Abstract

The paper studies the possibility of using a well-known inertial geodetic method for determining a gravity field anomaly parameter, namely, vertical deflection (VD), in high latitudes. The proposed problem solution includes designing a specialized integrated system comprising a precision IMU and two-antenna GNSS system with a long antenna baseline. The paper presents the algorithms used to solve the problem, accuracy estimates obtained using simulation modeling in MATLAB (Simulink) and the results of sea trials of the GPS compass designed by Elektropribor.
