| 内容記述 | The emergence of commercial space, the growing use of space by universities and emerging countries, as well as the adoption of reduced-cost missions by national space agencies have boosted the use of small satellites with a wide range of innovative concepts and in some cases ambitious plans ranging from Earth orbit to deep space missions. Small satellite missions are characterized by a fast development process and low cost, in order to provide service for the end-users, whether commercial or non-commercial. These characteristics impose constraints on the small satellite manufacturers and developers to follow a different path from the traditional space design, development and operation phases. One such difference relies on the use of commercial-off-the-shelf （COTS） parts, especially for the electrical, electronic, and electro-mechanical （EEE） components, as well as new materials that are used to build the different satellite subsystems. The use of COTS combined with a reduced lifetime of the missions and the increased in launch opportunities has enabled the growing of a commercial industry market that is predicted to reach $37 000 million USD by the year 2027. On the other hand, independently of the design strategy approach （traditional space or new space）, all spacecraft have to be able to survive the launching environment and the natural space environment. For the last one, the space weather as the study field of the Sun-Earth environment its effects are also considered as one of the main hazards to modern human technology, which can affect assets located through all the Earth’s magnetosphere and on the plant’s surface. Therefore, space weather is important from the basic science perspective and from the pragmatic point of view as it impacts human society. For artificial satellites operating in space, the technologies involved in their systems are constantly exposed to energetic particles mainly from the solar origin and from the galaxy. As small satellites facilitate the use of new technologies on-board, the adoption of a different strategy for the assessment, testing, and validation of new devices, materials and architectures is a fundamental step towards a mission to be successful. In this context, the present thesis addresses a methodology for in-flight testing and evaluation from direct measurements of the charged particles environment inside a small satellite. The case of study is based on the development and operation of the Ten-Koh satellite, where the orbit, satellite size and its structure made of composite materials represent a good opportunity for validation. As a means of achieving the research aims, the following studies have been done: ・Study comparison of the different design strategies implemented by traditional satellite development and small satellite development. ・Environmental models prediction variability and its impact on the satellite mission and systems design. ・Design of an experiment for measuring the charged particles environment inside a micro-satellite in a Sun-synchronous orbit. ・Preparation and operation of the high-energy electrons and charged particles main mission on-board the Ten-Koh satellite to perform measurements in orbit. ・Processing of the received mission data from the Ten-Koh CPD payload. ・Results interpretation from the Liulin detector. The results are presented together with an evaluation of the space weather effects that the Ten-Koh satellite experienced in orbit. | |||||||
