The Cryologger Ice-Tracking Beacon (ITB) and Automated Weather Station (AWS) are based on the open-source Arduino platform ( and built using low-cost, do-it-yourself electronics that can be easily modified to meet the needs of the end-user. Code was written using the Arduino Integrated Development Environment (IDE) and benefits from the availability of community-generated libraries.

Planned for extended deployments in harsh Arctic conditions, the Cryologger can provide long-term measurements of GPS position, temperature, pressure, pitch, roll, tilt-compensated heading and battery voltage and measure external instruments such as anemometers, temperature and humidity sensors, pyranometers, ultrasonic sensor and more! Data are transmitted over the Iridium satellite network at specified intervals and can be remotely updated based on the desired sampling frequency.
