Analysis of gravimetric observations made by SCINTREX CG-5
Santrauka
From the common adjustment of all observations the standard deviation of a single observation equal to 4 μGal was received, and the standard deviations of adjusted gravity acceleration values about 2 μGal were obtained. Estimation of accuracy using differences from the repeated gravity observations gave a standard deviation of the gravity acceleration values equal to 7.1 μGal. The differences between the gravity acceleration values of first order network adjustment and those, which were received from the adjustment of the gravity observations in 2007, do not exceed 19 μGal, so in some points are higher than declared (10 μGal). It is mean, that further studies of the quality of the Lithuanian National Gravimetric Network are required.
