Cape Canaveral Space Launch Complex 40
Space Launch Complex 40 (SLC-40), sometimes referred to as "Slick Forty," is one of two 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 Space Launch Complex 41 for the 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 for the Falcon 9, being mainly used to service the company's Starlink ...

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 ...

Indian Regional Navigational Satellite System
Indian Regional Navigation Satellite System (IRNSS), with an operational name of NavIC (acronym for Navigation with Indian Constellation; also, 'sailor' or 'navigator' in Indian languages), is an autonomous regional satellite navigation system that provides accurate real-time positioning and timing services. It covers India and a region extending around it, with plans for further extension up to . An extended service area lies between the primary service area and a rectangle area enclosed by the 30th parallel south to the 50th parallel north and the 30th meridian east to the 130th meridian east, beyond borders where some of the NavIC satellites are visible but the position is not always computable with assured accuracy. The system currently consists of a constellation of eight satellites, with two additional satellites on ground as stand-by. The constellation is in orbit as of 2018. NavIC will provide two levels of service, the "standard positioning service", which will be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Next Generation Launch Vehicle
The Next Generation Launch Vehicle (NGLV) is a family of three-stage Reusable launch vehicle#Partially reusable launch systems, partially reusable Medium-lift launch vehicle, medium to super heavy-lift launch vehicle, currently under development by the ISRO, Indian Space Research Organisation (ISRO). The family of these vehicles are designed to replace currently operational systems like the Polar Satellite Launch Vehicle, PSLV and Geosynchronous Satellite Launch Vehicle, GSLV. Previously referred to as Unified Launch Vehicle (ULV), the project is now being called as project Soorya. This family of three launchers were previously being designed for replacing the different core propulsion modules of PSLV, GSLV, and LVM3 respectively with a common semi-cryogenic engine and hence it was named as ULV. Unlike the latest proposal of the launcher, the initial proposals were planned to be Expendable launch system, expendable. But the new proposals under the name of NGLV suggests launcher ...

Geostationary Orbit
A geostationary orbit, also referred to as a geosynchronous equatorial orbit''Geostationary orbit'' and ''Geosynchronous (equatorial) orbit'' are used somewhat interchangeably in sources. (GEO), is a circular orbit, circular geosynchronous orbit in altitude above Earth's equator, in radius from Earth's center, and following the retrograde and prograde motion, direction of Earth's rotation. An object in such an orbit has an orbital period equal to Earth's rotational period, one sidereal time, sidereal day, and so to ground observers it appears motionless, in a fixed position in the sky. The concept of a geostationary orbit was popularised by the science fiction writer Arthur C. Clarke in the 1940s as a way to revolutionise telecommunications, and the first satellite to be placed in this kind of orbit was launched in 1963. Communications satellites are often placed in a geostationary orbit so that Earth-based satellite dish, satellite antennas do not have to rotate to track t ...
