针对传统的司托克斯积分方法计算量大、模型复杂的缺点,通过将地球球面以适当的经纬度差进行划分及合理简化,实现了司托克斯积分法计算外部空间扰动引力的积分方程的离散化,建立了地球扰动引力的快速计算模型,并在快速计算模型的基础上采用并行计算技术,实现扰动引力的实时计算。仿真结果表明,提出的快速并行计算模型能较好地实现地球扰动引力的快速、高精度计算。

Research on Parallel Method for the disturbing gravity of the outside space

As the traditional Stokes integral method has the shortcoming of great amount of computation and complicated calculating model, this paper proposes a fast calculating model of the Stokes integral method to calculate the disturbing gravity of outside space, discretizing the Stokes integral equation by partitioning the earth sphere in both latitude and longitude direction and reasonable simplification. At the same time, the technology of parallel computing is used to implement the fast algorithm. By the simulation, it is proved that the disturbing gravity can be fast calculated, using the fast algorithm proposed by this paper.
