The mystery of the asteroid (4179) Toutatis was revealed by Chang'e-2 spacecraft during a close flyby on December 13, 2012. Optical imaging and navigation of the probe during the flyby were performed entirely under ground-based radio tracking and default sequence built on ground. This paper establishes a set of estimation algorithms of the relative trajectory between Chang'e-2 and Toutatis based on...
On December 13, 2012, China's Chang'e 2 Spacecraft successfully flew past No.4179 Asteroid Toutatis, and acquired a series of clear optical images concerning Toutatis. The data obtained is very important for us to be able to establish feasible methods for deep-space optical navigation. However, as the fly-by process cannot be repeated and deep-space environments cannot be tested using physical platforms...
