Abstract

A new algorithm for geophysical map-aided navigation is proposed. It does not require any preliminary estimation of the field measured along the vehicle trajectory and, as consequence, does not need any stochastic field model. The algorithm uses a whole set of the available geophysical field measurements. The accuracy analysis procedure applied to estimate the effectiveness of the proposed algorithm is described. The features and advantages of this algorithm are illustrated by an example of marine gravity-aided navigation.

一种无需现场测量预处理的地图辅助导航算法

摘要

提出了一种新的地球物理地图辅助导航算法。它不需要对沿车辆轨迹测量的场进行任何初步估计，因此不需要任何随机场模型。该算法使用了一整套可用的地球物理场测量结果。描述了用于估计所提出算法的有效性的准确性分析过程。通过一个海上重力辅助导航示例说明了该算法的特点和优势。
