Abstract

The observed science data generated by all the instruments of the Space Solar Telescope (SST) is about 1728 Gbyte per day, after preprocessing the data volume is about 50 Gbyte, the data then access into the Mass Memory (MM) where the offline compression will reduce the data size advancely to about 10 Gbyte and the compressed data will be transmitted down once the SST contacts with the ground station. Because the MM takes the core position in the data stream transmission, it is the key to the design of the onboard data handling system. In addition, the bit error detection and correction and redundancy are needed for increasing the reliability in the special outer space environment. A ground model MM has been made which performs the main functions for the system. The desired goals are attained by the experiment.
