Most of NGS' gravity base station descriptors have been digitized and can be
accessed in pdf format
from the
Gravity Base Station list on record with
The Pan-American Center Earth and Environmental Studies (PACES), Gravity and Magnetics Research Division.
Note:
The gravity values published with PACES are subject to updating at any time,
without necessarily being updated on NGS descriptions.
Notice of any required revisions to NGS descriptions are welcomed.
