Fundamentals of geopotential theory - Laplace's and Poisson's differential equations, spherical harmonic analysis, elementary boundary-value problems. Gravity field modelling - Stokes's determination of the geoid, normal gravity field, deflections of the vertical, dynamic satellite geodesy, least-squares collocation. Anomalous gravity field - disturbing potential, gravity anomalies. The measurement and rigorous reduction of gravity data to datum. Effect of the gravity field on surveying measurements - orthometric corrections to spirit levelling, deflection corrections to survey observations, use of the geoid in survey reductions. Relativistic effects in geodesy. Earth rotation and orientation - precession, nutation, motion of the geocentre, length of day. Dynamic properties of the Earth - solid-Earth tides, elementary plate tectonics, postglacial rebound. Use of the gravity field in inertial surveying systems.
