Journal ArticleDOI
Accuracy and reliability of multi-GNSS real-time precise positioning: GPS, GLONASS, BeiDou, and Galileo
Xingxing Li,Xingxing Li,Maorong Ge,Xiaolei Dai,Xiaolei Dai,Xiaodong Ren,Mathias Fritsche,Jens Wickert,Harald Schuh +8 more
TL;DR: In this paper, the authors presented a GPS+GLONASS+BeiDou+Galileo four-system model to fully exploit the observations of all these four navigation satellite systems for real-time precise orbit determination, clock estimation and positioning.
Journal ArticleDOI
Precise positioning with current multi-constellation Global Navigation Satellite Systems: GPS, GLONASS, Galileo and BeiDou
TL;DR: This paper develops a four-system positioning model to make full use of all available observations from different GNSSs to bring about significant improvement of satellite visibility, spatial geometry, dilution of precision, convergence, accuracy, continuity and reliability.
Journal ArticleDOI
Reprocessing of a global GPS network
Peter Steigenberger,Markus Rothacher,Reinhard Dietrich,Mathias Fritsche,Axel Rülke,Sibylle Vey +5 more
TL;DR: In this paper, the authors performed a reprocessing of a global GPS network over the last decade in a joint effort and showed significant improvements in the quality and homogeneity of the estimated parameters and will allow for new geodynamic and geophysical interpretations.
Journal ArticleDOI
Impact of higher‐order ionospheric terms on GPS estimates
Mathias Fritsche,Reinhard Dietrich,Christoph Knöfel,Axel Rülke,Sibylle Vey,Markus Rothacher,Peter Steigenberger +6 more
TL;DR: The modeling of 2nd and 3rd–order ionospheric correction terms is part of the optimized strategy in an ongoing reprocessing project dealing with a global GPS network and spanning the time period from 1994 up to present time.
Journal ArticleDOI
Seasonal Water Storage Variations as Impacted by Water Abstractions: Comparing the Output of a Global Hydrological Model with GRACE and GPS Observations
TL;DR: In this paper, the authors compared both gravity recovery and climate experiment (GRACE) and global positioning system (GPS) observations for the first time, total water storage (TWS) on the land area of the globe as computed by the global water model WaterGAP (Water Global Assessment and Prognosis) was compared to both GPS and GRACE.
