Application of an improved clustering approach on GPS height time series at CMONOC stations in Southwestern China
Autor: Shuguang Wu, Zhao Li, Houpu Li, Guigen Nie, Jingnan Liu, Yuefan He
Publikováno v: Earth, Planets and Space, Vol 73, Iss 1, Pp 1-15 (2021)
Abstract The hydrological, geological and meteorological conditions in southwestern China are relatively complex, so that the land surface deformation presents various features. Using 58 Crustal Movement Observation Network of China (CMONOC) stations

Sequential Ambiguity Resolution Method for Poorly-Observed GNSS Data
Autor: Haiyang Li, Guigen Nie, Shuguang Wu, Yuefan He
Publikováno v: Remote Sensing, Vol 13, Iss 11, p 2106 (2021)
Integer ambiguity resolution is required to obtain precise coordinates for the global navigation satellite system (GNSS). Poorly observed data cause unfixed integer ambiguity and reduce the coordinate accuracy. Previous studies mostly used denoise fi

Analysis and Discussion on the Optimal Noise Model of Global GNSS Long-Term Coordinate Series Considering Hydrological Loading
Autor: Yuefan He, Guigen Nie, Shuguang Wu, Haiyang Li
Publikováno v: Remote Sensing, Vol 13, Iss 3, p 431 (2021)
The displacement of Global Navigation Satellite System (GNSS) station contains the information of surface elastic deformation caused by the variation of land water reserves. This paper selects the long-term coordinate series data of 671 International

Comparative Analysis of the Effect of the Loading Series from GFZ and EOST on Long-Term GPS Height Time Series
Autor: Shuguang Wu, Guigen Nie, Xiaolin Meng, Jingnan Liu, Yuefan He, Changhu Xue, Haiyang Li
Publikováno v: Remote Sensing, Vol 12, Iss 17, p 2822 (2020)
In order to investigate the effect of different loading models on the nonlinear variations in Global Positioning System (GPS) height time series, the characteristics of annual signals (amplitude and phase) of GPS time series, loading series from Deut

A novel partial ambiguity method for multi-GNSS real-time kinematic positioning
Autor: Shuguang Wu, Haiyang Li, Yuefan He, Jing Wang, Guigen Nie
Publikováno v: Journal of Navigation. 75:540-553
Recent progress in using real-time kinematic (RTK) positioning has motivated the exploration of its application due to its high accuracy and efficiency. However, poorly-observed satellite data will cause unfixed ambiguities and markedly biased soluti

Comparative Analysis of The Correction Effect of Different Environmental Loading Products On Global GNSS Coordinate Time Series
Autor: Shuguang Wu, Yuefan He, Guigen Nie, Haiyang Li
The global navigation satellite system (GNSS) coordinate time series is affected by the environmental loading (including atmospheric loading (ATML), hydrological loading (HYDL), non-tidal oceanic loading (NTOL), etc.) and many organizations now provi

Application of an annual phase-augmented clustering approach to annual detection of vertical GPS station deformation
Autor: Shuguang Wu, Jingnan Liu, Haiyang Li, Xiaolin Meng, Changhu Xue, Guigen Nie, Yuefan He
Publikováno v: GPS Solutions. 25
We present an improved clustering approach for grouping regional GPS stations with similar annual signals into four similarity levels. A newly introduced criterion, the annual phase difference among stations, reinforces the clustering process and res
