用东京船上重力仪(T.S.S.G)进行海上重力测量。1962年和1968年友田等对该重力仪的机械结构和资料处理方法已在有关文章中进行了论述。但是,从那以后,两方面均有所改进。本文描述资料处理的方法,特别强调了有限取样时间的二阶校正和弹性动力重力仪的影响。同时,还讨论了水平加速度对东京船上重力仪的影响。这与维宁—曼乃兹海底重力仪、拉科斯特—隆贝格陀螺稳定船上重力仪以及格拉夫—阿斯卡尼亚船上重力仪也有很大关系。
Offshore gravity measurement with T.S.S.G on board. In 1962 and 1968 Tomoda and other mechanical structure of the gravimeter and data processing methods have been discussed in the article. However, both have improved since then. This article describes the approach to data processing, with particular emphasis on the second order correction of finite sampling times and the impact of elastic dynamic gravimeters. At the same time, the influence of horizontal acceleration on Tokyo gravity meter is also discussed. This is also related to the Vignan-Mannitz seabed gravimeter, the LACOST-Lombberg gyro-stabilized gravimeter and the Graf-Ascanian shipboard gravimeter.
