Navmar Applied Sciences Corp. (NASC) and UAV Turbines Inc. (UAVT) have announced plans for a joint flight demonstration of NASC’s TigerShark aircraft with a UAVT micro-turboprop propulsion system. First flights are scheduled before the end of the year. This will mark the first time that a Group 3 UAV (medium endurance and size) is powered by a micro-turboprop engine with... read more

New developments in UAV navigation and control

April 19, 2017By
Modified UAV with actuators enabling rotor tilt.

Since we’re running essentially a navigation magazine, someone had the bright idea that maybe we could bring together the monthly review of UAS/UAV activities combined with some hint of navigation content. Seems reasonable. So delving into the academic world once more, we’ve been searching for prior papers that address novel ways for divining where a UAV might be and how it... read more

Expert Opinions: Trending technologies for UAV navigation

April 19, 2017By

Q: Where is leading technology trending for UAV navigation in complex, unstructured, and uncertain (GNSS-denied) environments in industrial applications? A: Tight integration between GNSS and inertial navigation systems (INS) can provide accurate, reliable navigation in GNSS-challenged environments, and advances in MEMS inertial technology continue to push the performance of systems that meet the size, weight and power requirements for UAV... read more
