ENGINEERING. POLICY. PRACTICE. December 2017/January 2018 unmanned systems inside 27 ground-based-only solution as a primary means for separating the aircraft as the non-certified airborne solution is tested. Flom has also read about Facebook's plans to use drones for Internet connectivity, which would mean putting long endurance UAS up in the air for six months at a time. A ground-based radar solution would be perfect for this, he said, eliminating the need for the aircraft to carry on-board radar that it will only use during take-off and landing. None of this has ever been done before, making it an exciting and challenging time to be part of the industry. But there's still a lot to learn and a lot of work to be done. "I don't think there's one solution that's going to fully enable BVLOS," Flom said. "A ground-based solution might work well for certain areas across the country where there's already an existing infrastructure like the type of radar we're using. But it only has a 60 nautical mile service volume, so there's a limited area where you can use this ground-based radar. If you want to f ly further than that, you can use ground-based initially and then an airborne solution to fill in the gaps." The North Dakota site has also worked with NASA as it develops the UTM technology, and was part of national test- ing that took place over the summer. The testing looked at the functioning of mapping, sensing and radar technology while drones f lew different types of missions. Texas Testing The Texas site has collaborated with NASA to test UTM technol- ogy since 2015, said Jerry Hendrix, LSUASC executive director, beginning with simulations and then moving on to actual flights. Early tests focused on making sure the system sent out proper notifications to pilots about the airspace, such as alerting them when they flew outside their authorized area. They then moved on to more complex tests, including the just-mentioned multi-state tests that involved five other tests sites including North Dakota. Development of NASA's UTM will be completed in four phases, with each Technology Capability Level (TCL) adding more complexity. The tests completed over the summer were part of TCL2. The three-week campaign in June focused on f lying small drones BVLOS over sparsely populated areas. LSUASC com- pleted several successful f lights, one of which involved three UAS f lying together over a simulated capsized boat in the Laguna Madre. The AirRobot AR 180 f lew the MESA-DAA airborne sense-and-avoid radar from Echodyne. This radar is designed to enable BVLOS f lights. • ITAR free • Small size, low weight, power and cost • Insensitive to magnetic fi elds • Low gyro bias instability (0.3°/h) • Low gyro noise (0.15°/√h) • Low accelerometer bias instability (0.05 mg) • Excellent performance under vibration and shock • Fully calibrated and customer confi gur able to the specifi c application • 3 inclinometers for accurate leveling • Weight 55 grams, volume <, power 1.5 W STIM300 is fi eld proven in Military Land navigators, Missile systems, Target acquisition systems, Airborne surveillance, DIRCM, Remote Weapon Systems, Launch vehicles and Satellites.
