A Study of the Navigation Technology and Application Based on Astronomical Spectral Velocity Measurement

With the development of aerospace technology, the requirements of spacecraft navigation system for the accuracy, autonomy, real-time and other comprehensive performance are increasingly high. As a new type of autonomous navigation technology proposed in recent years, astronomical spectrum velocimetry navigation has the characteristics of direct acquisition of spacecraft speed information, great real-time performance, high velocity measurement accuracy, it has broad application prospects. In this paper, on the basis of combing the research progress of astronomical spectral velocimetry navigation in recent years, proposed a number of application combinations of astronomical spectral velocity measurement and navigation technology. Based on the needs of the current space mission and research difficulties, combined with the domestic and foreign technical trends and the actual engineering demamds, the future key research direction and content of astronomical spectral velocity measurement and navigation technology is pointed out. Astronomical spectral velocimetry navigation provides a new technical approach for the mission navigation of space exploration engineering. The continuous research on astronomical spectral velocity measurement navigation technology will effectively promote the development of navigation technology, and enhance the theoretical research ability and engineering development level of astronomical navigation.
