Possibilities and Limitations of Doppler Positioning in Geodynamics

1979
During the past years Doppler positioning by aid of artificial satellites, especially within the US Navy Navigation System, has been introduced into large fields of geodesy. This new technique nowadays is used to determine control points especially in countries where we have no unique first order triangulations, to combine national geodetic networks ...
