Abstract

After reviewing the evolution of GPS equipment used by SHOM (Service Hydrographique et Océanographique de la Marine) since 1985, this article describes recent experience from a hydrographic survey off French Guiana, using differential GPS as a unique positioning system. This practical experience facilitates the development of an operation practice for a system which from now on covers most needs of the hydrographer.
