Chow, working for the Arma Division of the American Bosch Arma Corporation, pioneered the use of digital computers in missile, satellite and spacecraft guidance systems, leading the design of the United States Air Force Atlas E/F ICBM (Inter-Continental Ballistic Missile) all-inertial guidance system and guidance computer, the first production ...
Part of MADDIDA at Computer History Museum. The MADDIDA (Magnetic Drum Digital Differential Analyzer) was a special-purpose digital computer used for solving systems of ordinary differential equations. [1] It was the first computer to represent bits using voltage levels and whose entire logic was specified in Boolean algebra. [2]
1957 - Launch of the first ICBM, the USSR's R-7 (8K71), known to NATO as the SS-6 Sapwood. 1957 - The USSR launches Sputnik 1, the first artificial satellite. 1958 - The U.S. launches Explorer 1, the first American artificial satellite, on a Jupiter-C rocket. 1958 - US launches their first ICBM, the Atlas-B (the Atlas-A was a test article only).
The D-17B (D17B) computer was used in the Minuteman I NS-1OQ missile guidance system. The complete guidance system contained a D-17B computer, the associated stable platform, and power supplies . The D-17B weighed approximately 62 pounds (28 kg), contained 1,521 transistors , 6,282 diodes , 1,116 capacitors , and 5094 resistors .
Autonetics was a division of North American Aviation that produced various avionics but is best known for their inertial navigation systems used in submarines and intercontinental ballistic missiles. Its 188-acre facility in Anaheim, California , with 36,000 employees, [ year needed ] was the city's largest employer. [ 1 ]
His first models were designed in the early 1930s, but in 1932 his first version of the E-6B, originally known as the "Dalton Dead Reckoning Computer", came into existence. [ 2 ] On October 30, 1940, Dalton was recalled to active duty and assigned to Naval Air Station Anacostia , across the river from Washington, DC, to help train naval aviators.
Some of the earliest computers were military computers. Military requirements for portability and ruggedness led to some of the earliest transistorized computers, such as the 1958 AN/USQ-17, the 1959 AN/MYK-1 (), the 1960 M18 FADAC, and the 1962 D-17B; the earliest integrated-circuit based computer, the 1964 D-37C; as well as one of the earliest laptop computers, the 1982 Grid Compass.
She was a pioneer of computer programming. Hopper was the first to devise the theory of machine-independent programming languages, and used this theory to develop the FLOW-MATIC programming language and COBOL, an early high-level programming language still in use today. She was also one of the first programmers on the Harvard Mark I computer ...
