THE BALLISTIC ABSOLUTE GRAVIMETER ZZG2

Zbigniew Zabek, Waldemar Kielek, Tadeusz Knap

Abstract

The construction and measurement method of transportable absolute Earth’s gravity meter having the relative accuracy of the order of 10-9 is given. The instrument is composed of few separate units. The construction of mechanical and optical units is described in brief only. The construction of electronic units, an measurement method used in the instrument, and original algorithm developed by Z. Zabek and T. Knap to obtain the result of absolute value of local earth gravity acceleration with top actually achievable accuracy are described more in detail.

Keywords
