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.
