45 June/July 2019  www.insideunmannedsystems.com  unmanned systems inside sponsored by and Inside Unmanned Systems, featured an expert panel that included Chris Wheeler, business area director integrated technologies OEM at Trimble Inc.; Joseph J. Hutton, MASc, P.Eng, director of inertial technology and airborne products, Applanix; My-Linh Truong, unmanned laser scanning/UAS segment manager, RIEGL USA; and Mike Hogan, business development manager, Microdrones. Poss, CEO of ISR Ideas and a columnist for this magazine, noted that the subject of unmanned systems is "near and dear to my heart." But he added that precision navigation is critical to both aviation and unmanned systems. TECHNOLOGY FEATURES, PRODUCT LINEUP Wheeler kicked off the panelist portion of the webinar by addressing the need to understand GNSS and its benef its, a long w ith the abilit y to separate bet ween nav igation guidance control, payload control, and static versus pass-to- pass accuracy. Regarding the role of precision GNSS, there are two points to think about, he said: guidance navigation and control. "This is about making sure you know your unit is where it's supposed to be, knowing its location and also making sure the controls are able—especially in an autonomous situation—to control the force, the lift, the direction and such," he explained. "Payload control is about the actual unit that you're bringing out, whether it's a camera, a LiDAR, whatever system you have on your UAV. We want to make sure we're adjusting that camera or LiDAR to capture the proper data based on movements and differences in regard to the control." Wheeler touched on the benefits of RTK, including terrestrial corrections, and explained the features of Trimble VRS and RTX solutions, which include: Trimble VRS • RTK-based solution using base station network • Delivered by IP or cellular transmission • Near-instant initialization Trimble RTX • Worldwide solution based on satellite corrections • Correction provided via satellite • Significantly faster convergence via New Trimble Fast Networks When discussing reliability and robustness, Wheeler said, you need to consider GNSS filtering and hardware robustness, frequency support, antenna reliability and size, the RTK engine algorithm and your post-processing solution.
