О стабильности значения силы тяжести Земли

Modern method and equipment allow make the measurement of gravity at 10-9 level from normal value g0 (up to 1 microgal = 10 nm/sec2). We exclude of systematic and periodic effects and after this procedure we must estimate the stability of earth's gravity at time. Space geodesy method (VLBI) can make estimation of the height (Earth radius) at 0.1 mm level. Experimental results were received by absolute laser ballistic gravimeters at our and foreign observatories. These results analyze for stability estimation of earth's gravity for last decades.
