Automatic computer controlled testing of spacecraft and experiments

Abstract

This paper describes the AUTOTEST system, a large-scale real-time testing system that was originally designed to test the Atmosphere Explorer spacecraft and experiments. It is noted that AUTOTEST is a flexible, fully automatic, programmable system that is externally controlled by a mnemonic test language and can be operated manually as well as automatically. The use of spacecraft simulators in this system is described together with the software and a sample test program. Advantages of AUTOTEST in terms of operational simplicity and low costs are discussed.
