Abstract

Formatting process of earth observation satellite downlink data is often used by custom made hardware which designed for one satellite or a sensor. However, in the near future lunch of various kinds of multi sensor satellite such as ADEOS-2 are planned. If we make hardware for each sensor for format processing, it the system, and operation becomes very complicated. It also causes degradation of reliability of the format processing system. This is a very big problem. We have developed a software based downlink data formatter which solved these problems. The hardware dependency was reduced and made multiusable high speed processing was realized.
