Cape Canaveral Space Launch Complex 40
Space Launch Complex 40 (SLC-40), previously Launch Complex 40 (LC-40) is a launch pad for rockets located at the north end of Cape Canaveral Space Force Station, Florida. The launch pad was used by the United States Air Force for 55 Titan III and Titan IV launches between 1965 and 2005. The facility underwent multiple upgrades including the design and construction of towers with retractable and foldable platforms for vehicle assembly, instrumentation and monitoring. After 2007, the US Air Force leased the complex to SpaceX to launch the Falcon 9 rocket. As of August 2022, there have been 93 launches of the Falcon 9 from the complex. The site was heavily damaged following the September 2016 Falcon 9 flight 29 incident, due to a catastrophic failure during a static fire test. The complex was repaired and returned to operational status in December 2017 for the CRS-13 mission. Launch history Rocket launches Titan The first launch from SLC-40 (initially named LC-40) ...

Palapa-D
Palapa-D was an Indonesian geostationary communications satellite which was operated by Indosat Ooredoo. It was built by Thales Alenia Space, based on the Spacebus-4000B3 satellite bus, and carries 35 C-band and 5 Ku-band transponders. It was positioned in geostationary orbit at a longitude of 113° East, where it will replace the Palapa-C2 satellite. Indosat ordered Palapa-D from Thales Alenia Space on 2 July 2007. The satellite was built without using American components, and was therefore not restricted by U.S. International Traffic in Arms Regulations (ITAR), which allowed the China Great Wall Industry Corporation to be selected as a launch service provider. Launch A Long March 3B launch vehicle, flying from Launch Area-2 at the Xichang Satellite Launch Centre was used to launch Palapa-D. A problem with the third stage of its carrier rocket left it in an incorrect orbit, which was subsequently corrected using the spacecraft's onboard propulsion system. After launch, Pa ...

Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a 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 high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications sate ...

Autonomous Spaceport Drone Ship
An autonomous spaceport drone ship (ASDS) is an ocean-going vessel derived from a deck barge, outfitted with station-keeping engines and a large landing platform and is autonomously controlled when on station for a landing. Construction of such ships was commissioned by aerospace company SpaceX to allow recovery of launch vehicle first stages at sea for missions that do not carry enough fuel to return to the launch site after boosting spacecraft onto an orbital or interplanetary trajectory. SpaceX has three operational drone ships: ''Just Read the Instructions (II)'' (JRTI) and ''A Shortfall of Gravitas'' (ASOG), operating in the Atlantic for launches from Kennedy Space Center and Cape Canaveral Space Force Station, and ''Of Course I Still Love You'' (OCISLY), operating in the Pacific for supporting missions from Vandenberg Space Force Base. JRTI operated in the Pacific Ocean for Vandenberg Air Force Base launches from 2016 to 2019 before leaving the Port of Los Angeles ...

Internet Protocol Suite
The Internet protocol suite, commonly known as TCP/IP, is a framework for organizing the set of communication protocols used in the Internet and similar computer networks according to functional criteria. The foundational protocols in the suite are the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), and the Internet Protocol (IP). In the development of this networking model, early versions of it were known as the Department of Defense (DoD) model because the research and development were funded by the United States Department of Defense through DARPA. The Internet protocol suite provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed, and received. This functionality is organized into four abstraction layers, which classify all related protocols according to each protocol's scope of networking. An implementation of the layers for a particular application forms a protocol stack. From lowest to high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-definition Television
High-definition television (HD or HDTV) describes a television system which provides a substantially higher image resolution than the previous generation of technologies. The term has been used since 1936; in more recent times, it refers to the generation following standard-definition television (SDTV), often abbreviated to HDTV or HD-TV. It is the current de facto standard video format used in most broadcasts: terrestrial broadcast television, cable television, satellite television and Blu-ray Discs. Formats HDTV may be transmitted in various formats: * 720p (1280 horizontal pixels × 720 lines): 921,600 pixels * 1080i (1920×1080) interlaced scan: 1,036,800 pixels (~1.04 MP). * 1080p (1920×1080) progressive scan: 2,073,600 pixels (~2.07 MP). ** Some countries also use a non-standard CEA resolution, such as 1440×1080i: 777,600 pixels (~0.78 MP) per field or 1,555,200 pixels (~1.56 MP) per frame When transmitted at two megapixels per frame, HDTV provides about five times ...

Launch Service Provider
A launch service provider (LSP) is a type of company which specialises in launching spacecraft. In 2018, the launch services sector accounted for $5.5 billion out of a total $344.5 billion "global space economy". It is responsible for the ordering, conversion or construction of the carrier rocket, assembly and stacking, payload integration, and ultimately conducting the launch itself. Some of these tasks may be delegated or sub-contracted to other companies. For example, United Launch Alliance has formally subcontracted the production of GEM solid rocket motors for their Delta II and Delta IV (Medium version) rockets to Alliant Techsystems, both vehicles are now retired. An LSP does not necessarily build all the rockets it launches. A document central to successful launch service provision is the Interface Control Document (ICD), a contract that specifies the integration and mission requirements responsibilities across the service provider and the service solicitor. In some cases ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transponder (satellite Communications)
A communications satellite's transponder is the series of interconnected units that form a communications channel between the receiving and the transmitting antennas. It is mainly used in satellite communication to transfer the received signals. A transponder is typically composed of: * an input band-limiting device (an input band-pass filter), * an input low-noise amplifier (LNA), designed to amplify the signals received from the Earth station (normally very weak, because of the large distances involved), * a frequency translator (normally composed of an oscillator and a frequency mixer) used to convert the frequency of the received signal to the frequency required for the transmitted signal, * an output band-pass filter, * a power amplifier (this can be a traveling-wave tube or a solid-state amplifier). Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Most transponders operate on a ...
