Reference satellite selection method for GNSS high-precision relative positioning

Model Reference Control for Ultra - High Precision Positioning Systems

MODEL REFERENCE CONTROL FOR ULTRA-HIGH PRECISION POSITIONING SYSTEMS by Lan Yu Due to the increasing demands of high-density semiconductors, molecular biology, optoelectronics, and MEMS/NEMS in the past decades, control of ultra-high precision positioning using piezoelectricity has become an important area because of its high displacement resolution, wide bandwidth, low power consumption, and p...

Improved atmospheric modelling for large scale high-precision positioning based on GNSS CORS networks in Australia

This contribution describes a recent Australian Research Council (ARC) project funded under the ARC-Linkage Scheme. The research team comprises researchers from RMIT University, UNSW, University of Melbourne, Spatial Information Infrastructure and the Department of Lands, NSW. The aim of the project is to enhance the utility of continuously operating reference station (CORS) networks in the sta...

Compact Integration of a GSM-19 Magnetic Sensor with High-Precision Positioning using VRS GNSS Technology

Magnetic data consists of a sequence of collected points with spatial coordinates and magnetic information. The spatial location of these points needs to be as exact as possible in order to develop a precise interpretation of magnetic anomalies. GPS is a valuable tool for accomplishing this objective, especially if the RTK approach is used. In this paper the VRS (Virtual Reference Station) tech...

Achievable Positioning Accuracies in a Network of GNSS Reference Stations

A Recursive Quasi-optimal Fast Satellite Selection Method for GNSS Receivers

Marc-Antoine Fortin is currently pursuing his Ph.D. in the field of GNSS receivers’ robustness at École de technologie supérieure (ÉTS) in Montréal, Canada. He previously received an Electrical Engineering Master’s degree from École Polytechnique de Montréal (Canada) in 2005 and a Bachelor’s degree in the same field from Université de Sherbrooke in 2003 (Canada). He is interested in new methods...
