GPS installation in the French Alps

I stayed 10 days installing and monitoring GPS stations in the Western French Alps. We were more than 30 scientists distributed in teams of 2 people camping around the mountains. Me and my partner were in the Massif des Ecrins, one of the most beautiful alpine regions hosting several glaciers, and the Massif du Queyras, a lower altitude but one of the few places of the Alps where you still feel isolated.
