Abstract

In the space fields, technological innovations for next generation space systems have recently restarted again. The progress of digitization and software defined satellite in the communication satellites and the emergence of constellation systems using hundreds or thousands of small satellites are typical examples of these movements

There are 3 major fields in space business such as communication, earth observation and navigation. In the satellite communication field, “High Through Put”, “Digital Payload” and “Small  Satellite Constellation” are recent major directions. In the earth observation field,

“AI, Big Data Processing”,“Earth Observation Satellite Data Platform” and also “Small Satellite Constellation” are recent key words. In the navigation field, utilization of “High Precision Navigation” with “3D Digital Map” is key for future technology and business.  In Japan, QZSS(Quasi Zenith Satellite System) has started to provide regional satellite navigation service since 2018. QZSS  provides “High Precision Navigation” service by CLAS(Cm Level Augmentation Signal)  and utilization for automated driving, IT agriculture and etc. are presently investigating.

In this lecture, these recent and future technological trends and business directions will be presented after brief introduction of space related activities of Mitsubishi Electric Corporation.
