Satellite Bus
A satellite bus (or spacecraft bus) is the main body and structural component of a satellite or spacecraft, in which the payload and all scientific instruments are held. Bus-derived satellites are less customized than specially-produced satellites, but have specific equipment added to meet customer requirements, for example with specialized sensors or transponders, in order to achieve a specific mission. They are commonly used for geosynchronous satellites, particularly communications satellites, but are most commonly used in spacecraft which occupy low Earth orbit missions. Examples Some satellite bus examples include: * Boeing DS&S 702 * Lockheed Martin Space Systems A2100 * Moog Inc. SL-OMV, Meteor, Meteorite * * INVAP ARSAT-3K * Airbus D&S Eurostar * ISRO's I-1K, I-2K, I-3K, I-4K, I-6K, and Indian Mini Satellite bus * NASA Ames MCSB * SSL 1300 * family * Orbital ATK Star Bus family, inc GEOStar * Mitsubishi Electric DS2000 * Spacecraft bus of the Jam ...

Communications Satellite Bus
Communication is commonly defined as the transmission of information. Its precise definition is disputed and there are disagreements about whether unintentional or failed transmissions are included and whether communication not only transmits meaning but also creates it. Models of communication are simplified overviews of its main components and their interactions. Many models include the idea that a source uses a coding system to express information in the form of a message. The message is sent through a channel to a receiver who has to decode it to understand it. The main field of inquiry investigating communication is called communication studies. A common way to classify communication is by whether information is exchanged between humans, members of other species, or non-living entities such as computers. For human communication, a central contrast is between verbal and non-verbal communication. Verbal communication involves the exchange of messages in linguistic form ...

ARSAT-3K
ARSAT-3K is a geostationary communications satellite bus designed and manufactured by INVAP of Argentina for the local telecommunication company ARSAT S.A. It is a small (4.2 kW of power generation and of launch mass) three axis stabilized platform designed, manufactured and tested completely in Argentina. It is capable of carrying up to of payload with a maximum power consumption of 3.4 kW at the end of life. It currently uses only chemical propulsion, but a hybrid solution which would use bi-propellant propulsion for orbit raising and electric propulsion for station keeping is being developed. A purely electric propulsion version is planned. Platform Versions ARSAT-3K The ARSAT-3K is the initial version of this bus. It is comparable to the Thales Alenia Space Spacebus 3000B2. It uses an integrated chemical propulsion system supplied by EADS Astrium for both orbit raising and station keeping. ARSAT-3H The ARSAT-3H is the second version of this bus, which initia ...

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 ...

SSL (company)
SSL, formerly Space Systems/Loral, LLC (SS/L), of Palo Alto, California, is a wholly owned manufacturing subsidiary of Maxar Technologies. SSL designs and builds satellites and space systems for a wide variety of government and commercial customers. Its products include high-powered direct-to-home broadcast satellites, commercial weather satellites, digital audio radio satellites, Earth observation satellites and spot-beam satellites for data networking applications. History The company was founded as the Western Development Laboratories (WDL) of Philco in 1957, which became Philco-Ford in 1966. The Space Systems Division was made a stand-alone Division of Aeronutronic/ Ford Aerospace and was acquired by Loral Corp. in 1990 for $715 million from Ford Motor Company, and renamed Space Systems/Loral. All other divisions of Ford Aerospace including Western Development Labs located in San Jose were also acquired by Loral at that time. In 2012 Space Systems/Loral was acquired by ...

Modular Common Spacecraft Bus
The Modular Common Spacecraft Bus (MCSB) is a fast-development, low-cost, general purpose spacecraft platform. Its modular design is intended to reduce the cost, complexity, and lead time on missions by providing a reliable, well-characterized system that can carry a variety of payloads. According to NASA, "the spacecraft is roughly one tenth the price of a conventional uncrewed mission and could be used to land on the Moon, orbit Earth, or rendezvous with near-Earth objects." History The MCSB supervisor, Alan Weston, obtained from NASA Ames Research Center $4 million in internal funding to get the project started. Using that money, the prototype was built in about 15 months during 2007–2008. The fast concept development time is due in part to the preliminary use of repurposed SCUBA air tanks and an engine that uses cold gas, in place of a conventional rocket engine. This allowed the team to perform indoor flight tests as fast as every 40 minutes in their laboratory, rather ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ames Research Center
The Ames Research Center (ARC), also known as NASA Ames, is a major NASA research center at Moffett Federal Airfield in California's Silicon Valley. It was founded in 1939 as the second National Advisory Committee for Aeronautics (NACA) laboratory. That agency was dissolved and its assets and personnel transferred to the newly created NASA, National Aeronautics and Space Administration (NASA) on October 1, 1958. NASA Ames is named in honor of Joseph Sweetman Ames, a physicist and one of the founding members of NACA. At last estimate NASA Ames had over US$3 billion in capital equipment, 2,300 research personnel and a US$750 million annual budget. Ames was founded to conduct wind-tunnel research on the aerodynamics of propeller-driven aircraft; however, its role has expanded to encompass spaceflight and information technology. Ames plays a role in many NASA missions. It provides leadership in astrobiology; small satellites; robotic lunar exploration; the search for habitable plane ...
