Note on The Comparisons of Geodetic Azimuths of The Tunisian Primordial Geodetic Network

Authors: Abdelmajid Ben Hadj Salem

In this paper, we present some comparisons of geodetic azimuths obtained by GPS by classical geodesy and by astronomical observations (Laplace's points). The geodetic azimuths are calculated using 3D coordinates or by plane coordinates (Tunisian Lambert projection). The results obtained confirm that the orientation issued by GPS is identical to astronomical orientation which confirms also the orientation of the Tunisian Primordial Geodetic Network obtained by the definitive adjustment of the French Institut Geographique National in 1984.
