Linux Powered Autonomous Arctic Buoys
summary
Low-cost, COTS Arctic buoys measure albedo, weather, sonar depth and temperature and run a custom embedded Linux stack that actually works at −40°C. The system uses a Technologic Systems ARM board (~$150) with a custom kernel and compiled UVC driver to run a Logitech C920 webcam (~$75), Belkin USB hub, SD-card local archives and occasional Iridium text uplinks (≈ $1.50/min dialup). Video bursts of 3–5 seconds let cameras focus, deployments run November→July, and field testing plus three months of engineering prove the design viable.
