. This permits the use of low-mass propellant tanks that do not need to resist the high pressures needed to store significant amounts of gasses, resulting in a low mass ratio for the rocket. An inert gas stored in a tank at a high pressure is sometimes used instead of pumps in simpler small engines to force the propellants into the combustion chamber. These engines may have a higher mass ratio, but are usually more reliable, and are therefore used widely in satellites for orbit maintenance. Liquid rockets can be mono ...
