A Survey of Precision Formation Relative State Measurement Technology for Distributed Spacecraft

High-precision relative-state measurement technology is one of the key technologies for achieving precision formation flying distributed spacecraft. This paper conducts a comprehensive analysis formation-flying projects spacecraft in various countries. In context practical application, specific mission configuration, orbit distribution, technology, and payload project are summarized. On this basis, relative state techniques outlined first time, using non-autonomous techniques, autonomous new composite techniques. A detailed GNSS (Global Navigation Satellite System)—relative measurement, laser infrared RF visible light visual multiple methods conducted. The applicable scenarios each method thoroughly discussed from several aspects, such as technical scheme, system design, accuracy requirements, advantages, shortcomings. addition, proposes concept adopting multidisciplinary optimization architecture perspective overall design It enables selection property indicator optimization, on premise optimizing performance. Finally, direction future development trend flight established.
