A new application using The Global Navigation Satellite System is the main objective of a project developed at the Department of Advanced Geodesy of CTU in Prague. Essential functionality is determining the location of a moving object on a predefined track. New and unique features deal with simultaneously processing GPS measurement data with other information, such as information about trajectory and object velocity. This method reduces the minimum number of satellites necessary to locate a moving object to only two satellites. The fully developed system may be useful for active management and tracking of public city transportation or monitoring of freight movement, e.g. hazardous materials.Głównym celem projektu realizowanego w Katedrze Za...
