Mar 11, 2020   Space Geodesy, its properties and tools, presented by Mike Pearlman of the Harvard-Smithsonian Center for Astrophysics

Geodesy is the science of accurately measuring and understanding three fundamental properties of the Earth: its geometric shape, its orientation in space, and its gravity field— as well as the changes of these properties with time.
Space Geodesy uses sources external to the Earth: artificial satellites (in satellite geodesy), quasars (in very-long-baseline interferometry, VLBI), and the retroreflectors on the Moon (in lunar laser ranging) to measure these static and time varying properties.
Of current interest are measurements to monitor geodetic parameters and their temporal variations in a global reference frame with a target relative accuracy of 10E-9 – 10E-10, for both scientific understanding of the Earth system and understanding their potential impact on society
Fundamental to these measurements is a reference frame that provides stability over space, time, and evolving technology.
