Abstract: The solar array drive assembly is a key single machine for a three axis stable satellite, driving the solar array to orient towards the sun and transmitting electrical power to the entire satallite, whose reliability and lifespan directly affect the lifespan of the entire satellite. From the 1960s, after decades of development, significant progress has been made in transmission power, inorbit lifespan, reliability and low disturbance characteristics. In the past decade, with the development of low orbit satellite constellations and commercial aerospace, a strong demand for low cost, lightweight and dual axis configuration products has been displayed. This article summarizes the technological development direction and model application characteristics based on information from relevant fields, and proposes that the ultrahigh voltage and high power technology, as well as the the commercial aerospace application of low cost technology are the main development directions for the future. the future development trends.
