Solar Powered Animal Tracking Tags with GSM Telemetry

Abstract

This thesis describes the development of a solar energy harvesting system for lightweight wildlife tracking tags that use GSM cellular communication for telemetry. An energy harvesting system was designed and implemented in combination with a replacement firmware solution that controls the whole tag at a minimised energy cost. The design was tested both in the lab, and during deployment on Northern Royal Albatross. The solar energy system and firmware significantly improved the tag lifetime allowing effectively indefinite deployment. This solution also allows a greater GPS fix frequency, enabling zoologists to obtain a more detailed understanding of a tagged animals’ behaviour.
