Knowledge
The student acquires the basic elements of the theory of measure and the physical principles of operation of the instrumentation used in geophysics, with special reference to magnetic, kinematic and gravitational sensors
Will be analyzed in the time-scale construction and operation of satellite tracking point.
Consideration will be given the basics of the description of the Earth's gravitational and magnetic fields and the handling of the gravimetric or magnetometric data.
