GNSS精密数据处理关键技术和方法研究

Research on Key Technologies and Methods of GNSS Precise Data Processing

全球卫星导航系统(GNSS)是所有在轨工作卫星导航定位系统的总称,包括GPS、GLONASS、Galileo、北斗在内的全球星座、区域星座及相关的星基增强系统。本文介绍了GNSS精密数据处理的关键技术及相关方法,阐述了一些基本的数据处理模型,并对GNSS数据精密处理模型进行了阐述,最后对GNSS未来发展趋势进行了展望。

Global Navigation Satellite System （GNSS） is the general term of all the on-orbit satellite navigation and positioning systems, including GPS, GLONASS, Galileo, global constellation including Beidou, regional constellation and the related satellite based augmentation system. This paper introduces the key technologies and methods of GNSS precise data processing, presents some basic data processing models, introduces the GNSS precise data processing model, and finally prospects the future development trend of GNSS.
