The Use of Gravimetric Measurements to Determine the Orthometric Height of the Benchmark in the Port of Gdynia
Abstract
This paper contains a description of the technology used to make gravimetric measurements of the height of a reference point located in the Port of Gdynia, Poland. Measurements were made using a CG-5 gravimeter manufactured by LaCoste & Romberg Scintrex Inc., and determinations of position used a Leica Viva GS15 receiver integrated with a network of HxGN SmartNet GNSS reference stations. The measuring methodology required gravimeter readings to be taken at an absolute measurement station in the Polish official gravimetric network and at new stations. The adopted profile method entailed making a two of measurements at all stations. The measurements relate to terrain with a relatively small height difference between the starting point and end point. It is standard in such cases to assume that gravitation varies linearly with height. This assumption is better satisfied when the gravimetric series is shorter and there is less height variation within it.
