Multi-Channel Target Shadow Detection in GPS FSR

The paper offers new application of a Multi-channel Forward Scatter Radar (MFSR), which uses GPS signals for detection of air targets on their GPS radio shadows. The multi-channel GPS MFSR detector consists of several channels, which process information from several satellites simultaneously. The phenomena of diffraction in the near area is...

On Evaluating Floating Car Data Quality for Knowledge Discovery

Floating car data (FCD) denotes the type of data (location, speed, and destination) produced and broadcasted periodically by running vehicles. Increasingly, intelligent transportation systems take advantage of such data for prediction purposes as input to road and transit control and to discover useful mobility patterns with applications to...

Precipitable water vapour estimation using GPS in Uganda: Measuring and modelling the precipitable water vapour using single and dual frequency GPS receivers

Additional thesis - Precipitation and especially rainfall are very important for the world’s population. It has its positive and negative side like providing water and contrary causing floods. Therefore it is of utmost importance to make clear and accurate weather predictions. The revolution of GPS in the last few decades gave a new opportunity...

Reductie van multi path-effecten bij GPS met de residuen tabelmethode

In het Global Positioning System (GPS) wordt de positie berekend door de afstanden tot satellieten te bepalen uit de vertragingstijd van de uitgezonden signalen.<br/> Er kunnen echter grote fouten in de positiebepaling ontstaan wanneer de signalen niet alleen rechtstreeks worden ontvangen, maar ook gereflecteerd (multipath). Om dit ...
