Abstract
The methods for obtaining a priori and a posteriori estimates of the accuracy of the global Earth’s gravity field (EGF) models in terms of geopotential spherical harmonics are considered and classified. The ways of how to accomplish this task, taking into consideration the latest advances in the creation of EGF models, are discussed. The main requirements to the database and software used to estimate the gravity field error model are formulated.
