Morzine-Avoriaz: densification d'une infrastructure existante. Le téléphérique des Prodains comme nouvelle porte d'entrée pour la station (F)

François Bianco

Avoriaz (1800 m), station de montagne semble arriver à sa «taille limite», selon Jacques Labro. Imaginée pour que le ski soit roi, les pistes se faufilent entre le bâti qui s'adapte précisément à sa topographie. On ne peut plus augmenter la densité, au ris ...

Calibration of the GNSS Signal Amplitudes in the Interference Pattern Technique for Altimetry

Pierre-André Farine, Cyril Botteron, Miguel Angel Ribot Sanfelix, Mohammed Benjelloun

Global Navigation Satellite Systems signals can be used in bi-static radar systems in order to get altimetric measurements. With a single classic GNSS ground-based receiver processing the combination of the signals coming directly and after one reflection ...
