This session will cover the technical and design challenges in developing an autonomous Linux-powered Arctic buoy. This system is a low-cost, COTS-based, extreme/harsh environment, autonomous sensor data gathering platform. It measures albedo, weather, water temperature, and other parameters. It runs on a custom embedded Linux and is optimized for efficient use of solar and battery power. It uses a variety of low-cost, high-accuracy/precision sensors, and satellite/terrestrial wireless communications. This session will discuss using Linux in this embedded environment, and how to address and solve various issues including building a custom kernel, Linux drivers, frame grabbing issues and results from cameras, limited power challenges, clock drifts due to low temperature, summer melt challenges, failure of sensors, intermittent communication issues, and various other hardware and software challenges.


This presentation will help existing and new embedded system designers and developers in understanding design challenges posed by the environment and how to overcome them. Example, in order to conserve battery power, the system is put to sleep with a fixed wake-up time. Extreme cold temperatures (-40 C/F) cause clock drift which affects wake up cycle. The audience may find useful the solutions to such challenges.
