Abstract
A new free-fall absolute ballistic gravimeter ABG-VNIIM-1 was fabricated at D.I. Mendeleyev Research Institute for Metrology (VNIIM). The gravimeter ABG-VNIIM-1 was tested at the gravimetric site Lomonosov-1 in Lomonosov branch of VNIIM. The estimated total instrumental uncertainty of ABG VNIIM-1 was determined to be 2 × 10−8 m s−2. Typical residuals in the least square evaluation of the trajectory of the test body in a single drop at the site Lomonosov-1 are from 0.3 to 0.8 nm.
