摘　　要：我国学者不久前进行了利用重力固体潮观测资料验证广义相对论关于引力速度等于光速的研究.汤克云研究员的论文认为,重力固体潮观测资料验证了引力速度等于光速;而黄超光研究员的论文则认为,汤克云论文的重力固体潮观测分析与引力速度无关.本文认为,由于时间测量精度比重力测量精度要高得多,所以进行这项研究,走时间测量的技术路线应该比走重力测量的技术路线更为现实,从而提出了基于地球引力的"GPS卫星实验方案".Recently some scholars in our country made use of gravity tidal observation data to validate the theory of general relativity about the gravitational velocity equals the speed of light.The research paper of professor Tangkeyun indicates that the tidal gravity observation data verify the gravitational velocity equals the speed of light;however,the research paper of professor Huangchaoguang shows that Tang＇s analysis of the tidal gravity observation data has nothing to do with the speed of gravity.This paper argues that the time measurement precision is much higher than gravity,hence,it is more realistic to validate the gravity speed in time measurement;and proposes the＂GPS satellite experiment scheme＂based on the gravity of the Earth.
