BVLOS long-endurance UAS flights using APX-series IMU and RTX-PP technology: a powerline case study using LiDAR
In the corridor mapping industry, UAS LiDAR survey fills a unique role that is complementary to manned surveys. YellowScan develops all-integrated LiDAR systems for UAS. All units include laser scanner, Applanix INS, embedded computer and batteries. As BVLOS (Beyond Visual Line Of Sight) operation becomes more accepted and common for long endurance UAS flights, the need of a base station for PPK processing limits surveys to its inherent range for the corrections quality. Using Trimble?s new RTX-PP technology, one can create a network of base stations to overcome this issue and fly long endurance flights without having to plan for base station locations, spacing and quality of its data. YellowScan integrates both APX-15 and APX-20 INS in their systems, hence enabling the use of the RTX-PP technology. Based on the use case of powerline inspection, this paper aims at assessing the usability and accuracy of this method compared to the conventional ground control process.
