小行星是太陽系最重要的一類小天體,主要分佈在兩個區域;火星和木星軌道之間的一條主帶和近地空間.近地小行星軌道的最大特點是其軌道半長徑與地球軌道半長徑相近,或近日距離接近甚至小於日地平均距離,其運動可深入到地球軌道的內部,這將導致該類小行星與地球(還有金星、火星等)十分靠近甚至發生碰撞.這一特徵給其軌道演化數值研究帶來一些困難,包括天體力學方法中一般消除碰撞奇點的正規化處理以及對定性研究十分成功的辛演算法都將在不同程度上失效.通過對幾種常用數值方法(包括辛演算法)計算效果的比較,根據小天體運動自身的特性,給出了相應處理措施,從而可提高計算結果的可靠性Thirdly, an ideal satellite orbit is simulated, and on this foundation, we establish some typical simulation and testing circumstances. lastly, after simulation in the simulation and testing circumstances, we compare the performance of ukf and ekf. and then, based on the outdoor experiment of the vehicle, an analysis and contrast between our simulation results and commercial data process software is carried out, and the conclusion is obtained
