为了改善土星系统第九颗卫星菲比的轨道，我们的研究小组于2003年利用安装在上海天文台佘山站1.56米天文反射镜上的大尺寸(2048×2048像素)CCD探测器进行了101次新的观测。我们将其轨道的数值积分与从1904年到2003年收集的所有地面天体测量观测数据进行了拟合，其中包括来自乔唐和彭等人的最新精确数据集。得到了一组新的菲比初始条件，从而改善了这颗卫星的轨道。
In order to improve the orbit of Phoebe, the ninth satellite of the Saturnian system, 101 new observations were made by our research team in 2003, using a CCD detector of large size (2048×2048 pixels) mounted on the 1.56 m astrometric reflector at the Sheshan Station of Shanghai Astronomical Observatory. We fitted a numerical integration of its orbit to all of the collected Earth-based astrometric observations from 1904 to 2003, including the newest precise data sets from Qiao & Tang and from Peng et al. A new set of initial conditions of Phoebe has been obtained, leading to an improved orbit of this satellite.
