Abstract: Microcomputer Telemetry data receiving and processing system (MTDRPS)mainly consists of a BCM-1 microcomputer system and a single board computer with 8 bits word length. With the receiving devices of the ground stations, MTDRPS can receive and process the compressed telemetry data. The system has two main features: 1. The data receiving buffer is used and the serial telemetry data receiving and parallel data storing are processed by two microcomputers respectively. 2. By using the software method the synchronism was performed
