JSAT (satellite Constellation)
The JSAT constellation is a Communication satellite, communication and Satellite broadcasting, broadcasting satellite constellation formerly operated by JSAT Corporation and currently by SKY Perfect JSAT, SKY Perfect JSAT Group. It has become the most important commercial constellation in Japan, and fifth in the world. It has practically amalgamated all private satellite operators in Japan, with only Broadcasting Satellite System Corporation, B-SAT left as a local competitor. JSAT began in 1985, with the opening by the Government of Japan, of the communication markets in Japan and the founding of JSAT Corporation, Japan Communications Satellite Company, JSAT Corporation, Satellite Japan Corporation, SKY Perfect JSAT, Space Communications Corporation. It grew by own investment, mergers and acquisitions of the parent companies. As of August 2016, it includes the fleets of three previously mentioned companies, Horizons Satellite and NTT DoCoMo and the DSN (satellite network), DSN mili ...

SSL 1300
The SSL 1300, previously the LS-1300 and the FS-1300, is a satellite bus produced by Maxar Technologies. Total broadcast power ranges from 5 to 25 kW, and the platform can accommodate from 12 to 150 transponders. The SSL 1300 is a modular platform and Maxar Technologies no longer reports designators for sub-versions, such as: 1300E, 1300HL, 1300S, 1300X. First available in the late 1980s, the SSL 1300 platform underwent revision multiple times over its design life, all the while remaining a popular communications platform. The earliest models provided 5,000 RF watts of transmitter power, weighed 5,500 kg, and required a 4-meter diameter launch fairing. Newer models provide double that, approximately 10,000 RF watts of transmitter power, weigh 6,700 kg, and require a 5-meter diameter launch fairing. SSL stated that they would use electric propulsion for North-South station keeping for the first time on the MBSat in 2004. The subsystem was supplied by International S ...

Cape Canaveral Air Force Station Space Launch Complex 40
Space Launch Complex 40 (SLC-40), sometimes referred to as "Slick Forty," is one of two launch pad, launch pads located at the Integrate-Transfer-Launch Complex in Cape Canaveral Space Force Station, Florida. It initially opened as Launch Complex 40 (LC-40) and was used by the United States Air Force alongside the neighboring Cape Canaveral Space Launch Complex 41, Space Launch Complex 41 for the Titan (rocket family), Titan III program. It initially saw use by the Titan IIIC throughout the 1960s and 1970s, before getting retrofitted for the Titan 34D during the 1980s. In the 1990s, Martin Marietta and the Air Force upgraded it to launch the Commercial Titan III, but the rocket's lack of success caused the pad to be used by the Titan IV throughout the decade and into the 2000s. Following the Titan family's retirement, the SLC-40 lease was given to SpaceX in 2007 for use by their new rocket, the Falcon 9. Since the early 2010s, the pad has transformed into a high-volume launch site ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a Transponder (satellite communications), transponder; it creates a communication channel between a source transmitter and a Radio receiver, receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The radio waves used for telecommunications links travel by Line-of-sight propagation, line of sight and so are obstructe ...

Tracking, Telemetry, And Control
A spacecraft is a vehicle that is designed to fly and operate in outer space. Spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific research are space probe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Design Review (U
A design review is a milestone within a product development process whereby a design is evaluated against its requirements in order to verify the outcomes of previous activities and identify issues before committing to—and, if need be, to re-prioritise—further work. The ultimate design review, if successful, therefore triggers the product launch or product release. The conduct of design reviews is compulsory as part of design controls, when developing products in certain regulated contexts such as medical devices. By definition, a review must include persons who are external to the design team. Contents of a design review In order to evaluate a design against its requirements, a number of means may be considered, such as: *Physical tests. *Engineering simulations. *Examinations (Walk-through). Timing of design reviews Most formalised systems engineering processes recognise that the cost of correcting a fault increases as it progresses through the development process. Ad ...

Superbird-B2
Superbird-B2, also known by its pre-launch designation Superbird-4, is a Japanese communications satellite which is operated by SKY Perfect JSAT Group. It was originally built and launched for the Space Communications Corporation (SCC), which merged with JSAT Corporation (JSAT) in October 2008. It was constructed by Hughes Space and Communications and is based on the HS-601 HP satellite bus. Satellite Space Communications Corporation (SCC) of Tokyo, Japan, ordered its second spacecraft from Hughes Space and Communications (HSC), on 6 April 1998. It was built at the Los Angeles plant, California, United States. Launch Launch occurred on 18 February 2000, at 01:04 UTC. The launch was contracted by Arianespace, and used an Ariane 44LP H10-3 launch vehicle flying from ELA-2 at the Centre Spatial Guyanais. Following its launch and on-orbit testing, it was placed in geostationary orbit at 162° East, from where it provides communications services to Japan. It is equipped with ...

Geosynchronous Transfer Orbit
In space mission design, a geostationary transfer orbit (GTO) or geosynchronous transfer orbit is a highly elliptical type of geocentric orbit, usually with a perigee as low as low Earth orbit (LEO) and an apogee as high as geostationary orbit (GEO). Satellites that are destined for geosynchronous orbit (GSO) or GEO are often put into a GTO as an intermediate step for reaching their final orbit. Larson, Wiley J. and James R. Wertz, eds. Space Mission Design and Analysis, 2nd Edition. Published jointly by Microcosm, Inc. (Torrance, CA) and Kluwer Academic Publishers (Dordrecht/Boston/London). 1991. Manufacturers of launch vehicles often advertise the amount of payload the vehicle can put into GTO. Background Geostationary and geosynchronous orbits are very desirable for many communication and Earth observation satellites. However, the delta-v, and therefore financial, cost to send a spacecraft to such orbits is very high due to their high orbital radius. A GTO is an intermediary ...
