However, due to signal occlusion, reflection and other factors, the accuracy and reliability of GNSS are limited in real environment. To solve this problem, traditional navigation methods often adopt single GNSS positioning technology, which cannot meet the requirements of high accuracy and reliability. Therefore, the combination navigation technology has gradually become a research hotspot, which combines the information of multiple sensors to improve the accuracy and reliability of navigation.精品文档---下载后可任意编辑This paper aims to study the GNSS combination navigation algorithm and its implementation, including the following aspects:1.
