Abstract

At present the ballistic method of measuring the absolute value of gravitational acceleration g is considered to be the most accurate and Promising.1-4 The value ofg is calculated from the results of measuring the travel and time of free-fall of a test mass. The travel is measured using a laser interferometer, with the wavelength of laser radiation stabilized to an atomic reference point in the spectrum of its radiation being the measure of travel. Time intervals are measured in signals of precision, for example, rubidium frequency standard.
