The start-up company Star2Earth, reared in the ESA Business Incubation Centre in the Netherlands, has developed the Oceanpal sensor based on ESA technology that uses navigation satellite signals reflected from a water surface to measure water levels and wave heights. Oceanpal is already operational in Barcelona’s harbour, on Scheveningen pier in the Netherlands and at the LaBaells water reservoir in the Pyrenees. Latest installation is on Lake Laja in Chile where Oceanpal will be used by the Energy company Endesa to plan its electricity production better.
