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 ...

JCSAT-16
JCSAT-16 is a geostationary communications satellite operated by SKY Perfect JSAT Group and designed and manufactured by SSL on the SSL 1300 platform. It has a launch weight of , a power production capacity of 8.5 kW and a 15-year design life. Its payload is composed of Ku band and Ka band transponders. SKY Perfect JSAT Group plans to use JCSAT-16 as an in-orbit backup satellite for the Ku- and Ka-band satellites serving the Japanese market. SpaceX's Falcon 9 Flight 28 propelled JCSAT-16 to a geosynchronous transfer orbit on August 14, 2016. History In April 2014, SSL announced that it had been awarded a contract by SKY Perfect JSAT Group to manufacture two satellites: JCSAT-15 and JCSAT-16. The latter would be an 8.5 kW satellite with Ku band and Ka band payload for a broad range of orbital locations. It would be used as a back-up to the existing fleet.

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] |

It had a launch mass of and a 15-year design life. Like most satellites based on the A2100 platform, it uses a LEROS-1C LAE for orbit raising. Its payload comprises thirty-two 27 MHz and twelve 36 MHz Ku band transponders for a total bandwidth of 1.296 GHz. The satellite is used primarily for multi-channel pay per view business. Besides the main beam, two steerable beams enable it to reconfigure its orbit services. It's mainly used for broadcasting digital television channels.

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 ...

Autonomous Spaceport Drone Ship
An autonomous spaceport drone ship (ASDS) is a modified ocean-going barge developed by SpaceX and equipped with propulsion systems to maintain precise position and a large floating landing platform, landing platform. They were developed to recover the First stage (rocketry), first stage (also called the booster) of its SpaceX launch vehicles, launch vehicles. By recovering and reusing these boosters, SpaceX has significantly reduced the cost of space launch. SpaceX operates three ASDS: ''Just Read the Instructions (II)'' (JRTI), ''A Shortfall of Gravitas'' (ASOG), and ''Of Course I Still Love You'' (OCISLY). JRTI and ASOG operate from Port Canaveral supporting launches from John F. Kennedy Space Center, Kennedy Space Center and Cape Canaveral Space Force Station landing in the Atlantic Ocean, while OCISLY operates from the Port of Long Beach supporting launches from Vandenberg Space Force Base landing in the Pacific Ocean. Depending on mission requirements, SpaceX can Return ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geostationary 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 intermedia ...
