- Аннотация: The tasks of coordinates, velocity and acceleration determination by means of GPS measurements are considered in the airborne gravimetry’s applications. The developed algorithms give the following opportunites: • The determination of position using carrier phase observables; • The independent determination of velocity and acceleration using differential Doppler and carrier phase observables. The peculiarities the obtained algorithms for data processing consist of • Dual, single ( L1 and L2) frequency and ionosphere-free carrier phases solutions are used for mutual cross checking. • Doppler solutions are used as initial approximations for corresponding carrier phase solutions. • Simultaneous processing of measurements from several Base stations and/or on-board GPS receivers. The developed methods have been implemented in the software, which is successfully used in commercial surveys for data processing of gravimeter systems GT-1A and GRAVITON-M.
