The TRIAD satellite provided APL with its first opportunity to fly a general-purpose digital computer. The paper presents the system of software that was written to develop, test, and operate the APL-designed TRIAD computer. After a description of the machines real-time flight requirements and its physical properties, the major software projects are discussed. These include the formulation of Programming language, called ARTIC, and an associated assembler special-purpose diagnostic and utility programs a real-time simulation of the expected satellite hardware environment an in-flight operating system, called LDR, capable of coping with various real-time operational demands. Lastly, the actual performance and utility of the computer after launch is summarized. TRIAD exemplifies the value of a small, programmable computer in managing and supporting complex satellite missions. Author
