Weakening the Flicker Noise in GPS Vertical Coordinate Time Series Using Hybrid Approaches

Assessment of noise in GPS coordinate time series: Methodology and results

[1] We propose a methodology to assess the noise characteristics in time series of position estimates for permanent Global Positioning System (GPS) stations. Least squares variance component estimation (LS-VCE) is adopted to cope with any type of noise in the data. LS-VCE inherently provides the precision of (co)variance estimators. One can also apply statistical hypothesis testing in conjuncti...

Mining Association Rules From Time Series Data Using Hybrid Approaches

Due to the frequent appearance of time series data in various fields, it has always been an essential and interesting research field. A time series analysis involves the methods for analyzing time series data, in order to mine meaningful and other relevant characteristics of the data. In most cases, time series data are quantitative values, so to come up with an intellectually appealing data mi...

Network-based estimation of time-dependent noise in GPS position time series

Some estimates ofGPSvelocity uncertainties are very low, <0.1 mm/year with 10 years of data. Yet, residual velocities relative to rigid plate models in nominally stable plate interiors can be an order of magnitude larger. This discrepancy could be caused by underestimating low-frequency time-dependent noise in position time series, such as random walk. We show that traditional estimators, based...
