Don’t be fooled by flashy IMU datasheets. The 6 metrics that truly matter: noise density (μg/√Hz), bias stability (°/hr), temperature drift (°/s/℃), range, bandwidth (≥1kHz), and post-shock bias change. Includes field-tested thresholds, 3 real failure cases (¥800,000 loss), and a printable selection checklist for industrial drone flight controllers.
How to track infrared drones at just 3-10 pixels where AI fails completely. Multi-frame energy accumulation + motion trajectory modeling: traditional IR detection as safety net, Track-Before-Detect (TBD) for weak targets, Kalman/particle motion trackers, and a staged 3-tier strategy (<10px / 10-30px / >30px) for counter-drone systems.
QuadRF is an open-source 4×4 MIMO SDR module that gives everyone ‘electromagnetic X-ray vision’—visualizing WiFi through walls, tracking DJI Mini drones via 5GHz control signals, and AR overlays of the RF world. $499 plug-and-play kit with preloaded SD card, plus EME moon-bounce and phased-array research applications.
