| Abstract: | There is some height-anomaly between the GPS geodetic height and normal height.In Shenzhen,gravity measurements were more densely taken to establish a mathematical model of quasi-geoid with high resolution and high accuracy to deduce the exact height anomaly.A brief account is given of the requirements for the more densely distributed gravity measurements,and of the basic operations and steps.An evaluation is made of the quality and accuracy of such measurements. |
