Nowadays, an accurate gravity network, based on absolute gravity values determined by modern free-fall gravimeters, provides an important reference frame for the quality check and the transformation of historical data to a modern gravity frame.
another aim is to develop a methodology for the determination of seasonal changes in gravity acceleration (mainly on the basis of experimentally verified hydrological influences) and to create a methodology for uniform processing of absolute gravity measurements (including both existing and newly discovered instrument repairs and local influence of the environment).
The above information from the base station were needed, because the used gravimeter cannot determine the absolute gravity, but only the difference in their readings at two stations, which is proportional to the difference between the gravity values at the two stations.
What the public now have a right to know is that this Government accepts the absolute gravity of the crisis that we are facing and spells out clearly for all to see what measures they are going to take to stop us hurtling towards the abyss.
Pic easily alternates between passages of pure play (kids gleefully playing in a paradise of their own making, Katrin enjoying a dancing robot) and absolute gravity (Dieter beating his dog, a drowned unidentified person being retrieved from the lake).
The gravity survey points were connected to the 3rd-order points of the Estonian gravity network where gravity acceleration values with an uncertainty of [+ or -]0.05 mGal are known in the national gravity system GV-EST95, based on the absolute gravity measurements (Ellmann et al 2009; Oja 2012).
