<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>A gravity base station is a point on Earth's surface where the absolute value of gravity is well known. Gravity base stations are established to tie relative gravity measurements to an accepted gravity value that has been determined through the use of an absolute gravimeter, or repeated relative measurements to another established base station. They are sometimes also used to measure changes in Earth's gravity over time. Scientists can use repeated measurements at established gravity base stations during the course of a relative gravity survey to determine, account for, and remove instrument drift from relative gravity measurements. </SPAN></P></DIV></DIV></DIV> |
