Heliostat UAV Calibration

This technology uses Unmanned Aerial Vehicles (UAVs) fitted with a camera to calibrate heliostats in large Concentrating Solar Power (CSP) or Concentrating Solar Thermal (CST) tower systems. The UAV does not have a single fixed position and provides several advantages over traditional methods using a fixed light source and fixed camera.

STERG's research shows that heliostats calibrated with UAVs track the sun more accurately than heliostats calibrated using traditional methods. In addition, the use of multiple UAVs enables faster and more frequent heliostat calibration.
