Multi-instrument observations of SCIPS: 1. ISR and GPS TEC results

First simultaneous observations of daytime MSTIDs over North America using GPS-TEC and DEMETER satellite data

Sea level measurements using multi-frequency GPS and GLONASS observations

Global Positioning System (GPS) tide gauges have been realized in different configurations, e.g., with one zenith-looking antenna, using the multipath interference pattern for signal-to-noise ratio (SNR) analysis, or with one zenithand one nadir-looking antenna, analyzing the difference in phase delay, to estimate the sea level height. In this study, for the first time, we use a true Global Nav...

Multivariate Monitoring with GPS Observations and Auxiliary Multi-Sensor Data

In a multi-sensor measurement or monitoring environment, p variables are measured simultaneously. The measured data are correlated and can be monitored to identify special causes of variation in order to establish control and to obtain reference samples to use as a basis in determining the control limits for future observations. One common method of constructing multivariate control charts is b...

Some Observations on Dirac Measure-Preserving Transformations and their Results

Dirac measure is an important measure in many related branches to mathematics. The current paper characterizes measure-preserving transformations between two Dirac measure spaces or a Dirac measure space and a probability measure space. Also, it studies isomorphic Dirac measure spaces, equivalence Dirac measure algebras, and conjugate of Dirac measure spaces. The equivalence classes of a Dirac ...

Tropospheric Delay Corrections to Differential Insar Results from Gps Observations

Differential Interferometric Synthetic Aperture Radar (DInSAR) techniques have been recognised as well-suited for ground deformation monitoring applications. However, the spatially and temporally variable delay of the radar signal propagating through the atmosphere represents a major limitation to accuracy. The dominant factor to be considered is the tropospheric heterogeneity, which can lead t...
