摘要
随着用户对卫星导航系统需求的日趋膨胀,高精度差分技术已呈现出新的特征与发展趋势。本文从差分原理、技术、系统几个层面综合分析了现有差分系统的优缺点及发展趋势,在此基础上,探讨了我国卫星导航系统后续差分增强系统发展应关注的重点问题,并给出了几点建议。
With the increasing demand for satellite navigation system from users, high-precision GNSS differential technology has presented new characteristics and development trend. This paper made comprehensive analysis on the advantages, disadvantages and development trend of the current differential system from aspects of theory, technology and system. On this basis, key issues on the subsequent development of differential augmentation system in China were discussed with several suggestions.
