SATELLITE NAVIGATION. RAW DATA PROCESSING FOR GEOPHYSICAL APPLICATIONS

摘要

Satellite navigation systems are widely used in geophysical applications for precise trajectory determination of a vehicle-carrier of geophysical equipment. In particular, in airborne gravimetry it is necessary to determine the velocity and acceleration of the vehicle in addition to the position determination. Mathematical models and algorithms for the solution of these problems are described. The source data consists of differential Doppler and carrier phase GPS observations.
