Tidal forces and the estimation of the relative scale factor for CG-5 gravimeters

Publisher

Location

Greater Copenhagen area

Two relative gravimeters CG-5 were placed next to each other in the basement of DTU building 328 and measured gravity acceleration simultaneously during a 28 day period with the output frequency of 1 averaged reading pr. minute. Each output reading is an average of 55 single gravimeter measurements. The tidal forces (the gravitational acceleration from Sun and the Moon) can be regarded as being the same for both gravimeters. The two gravimeters have individual instrumental drift (which can be modeled by a linear function). The deviation of the reading from the linear drift function is the effect of tidal accelerations. A comparison of these two gravimeters can be used to determine the relative scale factor between them.

Technical University of Denmark

For almost two centuries DTU, Technical University of Denmark, has been dedicated to fulfilling the vision of H.C. Ørsted – the father of electromagnetism – who founded the university in 1829 to develop and create value using the natural sciences and the technical sciences to benefit society.


Today, DTU is ranked as one of the foremost technical universities in Europe, continues to set new records in the number of publications, and persistently increases and develops our partnerships with industry, and assignments accomplished by DTU’s public sector consultancy.
