Abstract
This paper presents a low-cost localization system for the high-resolution tracking of bats. The system bases on a ground network consisting of multiple low-cost receiver stations, and ultra-lightweight transmitters mounted on the bats. A main challenge of the received signal strength based localization is the limited dynamic range of the employed low-cost receivers. This challenge is solved using an efficient 2-stage differential correlation concept. It significantly improves the dynamic wrt. conventional power detection methods. In addition, this concept requires low processing power and is robust wrt. frequency offsets. Finally, this paper presents a performance evaluation employing reference measurements recorded in the rain forest of Panama.
Highlights
Bats are important indicators for healthy natural environments
For monitoring significantly larger areas we have developed a new approach: The bats carry ultra-lightweight radio frequency transmitters (< 2 g) [3], and are tracked by a ground network consisting of multiple receiver stations
The cost-saving components of this wireless sensor network (WSN) as well as the highly energy-constrained bat transmitters result in challenges
