GNSS差分与完好性技术体系架构

GNSS Differential and Integrity Technology Architecture

对目前国内外现已存在的各种GNSS差分与完好性技术以及增强技术进行了全面梳理和比较分析，对GNSS增强目标和性能进行了深入探讨。从全球基本层、广域增强层、局域增强层和用户终端层等几个层面提出了GNSS差分与完好性技术体系架构，为中国GNSS增强系统一体化统筹建设提供参考，旨在形成与国际接轨的高性能导航应用服务。提出了差分与完好性技术体系在今后一阶段内需要进一步深入研究的问题。

The current GNSS differential and integrity technologies and augmentation technologies at home and abroad are introduced and compared, and the objective and performance of augmentation systems are discussed in - depth. The GNSS difference and integrity technology architecture is defined at global basic level, wide area level, local area level and user end level. The studies provide reference for the overall planning and construction of the GNSS augmentation system of China, with the aim of cooperating with other augmentation systems and providing high - performance navigation services. Finally, several problems to be studied in the next stage are raised.
