Abstract:In order to solve the problem of low efficiency in calculating vertical deviation in large-scale and high-resolution regions by using the super-high-order earth gravity field model, this paper presents an array dimension-lifting and zoning methods based on OpenMP multi-core parallel technology. Experiments show that the acceleration ratio of this method to calculate vertical deviation is up to 5.6 times, which greatly improves the calculation efficiency of super-high order vertical deviation, and provides ideas for solving similar fast calculation problems in data processing of gravity field.
