FROM GENERIC TO SYNTHETIC GRAVITY MODELING - A COMPARISON FROM METROLOGIC PERSPECTIVE
Andreas Lindau
Abstract:
Many mechanical quantities in metrology are affected by the local gravity. Modern gravimetric methods allow to determine the local gravity value with sufficient accuracy, but the effort is still time consuming and expensive. An interpolation within available gravity databases mostly does not suffice because of an inadequate data density compared with the heterogeneous field. This study gives a short overview of today’s most important representations of the physical gravity field. The classical methods will be introduced from the perspective of the usability in metrology and compared to some strategies in synthetic gravity modeling.
