The system will be used for a small satellite called KITSAT-3. Among many advantages of the use of small satellites, the feasibility of the development of a simple and low cost ground receiving station is one of the most meaningful as far as the ground segments concerned. The moderate speed of small satellites makes it possible to replace expensive dedicated hardware by cheap commercial Personal Computers and dedicated software. In order to develop a low cost direct archiving system, a PC interface card was developed. This card converts incoming stream into parallel words and store them into the hard disk of a PC. For frame synchronization process, a dedicated software was developed. The techniques used for this development are not very complicated, which proves the advantage of the use of small satellites. Although the system developed here has the fundamental limitation of the speed of incoming data stream, the system upgrade should be done also without great difficulties with the fast advancing PC technologies. 1. INTRODUCTION satellites can reduce the size and complexity of the ground receiving station significantly. With this, the A earth imaging satellite takes pictures of the earth development of low cost receiving station is very feasible. surface and usually stores a large amount of data onboard recorder. When the communication link between the satellite and the ground receiving station is set up, the In this paper, the development of a low cost direct image data stored onboard are transmitted to the archiving and preprocessing system will be described. receiving antenna of the ground station. After reception, This system will be used for a small satellite called appropriate operations should be carried out to restore KITSAT-3. The KITSAT-3 is the third satellite of the proper image data and these image data should be KITSAT series manufactured by Satellite Technology stored in real-time. Research Center of KAIST, Korea. As this satellite has a down-link speed of 3Mbps, the conventional (expensive) The development of such ground receiving system is dedicated hardware can be replaced by a commercial often very complex and difficult as image data are computer hardware. The cost effectiveness can be usually very bulky and the data rate from the satellite to achieved by avoiding the dedicated hardware and, the ground station is very high. To handle this high speed instead, developing dedicated software. data, dedicated hardware such as High Density Tape Recorder (HDTR) and Frame Synchronizer have been This paper will start with general description of the developed and used for commercial remote sensing KITSAT-3 ground receiving system.
