Some issues of the national gravimetric network development in Lithuania
Santrauka
During the three months of period of investigations the zero drift of the gravimeters was changed from 17 till 197 mu Gal/day. The National gravimetric network was adjusted using software package GRAVSOFT. Total number of observations is 33777. The three absolute gravity stations were chosen as initial points. Standard deviation of the single observation equal to 5 mu Gal, and standard deviation of gravity acceleration of the single points equal to 3 mu Gal were received.
