Abstract :
Describes the application of a single-chip microcomputer in a high-altitude balloon instrumentation system. The system, consisting of a magnetometer, a stepping motor, a microcomputer and a gray code shaft encoder, is used to provide an orientation reference to point a scientific instrument at an object in space. The single-chip microcomputer, Intel´s 8748, consisting of a CPU, program memory, data memory and I/O ports, is used to control the orientation of the system.
