The EstrellaSat driver fatigue system is now monitoring 30 drivers operating 10 trucks at a high-altitude mine in Peru.The same system is being installed in a mine in Botswana. EstrellaSat, now Wombatt, was supported during start-up by ESA’s Business Incubation Centre in Noordwijk, the Netherlands. The system incorporates spin-offs from several space technologies to lowerworkplace incidents caused by fatigue of haulage truck and other large machinery operators in open pit mines.
