摘　　要：根据天王星卫星的运动理论模型（GUST86），建立了一套5颗主要卫星的星历表计算和误差分析程序。对部分高精度卫星观测位置资料进行的O－C计算和分析表明了计算程序的正确性和实用性。Laskar (1986) built a general analytical theory for the five satellites of Uranus denoted by GUST (General Uranus Satellite Theory) including the first time short -periodterms plus long-period terms apart from the Laplacian inequality, which is the only termtaken into account in the exising classical theories. Laskar claimed that the internal accuracy of the theory was estimated to a few tens of kilometers. On the basis of the new theory, a Fortran 77 routine was completed to produce the ephemerides for the five uraniansatellites and give estimation of the errors. In order to test the program, the residuals ofthe observed-minus-computed (O-C) was abtained by fitting the theory to 2 600 photographic observations of high precision from 1982 to 1985. The results from the reductionshow GUST to be of small standard error and the routine realiable.
