Concepts of geodetic positioning using GPS/GNSS. Introduction to GNSS other than GPS, including GLONASS, BeiDou and Galileo. Satellite orbit representation, analysis of GPS/GNSS carrier phase measurement errors, differential GNSS, integer ambiguity resolution, static baseline survey and control network design, adjustments of baseline measurements within control networks, height determination using GPS/GNSS, standards and specifications for GPS/GNSS geodetic control, Precise Point Positioning (PPP), online GPS data processing, continuous operating reference stations (CORS). Field exercises to complement the lectures, tutorials and class discussions for a greater understanding of precise GPS/GNSS positioning principles and performance using state-of-the-art user equipment. Discussion of modern geodesy: geometric techniques such as VLBI, SLR, DORIS & GNSS; gravity field mapping & mass transport; geodetic services and applications; the IAG and the Global Geodetic Observing System.
