Anomaly Detection in Gps Data
Modern machine learning techniques provide robust approaches for datadriven modeling and critical information extraction, while human experts hold the advantage of possessing high-level intelligence and domain-specific expertise. We combine the power of the two for anomaly detection in GPS data by integrating them through a visualization and human-computer interaction interface. In this thesis ...
متن کاملInversion of GPS meteorology data
The GPS meteorology (GPS/MET) experiment, led by the Universities Corporation for Atmospheric Research (UCAR), consists of a GPS receiver aboard a low earth orbit (LEO) satellite which was launched on 3 April 1995. During a radio occultation the LEO satellite rises or sets relative to one of the 24 GPS satellites at the Earth's horizon. Thereby the atmospheric layers are successively sounded by...
متن کاملData Assimilation with sparse GPs
Inferring wind-fields from remote observations poses two issues that need to be tackled: the first one is to represent two-dimensional Gaussian fields, or processes (for each location we have random variables specifying the X-, and Y-directions. The second problem is the inference with the inherently non-tractable likelihood model, governed by the underlying physics governing the wave formation...
متن کاملDesigning a GPS Tracking Data Collection
During the last decade, GPS tracking has become a key technology for data collection. In this chapter, the authors develop a practice-ready guideline for how to design and conduct GPS tracking investigations. They do so by first developing a V-model for GPS tracking, which describes the different phases of a GPS tracking data collection and the choices that have to be made in each phase. Therea...
متن کاملBackpropagation Processing of GPS Radio Occultation Data
We provide an assessment of the backpropagation (BP) method for processing GPS radio occultations using simulations as well as recent data from CHAMP and SAC-C. It is found that BP gives improved retrievals over the standard Doppler technique, even when multipath ambiguities are not completely removed. In addition, by being an amplitude-weighted algorithm, BP is robust in the presence of receiv...
