On May 24,2019,the first batch of Starlink satellites was launched into orbit,and by the end of 2023,over 5 500 Starlink satellites had entered orbit.However,such a large-scale low-orbit constellation has caused significant disturbances to other operational satellites,especially the stable operation of space stations,due to the large orbit errors of Starlink satellites(sometimes up to tens of kilometers).Currently,the publicly available orbit data sets contain the most orbit information of space targets in two-line element(TLE)data.This study analyzes the accuracy of TLE data for Starlink satellites and proposes methods to improve the accuracy of TLE orbit predic-tions for different phases of Starlink satellites,including the ascent,stable,and descent phases,and conducts per-formance analysis.The findings of this study can be applied to the orbit prediction analysis and optimization of TLE data for various satellite constellations or space debris.
