... Moreover, because of the complexity of space technology, gathering geodetic data is no longer a simple matter of a field party making measurements and an individual serving as "computer" for the network adjustments. Instead, there is a huge variety of tasks to be done, including maintaining continuity over decades of observational techniques, monumentation, network maintenance, education, and survey practice, together with ancillary services such as technology development, data management, orbit determination, and field coordination.

... The U.S. government should sponsor, as a critical national priority, a vigorous coordinated program for the development and exploration of modern geodetic techniques' through aggressive pursuit of continued technological advances and through a long-term commitment to the routine acquisition' reduction archiving, and distribution of global and regional high-precision geodetic data.

... Global geodetic networks, with fiducial stations sited on extremely stable monuments located in stable plate interiors, should be regularly observed as calibration points for transient deformation at plate boundaries. For example, the "Fiducial Laboratories for an International Natural Science Network" (FLINN)

... Error analysis studies suggest that resolution of the global gravity field to 100 km can be obtained by the use of satellite-borne gravity "radiometers, one of which is currently planned for the European ARISTOTELES mission, to fly at 200 km, with an accuracy goal of 5 mgal. Enhanced resolution can be obtained by flying a superconducting gravity "radiometer in a drag-free configuration at an altitude of 160 km, for a planned accuracy of 1-mgal.

... These data would also support establishment and maintenance of conventional terrestrial coordinate system, which is necessary for comparison of results obtained by different space geodetic technologies, including very long baseline interferometry, satellite and lunar laser ranging, and the Global Positioning System.
