Choosing the right transmit power for a wireless link is about system balance, not maximum watts. This engineering guide breaks down link budgets, antenna height, terrain blockage, bandwidth, terminal form factors, battery life, thermal limits, EMC, and regulatory constraints across five platform types.
Meet HackRF One: the open-source, half-duplex SDR transceiver covering 1 MHz to 6 GHz with 20 MHz bandwidth. Learn to capture FM, ADS-B, NOAA weather satellites, and more — with hardware schematics, firmware, and tools all fully open under GPL-2.0.
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.
