The Orbiting Geophysical Observatory Test Program

This paper introduces the Orbiting Geophysical Observatory Spacecraft and the electrical and mechanical checkout procedures and equipment used in its qualification and acceptance testing. The Integrated Systems Test approach incorporating semi-automatic test programming and spacecraft evaluation is described after disclosure of previous test cycles and the test program objectives. Specific tests on the attitude control, power, and communications and data handling spacecraft subsystem are discussed, with consideration of mechanical handling and test fixtures.
