Mobile-BAT-A Novel Ultra-Low Power Wildlife Tracking System

Area of Science:

• Ecology
• Bio-logging
• Wireless Sensor Networks

Background:

• Tracking animal movements is crucial for ecological research.
• Existing methods often lack the spatiotemporal resolution or long-term deployment capability needed for certain species.

Purpose of the Study:

• To introduce a novel, ultra-low power system for high-temporal-resolution animal movement tracking.
• To enable long-term, detailed movement analysis in small or migrating animals.

Main Methods:

• Utilized a miniaturized software-defined radio (2.0 g) to detect cellular base stations.
• Employed a probabilistic radio frequency (RF) pattern-matching method for position estimation.
• Integrated a long-lasting battery for extended operational runtime.

Main Results:

• Demonstrated a system size equivalent to two stacked 1-euro coins.
• Achieved an operational run-time of close to one year in field tests.
• Verified successful deployment and data acquisition on European bats.

Conclusions:

• The developed system offers unprecedented spatiotemporal resolution for animal movement tracking.
• Its small size and low power consumption make it suitable for a wide range of small and migrating species.
• The technology facilitates advanced ecological and behavioral studies through detailed movement data.
