摘要
在设置不同观测组数和组内落体数的情况下,分别计算对FG5绝对重力仪的重力观测精度和重力值的影响,并对结果进行了分析。分析结果表明,观测组数设置为13次,每小时1组,组内落体数为100次,能够满足5×10-8ms-2技术指标的绝对重力测定要求。
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 gravi- ty measurement can satisfy the 5.0 × 10^-8ms^-2 accuracy requirement.
