AdaCore’s GNAT Pro cross-development environment has been selected by the Polytechnic University of Madrid (Universidad Politécnica de Madrid / UPM), for the UPMSat-2 UNION satellite project’s real-time on-board and ground control software. The 50kg micro-satellite, scheduled to be launched in Q4 2015, will provide a technology demonstration platform for the university from a sun-synchronous orbit nearly 600 km above Earth.
