In Geodetic Science, we are concerned with the size and shape of the Earth, the realization of terrestrial reference frames, and the estimation of spatial coordinates, Earth orientation parameters, crustal deformation, tides, the mean and time-variable gravity field, and mass fluxes associated with the Earth system. We use a wide range of instruments including GPS, very-long baseline interferometry, radar, InSAR, Lidar, laser and microwave altimetry, optical imaging, inertial sensors, and gravimeters and gravity gradiometers. These devices are deployed in situ, on aircraft and on satellites. They provide fundamental observations for geodetic control and for many branches of the Earth sciences including geophysics, geodynamics, geomorphology, geology, oceanography, hydrology, glaciology, meteorology, space physics and climate change research.
Geodetic science engages a wide range of mathematical applications including boundary values problems, computational geometry, satellite orbital theory, adjustment theory and optimal estimation, signal processing, and the encoding of geoinformation. We expose our students to, and attract students from physics, mathematics, statistics, geophysics, and computer science.
