Integrated scientific and societal user requirements and functional specifications for the GGOS,netary spacecraft tracking and navigation. Providing an accurate, stable, homogeneous, and maintainable terrestrial reference frame, celestial reference frame, and the Earth rotation parameters linking them together is one of the essential goals of GGOS.

善辩

Towards GGOS in 2020,. In doing so, GGOS provides the observational basis to, e.g., determine mass transport in the Earth system and thus serves the Earth science community with Earth observations and geodetic products relevant for many studies. The accuracy of, and the consistency between, all GGOS products shall be at the 10. level or better.
