%X To estimate the effects of set and drop numbers on FG5 absolute gravity measurement,different set and drop numbers were taken in a test and the result of absolute gravity accuracy and gravity value were calculated and analyzed.The results show that when the sets is 13,1 set/hour and 100 drops/set then the FG5 absolute gravity measurement can satisfy the 5.0×10-8ms-2 accuracy requirement.
