In this paper a new semi-analytical and semi-numerical method for computation of the second order perturbation of artificial earth satellites is presented. Its basie ideas are the following 1. In our analysis, we adopt σ* as the fundamental elements system, where σ*'s are mean elements, obtained after subtracting the short, period terms △σ_s. from the oscula-ting elements. 2. The σ*'s secular and long period rates (up to third order) are derived with the numerical averages of dσ/dt, which are the rates of the osculating elements. 3. The osculating elements in computing dσ/dt are calculated with σ* plus the dt short period terms △σ_s, in which the first order short period terms △σ_s are obtained by analytical method, and the second order ones △σ_s by Fourier analysis. Because of adopting σ~* as the elements system, we have overcome some shortco-mings in the numerical method, such as the shorter step, the longer computing time, the more serious accumulatation of errors, etc. As we compute dσ~*/dt and △σ_s by means of numerical method, we have avoided the development of the complicate for-mulae. In this way, our method also has the advantages of simpler computing for-mulae and more convenient programming. To compute the second order perturbation, the computing time of our method is only 1/10 of the classical numerical method, and the memories is about 1/5 of the pure analytical method. The numerical method of ODE are also discussed. An improved Chebychev itera-tion process is developed to adapt the need of the orbit determination in satellite dynamical geodesy. In this paper we also give detailed formulae for computing the perturbating forces and the numerical results of computation by our method. The numerical results show that the errors in radius and across-track are less than 0.1 m, and that in along-track less than 1 m.

本文提出了一种新的计算人造卫星二阶摄动的半分析、半数值方法,其基本思想是: i),采用σ~*作为基本根数系统;这里σ~*是从密切根数σ中扣去短周期项△σ_s的平根数。 ii),σ~*的长期、长周期变率(准到三阶)由密切限的变率dσ/dt的数值平均求得。 ii),计算dσ/dt中所用的密切根数σ,由σ~*加上短周期项△σ_s,而得,其中一阶短周期项△σ_s~((1))用分析公式计算,二阶短周期项△σ_s~((2))用Fourier分析方法求取。由于采用了σ~*作为根数系统,克服了密切根数σ数值方法的积分步长短、计算时间长、积累误差大等缺点;由于dσ/dt、△σ_s~((2))用数值方法计算,又避免了繁复的公式推导,兼得了计算公式简单,程序编制方便等优点。用本方法计算二阶摄动,计算时间比经典的数值方法要节省十分之九,所占内存的大小可比分析方法节省4/5—5/6。本文还讨论了微分方程的数值积分方法,改进了迭代过程,使得它更适合于卫星动力测地中测轨的要求。本文还给出了用本方法计算的数值结果。数值结果表明:用本方法测轨,向径、垂迹方向误差小于0.1米,沿迹方向误差小于1米。

Comet Tsuchinshan (1977q) was discovered at Purple Mountain Observatory on Nov. 3, 1977. The osculating orbital elements (referred to the barycenter of the sun and Mercury) given in table 1 are derived from 42 observations Nov. 3, 1977 to Jan. 10, 1978 at our observatory and abroad, taking into account the perturbations of all major planets. In all the observations the rms residual is 1."78. Our observations are also published in table 2. With the elements thus obtained, the appropriate ephe-merides in recent years have been calculated and listed in table 4. And then, in consideration of accurate perturbations, we compute the original and future orbits (referred to the center of mass of solar system) while the comet is about 60 A. U. from the Sun. The results that both the original and future orbits are hyperbolicaare given in table 5 and may be compared with the osculating elements. Nevertheless, the two months observed interval for determining orbit is short. In order to obtain the more reliable conclusion, it is necessary to make some efforts for increasing the obser-ved arc.

We investigate in this paper a principal approach to solve the perturbation equations of the Vinti's intermediary and propose a practical semi-analytical and seminumerical method based on the average elements method. We define the average elements by the Hori's average technique. The definitions of the average elements σ~* and the short period terms Δσ_s are:Here σ is the osculating elements, T is a satellite motion period, t~* is the intermediate time variable. The Δσ_s (up to third order) are derived by-Fourier analysis and the dσ~*/dt (up to fourth order) can be computed by the numerical average method. This method can be used to reduce satellite laser observations with the accuracy coming in the range of centimeters.

本文研究了Vinti型中间轨道摄动方程的原则解法,提出了一种有实用意义的半分析、半数值方法。用的基本手段是平均根数法,平均根数σ~*及短周期项△σ_s的定义为:这里,σ为密切根数,T为卫星运动周期,t~*为虚拟时间变量。短周期项△σ_s(准到三阶)可用Fourier分析方法求得,而百(dσ~*)/(dt)(准到四阶)则用数值平均方法计算。本方法可用来处理高精度的卫星激光观测。
