DeviceGuru writes: Raytheon is switching its UAV control system from Solaris to Linux for U.S. military drones, starting with a Northrop Grumman MQ-8C Fire Scout helicopter. Earlier this month Raytheon entered into a $15.8 million contract with the U.S. Navy to upgrade Raytheon’s control systems for unmanned aerial vehicles (UAVs), according to a May 2 Avionics Intelligence report. The overhaul is designed to implement more modern controls to help ground-based personnel control UAVs. Raytheon’s tuxified version of its Vertical Takeoff and Landing Unmanned Air Vehicle (VTUAV) Tactical Control System (TCS) will also implement universal UAV control qualities. As a result the TCS can be used in in all U.S. Navy, Air Force, Army, and Marine Corps UAVs that weigh at least 20 pounds. By providing an open standard, the common Linux-based platform is expected to reduce costs by limiting the types of UAV control systems that need to be built and maintained for each craft.
