- Аннотация: An approach to estimating components of the disturbing potential from airborne observations at repeated lines is presented. The use of a strapdown airborne gravimeter is assumed. The proposed approach is based on the error equations of gravimeter’s inertial measurement unit and observation equations based on GNSS. A model of the disturbing potential components is constructed using the cubic splines parameterized by the distance along the flight path. The unknown coefficients at the splines are included in the system’s state vector and estimated by the Kalman filter. Numerical results from simulated data processing were obtained.
