摘要
用于测量垂向重力加速度(g)的A-10绝对重力仪具有高精度、高一致性、便捷式和现场易测等优点。通过野外观测得出:在满足精度的前提下,A-10绝对重力仪的测量组数、下落次数及测量时间可以少于目前FG5绝对重力仪观测相应的采集参数设置;测量结果与精度受观测台质量、天气等外界因素不同程度的影响。
The A-10 absolute gravimeter is a high precision, high coherence, transportable and easy operating instrument in site to measure the vertical acceleration of gravity （g）. Through a long time of field observations, we have recognized that the measurement number of sets, the number of drops and the measurement time of A-10 absolute gravity gravimeter can be less than that of absolute gravimeter FG5 observations of the acquisition parameters set in the condition of meeting the accuracy demand. The results and accuracy can be affected by the observatory quality, weather and other external factors in different extent.
