The UFACET systems seeks to fly a UAV drone along a trajectory that systematically scans a heliostat field. Flight approach angles and paths are chosen to view each assessed heliostat through a range of positions so that heliostats in front of the heliostat are seen in reflection sweeping from the top to the bottom of the assessed heliostat. Given a heliostat field description, calendar date and time of year, the UFACET Flight Planner computes this trajectory and outputs a flight-ready flight plan.
