Design of radiotelemetry systems for animal tracking
Abstrak
We describe the design and implementation of two low-cost, low-weight, radiotelemetry systems to measure the movement of small animals in a dense forest, where satellite positioning systems are unreliable and the attenuation of the vegetation poses several challenges. Both methods use stationary receiving stations that record the signal emitted by a portable transmitter carried by the animal. One of the methods measures the received power, while the other one registers the phase difference received by two-antennas stations. The later overcomes several difficulties that exist in the determination of the distance by the power method. We used our system to record the movement of Dromiciops gliroides, a vulnerable South American marsupial native of the Patagonian Andes, where it plays an important role in the ecosystem.
