A no-nonsense comparison of ArduPilot and PX4 across 6 dimensions — code architecture, control algorithms, parameter systems, learning curve, community culture, and licensing — plus a scenario-based selection matrix and 3 implementation roadmap cost analyses.

How MIMOmesh wireless ad-hoc networks maintain multi-hop throughput through Spatial-Time Division Multiplexing (STDM) — intelligent scheduling of spatially-isolated links in the same time slot.

A comprehensive framework for MUM-T control systems covering 4 control levels (LOS/NLOS/remote/autonomous), Authority Token Model, 3-tier video streaming with semantic ROI, network-adaptive encoding, multi-observer design, and control software roadmap.

A comprehensive deep-dive into ArduPilot’s MAVLink 2.0 protocol stack — covering code architecture (33 files, 8 vehicle types), message routing (20-entry table), bucket scheduling (10 streams), parameter protocol, mission protocol, MAVLink FTP, serial control, high-latency mode, signing/security, 40+ commands, and 80+ message types.

A step-by-step guide to compiling and flashing PX4 firmware for FMU-v6C (STM32H7) flight controllers — covering environment setup, source code management, default/raptor/neural board configurations, four flashing methods, first power-on calibration, and 6 common troubleshooting FAQs.

A detailed engineering guide to designing the flight control system for a small reusable rocket — covering thrust vector control allocation, small-disturbance linearization for pitch/yaw/roll channels, controller design with stability margin analysis, and 100-run Monte Carlo shooting validation under normally distributed parameter errors.

A University of Macau team transforms a quadrotor into a low-cost, indoor rocket thrust-vector control testbed using a gimbal-mounted carbon fiber cylinder. Published in IEEE Transactions on Aerospace and Electronic Systems, the system achieves centimeter-level trajectory tracking with adaptive backstepping control.

A systematic analysis of the rumored Russian Volna Kupol Garant (VKG) Starlink jamming system. Cross-examining Ukrainian and Russian sources, evaluating technical claims about 8-channel uplink interference, and assessing reliability against Starlink’s known anti-jamming capabilities.

Complete hands-on tutorial for setting up ArduPilot Follow Me mode. Track a moving vehicle from the air using an open-source flight controller, Mission Planner, USB GPS, and telemetry — step by step with all parameters, wiring, and safety tips.

Carnegie Mellon University researchers demonstrate agile quadrotor interception using only 3D direction vectors — no distance measurements needed. Trained with differentiable quadrotor dynamics and APG, the system achieves ~30% improvement over point-mass baselines at speeds up to 10 m/s.
