Combinaison des mesures GNSS et topométriques dans un réseau d’auscultation

Abstract : The combination of several measurement techniques is a common approach in auscultation and structure surveillance. Thus, it seems interesting to combine tachymetry and GNSS which are widespread and fully understood techniques. Besides, because both methods are very different, they bring different information. In this report we studied several ways to combine measurements and their contribution in terms of precision. Moreover, another common issue with combination of measurements is their relative weighting. The VCE (Variance Component Estimation) is the solution we used in order to solve this problem, and notably the HVCE (Helmert VCE) and the LSVCE (Least-Squares VCE).
