| Abstract: | The FG5 absolute gravimeter was applied to the absolute gravity measurement at the 12 absolute gravity fiducial stations of the Crustal Movement Observation Network of China near the ocean. The Earth tide and ocean loading correction were analyzed in the absolute gravity determination. As a result, the FG5 absolute gravimeter at Shanghai fiducial station precisely detected the coseismic response to Japan Ms6.0 earthquake. The standard deviation of Set Scatter of all stations was proved to be better than 5×10 -8 ms -2. |
| Keywords: | Continental Network Project(CNP) fiducial station FG5 absolute gravimeter observation accuracy co seismic response |
