This paper presents a test used to measure performance with laboratory testing of the computerized system. The Starlab Pointing Control System incorporates an advanced flight computer design. This computer intermeshes analog loops of its mirror controlling servos. Digitally derived transformation relationships are introduced to the analog channels with solid state multiplying digital analog converters (MDACs). The control system distributes commands to a two axis pointing gimbal and fast servo mirrors to control a line of sight that is dependent on measurements made with focal plane detectors responding to space object radiation. An approach to the system hardware and software testing has been developed. The test includes verification of optical tracking, including space object imagery and the beam control mirror servos. Flight computer software is incorporated into the computer to allow functional checkout of its algorithms. In addition a special hardware/software test set has been developed to provide the hardware flight computer system with an emulated hardware and flight dynamic environment. The test set is a special purpose hardware system supported by an external computer for supplying an emulated interface of the starlab actuators, sensors, and effective geometry line of sight conditions corresponding closely to the physical environment of a Starlab mission. Its primary purpose is to check out the flight computer system. Its secondary purpose is to perform 'system test' and mission simulations of the pointing control system. These tests are used to validate experiment design, support laboratory hardware integration.
