[Hybrid Navigation System Part 4: Integration] Integrating PX4 and External INS Odometry via ROS 2 and Communication Verification
Bymaponarooo 2026년 04월 24일2026년 04월 24일

Hello! To all the graduate students and researchers fighting on the front lines of autonomous unmanned aerial vehicle (UAV) systems, welcome back to the QUAD Drone Lab. In our previous post, <Part 3>, we explored the mathematical limitations of low-cost sensors in completely GNSS-Denied environments—specifically the dreaded ‘drift’ caused by double integration. To overcome this,…
