Mining-induced ground subsidence is a commonly observed geo-hazard that leads to loss of life, property damage, and economic disruption. Monitoring subsidence over time is essential for predicting related geo-risks and mitigating future disasters. Machine-learning algorithms have been applied to develop predictive models to quantify future ground s...

The geological disasters caused by the ground deformation of the goaf have brought huge security risks to the ecological environment and society. Therefore, it is imminent to realize the effective monitoring and stability analysis of the ground deformation of the goaf. In this paper, taking the goaf of the gypsum mine in Diaodao District, Jingmen C...

To maintain safe and smooth operation of urban infrastructures, security evaluation and deformation monitoring have formed a challenging issue, especially for large scale buildings and structures since they are usually built within urban areas and densely populated districts. In recent years, related specific methods have been presented to achieve ...

Over the past years, the International GNSS Service (IGS) has been putting efforts into extending its service by setting up and running the Multi-GNSS experiment and pilot project (MGEX). Several MGEX analysis centers (ACs) contribute by providing solutions containing not only GPS and GLONASS but also Galileo, BeiDou, and QZSS. As the current IGS c...

This research aims to explore policy venues to encourage the use of data from Continuously Operating Reference Stations (CORS) at a national level or National CORS (NCORS). Thailand, among many countries, has established NCORS to observe and process the Global Navigation Satellite System (GNSS) signals to improve the accuracy of positional data tha...

Coordinated universal time (UTC) is the international reference for time and frequency measurement, and the basis of civil timekeeping world-wide. The reception of signals from global navigation satellite systems (GNSS) as a source of time and frequency (synchronization and syntonization) has found widespread use in virtually all user sectors, incl...

How to estimate a strain-rate field from spatially discrete geodetic data has been a longstanding issue. In this paper, a method based on basis function expansion with Akaike's Bayesian information criterion (ABIC) is introduced, by which strain-rate fields can be obtained objectively and stably. By applying the method to GNSS data in Japan, strain...

When the global navigation satellite system (GNSS) is used for positioning in harsh environments with high occlusion and strong reflection, the signals are easily reflected, diffracted, or even blocked, which can lead to multipath and non-line-of-sight (NLOS) errors. Existing stochastic models do not fully consider the significant unmodeled errors,...
