Space Defense Center
The Space Defense Center (SDC) was a space operation center of the North American Aerospace Defense Command. It was successively housed at two Colorado locations, Ent Air Force Base, followed by Cheyenne Mountain's Group III Space Defense Center The 1st Aerospace Control Squadron manned the SDC at both locations, which used the Electronic Systems Division's 496L System for processing and displaying data combined from the U.S. "Air Force's Space Track and the Navy's Spasur" ( NAVSPASUR). The photo is of a console introduced for the 427M system, the 496L inputs were only card readers and paper tape readers, the only output was from two large line printers. History The initial 496L System was at Hanscom Field's National Space Surveillance Control Center and the second was installed at Ent Air Force Base's Space Defense Center. The Ent SDC was one of several facilities providing data to the Cheyenne Mountain Combat Operation Center when the nuclear bunker achieved full operational ...

Space Defense Operations Computation Center, NORAD
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the ''Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called ''khôra'' (i.e. "space"), or in the ''Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of place" as "space ...

Source Lines Of Code
Source lines of code (SLOC), also known as lines of code (LOC), is a software metric used to measure the size of a computer program by counting the number of lines in the text of the program's source code. SLOC is typically used to predict the amount of effort that will be required to develop a program, as well as to estimate programming productivity or maintainability once the software is produced. Measurement methods Many useful comparisons involve only the order of magnitude of lines of code in a project. Using lines of code to compare a 10,000-line project to a 100,000-line project is far more useful than when comparing a 20,000-line project with a 21,000-line project. While it is debatable exactly how to measure lines of code, discrepancies of an order of magnitude can be clear indicators of software complexity or man-hours. There are two major types of SLOC measures: physical SLOC (LOC) and logical SLOC (LLOC). Specific definitions of these two measures vary, but the most c ...

Space Detection And Tracking System
Space Detection and Tracking System, or SPADATS, was built in 1960 to integrate defense systems built by different branches of the United States Armed Forces and was placed under North American Aerospace Defense Command (NORAD). The Air Force had a program called Spacetrack, which was a network of space-probing cameras and radar. The Navy had a system called SPASUR, a space surveillance system that was "an electronic fence" the protected the southern United States. SPADATS was developed by the SpaceTrack Research and Development Facility, also called the 496L System Program Office, at Hanscom Field in Bedford, Massachusetts. ( Bendix, Sperry Rand and Hughes competed for SPADATS contract in the early 1962 on the basis of their prior experience in phased array technology.) It first operated at the Electronic Systems Command building at Hanscom and in 1963 was transferred to the Ent Air Force Base and then to the Cheyenne Mountain Complex in 1965 or 1966. From that point, the SpaceTrac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Space Surveillance Network
The United States Space Surveillance Network (SSN) detects, tracks, catalogs and identifies artificial objects orbiting Earth, e.g. active/inactive satellites, spent rocket bodies, or fragmentation debris. The system is the responsibility of United States Space Command and operated by the United States Space Force. Space surveillance accomplishes the following: * Predict when and where a decaying space object will re-enter the Earth's atmosphere; * Prevent a returning space object, which to radar looks like a missile, from triggering a false alarm in missile-attack warning sensors of the U.S. and other countries; * Chart the present position of space objects and plot their anticipated orbital paths; * Detect new artificial objects in space; * Correctly map objects traveling in Earth orbit; * Produce a running catalog of artificial space objects; * Determine ownership of a re-entering space object; * Inform NASA whether or not objects may interfere with the International Space S ...

Air War College
The Air War College (AWC) is the senior Professional Military Education (PME) school of the U.S. Air Force. A part of the United States Air Force's Air University, AWC emphasizes the employment of air, space, and cyberspace in joint operations. Headquartered at Maxwell Air Force Base in Montgomery, Alabama, its higher headquarters is the Air Education and Training Command (AETC) at Randolph Air Force Base in San Antonio, Texas. It is one of six war colleges within the U.S. Department of Defense's Joint Professional Military Education (JPME) Phase II Education Program for commissioned officers. History The Air War College was founded in 1946 by the United States War Department (subsequently merged with the Navy Department to form the Department of Defense) as a U.S. Army Air Forces program at what was then Maxwell Field. The college has operated continuously since its founding except for a period of six months during the Korean War. AWC operates alongside the Army War Colle ...

United States Strategic Command
United States Strategic Command (USSTRATCOM) is one of the eleven unified combatant commands in the United States Department of Defense. Headquartered at Offutt Air Force Base, Nebraska, USSTRATCOM is responsible for strategic nuclear deterrence, global strike, and operating the Defense Department's Global Information Grid. It also provides a host of capabilities to support the other combatant commands, including integrated missile defense; and global command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR). This command exists to give "national leadership a unified resource for greater understanding of specific threats around the world and the means to respond to those threats rapidly". Mission statement USSTRATCOM employs nuclear, cyber, global strike, joint electronic warfare, missile defense, and intelligence capabilities to deter aggression, decisively and accurately respond if deterrence fails, assure allies, shape adversary b ...
