1 INTRODUCTION

At present, there is no international agreement with regard the definition of nano and microsatellites. However in practice, it is generally defined according to the weight of the Nano and microsatellite. In this paper, satellites between 1 and 100 kg are considered as nano and microsatellites as seen in the classification criterion used by NASA. Nano and microsatellites have many advantages, such as small size, light weight, good performance, short development cycle, low cost, flexible launch mode and so on. nano and microsatellites have been widely applied in areas such as communication, remote sensing, navigation and science exploration and have demonstrated economic and social benefits. Nano and microsatellites have become one of important development directions in space.

All space powers all round the world placed high value on the nano and microsatellite industry. The United States and Britain were the first two entering the field of nano and microsatellites. The University of Surrey manufactured the UOSAT“University Satellite” series and launched UOSAT-1 successfully in 1981, which set off a global upsurge in nano and microsatellite development and application. In 1993, the concept of nanosatellite was put forward by the United States. At present, the United States, Russia, France, Britain, Italy and other countries have established nano and microsatellite platforms or constellations. India, South Korea, Sweden, Denmark, Brazil, Spain, Israel and other countries have taken nano and microsatellite as the starting point to promote the development of space technology,thereby improving the overall strength of their space industries.In 2017, of the 473 spacecrafts launched worldwide, 316 nano and microsatellites accounted for 66.8% of the total number of spacecrafts[1]. In the future, with a large number of nano and microsatellites being launched, the framework of world space will be changed gradually.

China's nano and microsatellite industry started late. It began to develop rapidly until 2015, launching 30 nano and microsatellites. In 2018, the number of nano and microsatellites launched accounted for 46.2% of the total number of spacecraft launched by China. The nano and microsatellite field in China is changing from that of technology development to business development, and becoming a supplement to traditional satellites and even the main force in space innovation. Although China's nano and microsatellite industry has made great progress, there is still a long way to go to catch up with developed countries.Driven by the construction and operation of constellations, the next five to ten years will be the golden period for China's nano and microsatellites industry.
