Course description, objectives:

This course will describe the key features of the Global Navigation Satellite System (GNSS) and explain why, how, and under which conditions sub-centimeter positioning is possible, with the goal of interpreting the kinematics of actively deforming regions. We will discuss GNSS orbits and signals, reference frames, and the various strategies to convert ranging data (“GNSS observables”) into positions. We will use the Caribbean context to discuss time series of site positions, in particular at continuously recording GNSS stations, from which site velocities and noise characteristics can be extracted. We will then discuss how the resulting velocities can be used for the kinematic interpretation of regional tectonics and for the study of the earthquake cycle.


Prerequisites recommended: a background in geophysics and tectonics as the MSc level, a basic understanding of the physics of electromagnetic waves, some background in linear algebra.
