[0036] In order to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0037] The invention proposes to apply the master-slave star velocity measurement mode in asteroid detection. Specifically, the ground-based deep space station keeps track with the probe A (master star) orbiting the asteroid, and at the same time probe A and probe B (slave star) orbiting the same asteroid perform two-way speed measurement, such as figure 2 shown. The advantage of this observation mode is that real-time measurements are performed between the master and slave stars without over-reliance on ground-based deep space stations. The high-precision velocimetry data of the master and slave stars are more sensitive to the asteroid's gravitational field. The topographical changes of asteroids can be directly reflected in the observed quantities of velocity. ...
