Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a method for unbiased flight control of a satellite's nominal orbit. Background technique [0002] Facing the future, a large number of cutting-edge disruptive applications such as high-precision military remote sensing, high-precision navigation, and electromagnetic space reconstruction have put forward unprecedented demands on the high-precision and long-term autonomous navigation capabilities of space nodes. According to the existing model, the cost of building a spatial benchmark is huge, and the accuracy is still limited by the bottleneck of dynamic constraints. Therefore, it is necessary to rethink the construction style of high-precision spatial nodes and explore new principles of autonomous navigation. In order to improve the accuracy of the space reference, it is necessary to build an ultra-high-precision space reference station satellite to achieve the highest precis...
