Abstract: he principle and configuration of a signal source of oscillatorilly scanning infared earth sensor for geostationary satellite are given, and the method of software development is presented. Through simplification and improvement of the computation process, the software makes full use of the hardware resource, especially the 8031 microprocessor. The performance of the signal source is enhanced, and the requirement for the signal source's real-time operation is reached.
