A wide-area bird monitoring system using geographically distributed base stations

In the proposed bird monitoring system, a bird-tag, equipped with GPS, is attached on the bird body. Base stations are geographically distributed in a wide interest area to receive the GPS data sets from bird-tags using low power wireless transmission system. A data center collects the GPS data from the base stations to track the position of each bird. Simple evaluation shows that the life of the bird-tag can be nearly one year by using the proposed power saving methods. Simple analysis shows that the real-time bird tracking performance is greatly improved by the proposed position estimation method using the concept of the monitoring coverage of each base station. The real-world testbed of the proposed monitoring system is described. The preliminary experimental results show that the monitoring coverage of each base station is as far as 7 km.
