Example Embodiment
[0027] Combine the following Figure 1 to Figure 3 , a preferred embodiment of the present invention is described in detail.
[0028] The current research results and on-orbit experience show that when the control accuracy is not high and the semi-major axis is mainly adjusted, it is often only necessary to complete the calibration of the one-way thruster. However, the current control tasks are becoming more and more complex, and the control accuracy requirements are also getting higher and higher, such as high-precision formation control tasks. At this time, the error caused by the thruster is the main part of the formation control error, but the formation control is often multi-pulse, and there is no applicable research result on the thruster calibration under the multi-pulse condition.
[0029] like image 3 As shown in the figure, the errors affecting the formation control accuracy are divided into two categories according to whether it is proportional to the control qua...
