Abstract
A new approach to the analysis of absolute gravimeter operation propos es that the measured value of gravity should be found as a mean-weight ed value of the acceleration of a free-moving body averaged within eve ry measurement. The weighting functions of absolute gravimeters are de termined. They depend on the gravimeter model used and the allocation of chosen data points within a single measurement. The effective measu rement heights of absolute gravimeters can thus be found and the corre ctions due to linear gravity gradient and finite speed of light establ ished. The results presented cover both direct free-fall and symmetric rise-and-fall types of apparatus.
