List Of GPS Satellites
, 83 Global Positioning System navigation satellites have been built: 31 are launched and operational, one has launched and is undergoing the commissioning process, seven are in reserve or testing, 39 are retired, and two were lost during launch. A single non-operational prototype was never launched. Two Block III satellites have completed construction and have been declared "Available For Launch" (AFL). The next scheduled launch is GPS III SV09, currently targeted for late 2025. The constellation requires a minimum of 24 operational satellites, and allows for up to 32; typically, 31 are operational at any one time. A GPS receiver needs four satellites to work out its position in three dimensions. SVNs are "space vehicle numbers" which are serial numbers assigned to each GPS satellite. PRNs are the "pseudo-random noise" sequences, or Gold code A Gold code, also known as Gold sequence, is a type of binary sequence, used in telecommunications (CDMA) and satellite navigatio ...

Animation Of GPS Satellite Orbits
Animation is a filmmaking technique whereby image, still images are manipulated to create Motion picture, moving images. In traditional animation, images are drawn or painted by hand on cel, transparent celluloid sheets to be photographed and exhibited on film. Animation has been recognised as an artistic medium, specifically within the Entertainment#Industry, entertainment industry. Many animations are either traditional animations or computer animations made with computer-generated imagery (CGI). Stop motion animation, in particular claymation, has continued to exist alongside these other forms. Animation is contrasted with live action, although the two do not exist in isolation. Many moviemakers have produced Live-action animation, films that are a hybrid of the two. As CGI increasingly Photorealism, approximates photographic imagery, filmmakers can easily Compositing, composite 3D animations into their film rather than using practical effects for showy visual effects (VFX). ...

USA-10
USA-10, also known as Navstar 11, GPS I-11 and GPS SVN-11, was an American navigation satellite launched in 1985 as part of the Global Positioning System development programme. It was the last of eleven Block I GPS satellites to be launched. Background Global Positioning System (GPS) was developed by the U.S. Department of Defense to provide all-weather round-the-clock navigation capabilities for military ground, sea, and air forces. Since its implementation, GPS has also become an integral asset in numerous civilian applications and industries around the globe, including recreational used (e.g., boating, aircraft, hiking), corporate vehicle fleet tracking, and surveying. GPS employs 24 spacecraft in 20,200 km circular orbits inclined at 55°. These vehicles are placed in 6 orbit planes with four operational satellites in each plane. Spacecraft The first eleven spacecraft (GPS Block 1) were used to demonstrate the feasibility of the GPS system. They were 3-axis stabi ...

Cape Canaveral Space Launch Complex 17
Space Launch Complex 17 (SLC-17), previously designated Launch Complex 17 (LC-17), was a launch site at Cape Canaveral Space Force Station, Florida used for Thor and Delta launch vehicles launches between 1958 and 2011. Originally built in 1956, SLC-17 features two expendable launch vehicle (ELV) launch pads, SLC-17A and SLC-17B. The pads were operated by the 45th Space Wing and have supported more than 300 Department of Defense, NASA and commercial missile and rocket launches. History SLC-17 was built in 1956 by the United States Air Force for use with the PGM-17 Thor missile, the first operational ballistic missile in the arsenal of the United States. It was initially designed for testing suborbital launches of the Thor, in accordance to the IRBM's planned stationing in the United Kingdom as part of Project Emily. Pad 17A supported its first Thor missile launch on 3 August 1957, and Pad 17B supported its first Thor launch on 25 January 1957. As the Thor got wound down from ...

Cape Canaveral Space Force Station
Cape Canaveral Space Force Station (CCSFS) is an installation of the United States Space Force's Space Launch Delta 45, located on Cape Canaveral in Brevard County, Florida. Headquartered at the nearby Patrick Space Force Base, the station is the primary launch site for the Space Force's Eastern RangeCAST 1999, p. 1-12. with four launch pads currently active (Space Launch Complexes 36, 40, 41 and 46). The facility is south-southeast of NASA's Kennedy Space Center on adjacent Merritt Island, with the two linked by bridges and causeways. The Cape Canaveral Space Force Station Skid Strip provides a runway close to the launch complexes for military airlift aircraft delivering heavy and outsized payloads to the Cape. A number of American space exploration pioneers were launched from CCSFS, including the first U.S. Earth satellite (1958), first U.S. astronaut (1961), first U.S. astronaut in orbit (1962), first two-man U.S. spacecraft (1965), first U.S. uncrewed lu ...
