惯性定位测量重力空间参数的逼近计算与工程实践

Approach Method and Project Practice of Inertial Oriented Survey Gravity-space Parameters

针对我国惯性定位测量的现状,根据地面重力异常与地形数据密的强相关特性,研究探讨了利用高分辨率地球重力场扰动位模型和地形数据快速求取重力空间参数的计算模型,并通过工程实践证明了其实用性,对实现惯性测量完整定位具有重要的应用价值。

Based on the inertial oriented survey actuality of my country, and the strong correlation between ground gravity anomaly and terrain data, this paper presents the quick method of calculating gravity-space parameters using high-resolution geopotential model and terrain data. The utility of this method is proved by the project practice. It is important to realize the full orientation of inertial survey.
