对应用于重力测量领域的计量测量标准定义的分析表明，重力网络和绝对弹道重力仪都可以作为重力测量中的测量标准，即自由落体加速度测量中的加速度单位的标准。目前，绝对弹道法被公认为是测量自由落体加速度的主要参考方法。弹道重力仪作为加速度这一衍生物理量的测量标准，应溯源到长度和时间（频率）单位的测量标准。绝对弹道重力计的准确度水平可以通过比较在多个重力计可以根据指定的技术协议同时进行测量的地点组织的测量结果来确定。
The analysis of the definition of a measurement standard in metrology applied to the field of gravimetry shows that both gravity networks and absolute ballistic gravimeters can be the measurement standards in gravimetry, i.e., the standards of the acceleration unit in the measurement of free-fall acceleration. Currently, the absolute ballistic method is recognized as the primary reference method for the measurement of free-fall acceleration. As the measurement standard of acceleration, a derived physical quantity, the ballistic gravimeter should be traceable to the measurement standards of length and time (frequency) units. The accuracy level of absolute ballistic gravimeters may be determined by comparing the results of their measurements organized at sites where several gravimeters can perform measurements simultaneously according to a specified technical protocol.
