Prerequisite(s):	10458 (v.2) Measurement and Adjustment Analysis 381 or any previous version AND 10461 (v.3) Satellite and Space Geodesy 381 or any previous version
Syllabus:	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.
Unit Outcomes:	On completion of this unit students will have - Technological and information literacy skills, effective written and oral communication skills, an improved capacity for critical, creative and analytical thinking, and the ability to work independently andcollaboratively.
