Neptune consists of two products. The first is EOLOS, a type of buoy using light-radar (LiDAR) distance measurement. It can measure wind speeds at heights of more than 200 metres above the sea surface, giving it a competitive advantage over masts. The other is NEPTool, a highly accurate forecasting programme that can simulate wind, wave and sea currents. Thisis an improvement over existing commercial systems for measuring winds,sea waves and sea currents. Neptune solves the problem of installing expensive masts in offshore wind farms.
