The proposed activity’s main objective is to develop an innovative solution for monitoring the construction processes of large infrastructures by using cutting-edge technologies such as GNSS (global navigation satellite systems), satellite EO (Earth observation), drones and wearable devices to guarantee a safe work environment for the construction workers and avoid delays in the construction schedule.  MALCO will use real-time PNT (Positioning, Navigation, and Timing) information, e.g., speed and high positioning accuracy (< 50cm), for drones’ positioning and tracking workers.
