Abstract
Efficiency of using global navigation satellite system (GNSS) measurements for determining the gravity anomalies (GA) at sea by solving the filtering and smoothing problems based on satellite and gravimeter data is studied. The GA, ship heaving, errors of satellite and gravimeter measurements are presented as stochastic processes. The analysis is based on the standard deviations of the GA estimation errors, calculated at different heaving and in different modes of GNSS data processing.
