One of our most notable
customers is the Naval Research Laboratory
in Washington D.C. We have completed a contract to the Naval Research
Laboratory's (NRL) Naval Center for Space Technology (NCST) to produce
a control system for the Advanced Systems Controller (ASC) program. The
ASC uses a Honeywell GVSC 1750A processor (TLD Ada Compiler) along with
a 1553 Command and Telemetry Bus to provide command, control and monitoring
of the spacecraft. This spacecraft controller was designed to support autonomous
operations for a period of 180 days. Based on its success in this application,
SCL is now the standard command language and expert system for flight software
systems. This software was the basis for the Clementine
Flight Software.
