| In the late 90's, space-based geodetic
techniques such as the Global Positioning System (GPS) reached a level where
millimeter-level positioning became achievable globally. In geophysics, GPS
measurements have been widely used over the past decade to monitor crustal
displacements, with precision levels on the order of 2-3 mm/yr (horizontally)
now routinely achieved.
High precision GPS geodesy and its applications to geophysics will give students a fundamental understanding of error sources and issues relevant to multiple fields, such as surveying, navigation, transportation, GIS, as well as geophysics.
This course will give an overview of the major space geodetic techniques (VLBI, SLR, GPS) and focus on the theory and practice of GPS. A good follow-up course is Kinematics of lithospheric deformation.
The labs will provide hands-on experience in field and data processing techniques, including programming a simple GPS data processing software and learning to use a high-end research software (GAMIT). Knowledge of Matlab and Unix/Linux is not required but will help.
