Abstract
The application and technological development of geosynchronous orbit(GSO) small satellite are researched in this paper. Firstly the application field and application value of GSO small satellites are analysed. Secondly, the technology development status of foreign GSO small satellites is overviewed. Then the differences and similarities among GSO small satellite, traditional large satellite and low earth orbit(LEO) small satellite are compared, and characteristic and key technique are systematically studied. Finally, for China’s future military and civilian needs, combined with the development trend of modern small satellite technology, the preliminary proposal for the development of China’s GSO small satellite are given.
Highlights
Since the U.S military put forward the concept of modern small satellite in the 1980s, small satellite has become an important direction of spacecraft development due to its advantages of light weight, good performance, short development cycle and low cost
There is no fundamental difference between GSO small satellites and low Earth orbit (LEO) small satellites, but the mission requirements and application occasions of them are different
Because of its civil and military value, GSO small satellite has gradually become a trend of future satellite development
Summary
Since the U.S military put forward the concept of modern small satellite in the 1980s, small satellite has become an important direction of spacecraft development due to its advantages of light weight, good performance, short development cycle and low cost. GSO small satellite has attracted more and more attention. Their application fields mainly include: close monitoring of GSO spacecraft, reconnaissance of GSO spacecraft, inorbit maintenance for large GSO satellites, and countermeasures against GSO spacecraft. There is no fundamental difference between GSO small satellites and LEO small satellites, but the mission requirements and application occasions of them are different. The different mission requirements lead to differences in design of GSO small satellites and LEO small satellites. In order to satisfy the mission requirements, the GSO small satellites should have some advantages. The rapid, economical and efficient GSO small satellites research and development process, the large angle attitude maneuvering ability and orbit maneuvering ability, and so on. The conclusion gives preliminary proposal for develop of China GSO small satellites
