The goal of this course is to introduce the ideas of the World Positioning System and to display its utility to numerous elements of Earth Sciences. The particular content material of the course relies upon every year on the pursuits of the scholars within the class. In some circumstances, the category pursuits are in direction of the geophysical functions of GPS and we focus on excessive precision (millimeter stage) positioning on regional and world scales. In different circumstances, the pursuits have been extra towards engineering functions of kinematic positioning with GPS through which case the focus is on positioning with barely much less accuracy however having the ability to take action for a shifting object. In all circumstances, we focus on the elemental points in order that college students ought to acquire an understanding of the fundamental limitations of the system and the right way to lengthen its utility to areas not but absolutely explored.
