Research on Methods of Determining Level Surfaces of the Earth'S Gravity Field

摘要

Contents: Studies of dispersionmethod to determine terrestrial refraction, the use of the results to obtain geoidal sections by means of vertical angle measurements. Geoidal studies by gravimetrical method, using Rudzki reduced gravity over rugged testareas. Use of satellites to improve the gravimetrical method. Horisontal pendulum studies and secular variation of gravity. (Author)
