Space-Based Geodesy
Space-Based Geodesy : Space-based technologies to measure the positions of geodetic monuments on the Earth. A fundamental departure from the traditional geodesy is its reference to an inertial reference frame rather than those fixed to the Earth. Current accuracy of better than a centimeter for sites thousands of kilometers apart are good enough for measuring the present-day plate motion. See Stein and Klosko (2002), and Feigl (2002)
