AverStar

AverStar, formerly Intermetrics, Inc., was an American software company founded in Cambridge, Massachusetts in 1969 by several veterans of the Massachusetts Institute of Technology Instrumentation Laboratory who had worked on the software for NASA's Apollo Program, including the Apollo Guidance Computer. The company specialized in compiler technology. It designed and implemented the HAL/S programming language, which was used to write the Space Shuttle Primary Avionics Software System. It took part in the design effort that led to the Ada programming language, designed the Red language, one of the finalists in the Ada design competition, and wrote one of the first production-quality Ada compilers; the large-scale Ada 95 revision of the language was designed at Intermetrics. In the 1970s it also developed the CS-4 language for the United States Navy as an extension of CMS-2. Intermetrics merged with Whitesmiths Ltd. in December 1988 and with the game developer Looking Glass Studios in 1997. In 1998 it acquired Pacer Infotec and renamed itself AverStar, which merged with the Titan Corporation in March 2000; Titan was in turn acquired by L-3 Communications in 2005.
