Geodetic Applications of the ROCSAT-3/COSMIC Mission
simultaneous improvement of the GPS satellites’ orbits within a few hours from data collection, essential to all GPS applications (a factor of two improvement can be expected over the current accuracy at 5–10 cm),
improved estimation of the global surface pressure fields, useful for geodynamic and altimetric studies such as Earth rotation, geocenter motion, time-varying gravity, and ocean circulation, and
inclusion of satellite laser ranging reflectors, proposed as a secondary tracking system, will help establish local datum ties to the conventional terrestrial reference frame.
