Go beyond basic log reading. This guide walks through GYRO, PID, and CTUN curve analysis on three real aircraft — F450 DIY build, MARK5 racing drone, and a 3D-printed micro-UAV — to find the exact cause of vibration and oscillation, with actionable fixes for each case.
Learn to diagnose drone crashes with Mission Planner DataFlash logs. Master the five key log types (ATT, CTUN, NTUN, PM, ERR), a 4-step analysis workflow, and common fault signatures — no guessing, just data-driven troubleshooting.

A complete source-level analysis of the PX4 MAVLink module (src/modules/mavlink/): two-thread architecture, multi-instance support, three-layer multiplexing across physical links, protocol services, and stream-based message flow from poll() to uORB publication.
The AERIS-10 open-source active phased array radar delivers electronic beam steering, pulse compression, Doppler processing, and CFAR detection at a fraction of commercial cost. Schematics, PCB layouts, BOM, FPGA firmware, STM32 code, and Python GUI are fully open under CERN-OHL-P and MIT licenses.
KAIST’s IROS 2026 paper introduces a delay-aware multi-drone active triangulation method that estimates an aerial target’s 3D position under real communication latency, sensor noise, and packet loss. Perception-consistent rewards cut RMSE to 0.547 m, reduce trajectory loss by 27%, and lift triangulation success from 32.2% to 78.1%.
DroneBridge for ESP32 turns a $2 chip into a 1 km telemetry link supporting MAVLink, MSP, and LTM protocols. With ESP-NOW long-range mode, AES-GCM 256-bit encryption, and transparent serial passthrough, it replaces $100+ telemetry radios for PX4, ArduPilot, INAV, and Betaflight.
AeroVironment and Applied Intuition integrate Acuity ISR/Strike collaborative autonomy software into the Mayhem 10 UAS. A single operator supervises multi-vehicle swarms that share ISR data, track targets, and dynamically reallocate missions. Recent tests validated synchronized flight, swarm cooperation, and adaptive tasking.
How a $10 USB TV dongle unlocks the entire 24 MHz–1.7 GHz radio spectrum. Hands-on guide for communications engineering students: ADS-B aircraft tracking, NOAA satellite imagery, I/Q sampling explained, antenna selection, and real-world SDR projects.
The Fusion library by x-io Technologies combines gyroscope, accelerometer, and magnetometer data with Madgwick’s revised AHRS algorithm — C and Python ready. Includes acceleration rejection, magnetic anomaly detection, and sensor recovery for reliable real-time attitude estimation.
Build a room-level indoor positioning system with three ESP32 BLE proxy nodes and BPS integration for Home Assistant — track devices, automate multi-floor smart home logic, and locate Bluetooth tags for under $10 total.
