Fujitsu's Technologies and Systems for Orbit Determination, Prediction, and Analysis
FUJITSU SCIENTIFIC & TECHNICAL JOURNAL(2017)
摘要
Advancements in space technologies have led to a broadening in the scope of exploration missions and in the operations of artificial satellites. Satellites now require precise orbit determination, prediction, and analysis using flight dynamics technologies, and the requirements for these technologies are becoming more and more complex, sophisticated, and diverse. Fujitsu has long participated in Japan's space exploration program and has made contributions to the development of orbital dynamics calculation systems for satellite operations. Our efforts continue today as we develop various systems such as orbit determination/prediction systems for reliably locating and tracking satellites and systems for precisely determining the orbits of space probes more than 400 million km from Earth. This paper presents the technologies and systems we have developed for determining, predicting, and analyzing the orbits of artificial satellites and space probes. The paper also describes relevant case studies and mentions the latest trends.
