With the development and the maturity of modern small satellite technology, it is promising and significant to use the new technology for the Remote Sensing. The paper presents a set of adaptive forward error correction coding theme and finishes analysis and design for the satellite-earth communication control unit in the light of error control coding and decoding principle and corresponding high level data link control. We do an experiment using the CCD photographic image of 1632×1032 array at noisy channel. The statistics of the experiment result indicate: Applications of error control technique enhance the reliability of the downlink of telemetry parameters such as satellite down-link state, orbit, satellite-borne computer and of photographic image data of CCD camera. 1. PREFACE The modern small satellite, which was developed in the middle of 1980s, is growing promptly in the world and applied widely in commerce and civilian by reason of its many remarkable characteristics such as multiple use, small size, light weight, low cost, short development period, flexible orbit setting and convenient launching etc. Additionally, the Surrey University in British, a representative of small satellite development, an
