"This PhD project involves the development of an animal tracking system utilising UAVs and Mataki wireless GPS tags. These devices are Open Design and Open Source, offering a cheap, lightweight and very powerful technology for wild animal tracking.

Mataki systems are usually enclosed in a collar or tag that is attached to the animal in such a way that after a period it will bio-degrade and fall off. The device periodically records scientifically important data regarding the animal’s behaviour. A typical Mataki is approximately 8g in weight and has: a microcontroller, a radio transceiver, a GPS receiver, a three-axis accelerometer, a pressure and light-level sensor. Thus over a period of time the device builds up a time-stamped history of the animal and its movements/position.

Because of the presence of the radio transceiver and micro-controller the Mataki can be programmed such that when one animal equipped with a device is in close proximity to another similarly fitted, the two devices exchange data. Thus it is possible that each individual animal in a group may be carrying the data of the entire group. This means that only one device needs to be recovered and uploaded from to garner a great deal of high quality data.

Within this project it is proposed to design a Mataki device which is modified for aerial use from a UAV. The idea is to design a specialist UAV to carry that device into proximity with a subject animal and so capture the data from it in the same way that Mataki devices work on an animal-to animal basis. This would have a number of significant advantages. Firstly it would facilitate data retrieval without having to recover the physical device. Secondly it would make possible the regular reacquisition of data at intermediate stages whilst an experiment was on-going.

Initial work would involve the design a new type of UAV capable of long endurance, extreme low-noise level, flight. This device would be capable of loitering in the region of a group of subject animals for up to one hour at a height of approximately 100 feet. This represents a significant technical and innovative challenge. The Mataki design would then be modified to work via the UAV’s own on-board telemetry system, thus allowing both upload of data from a ground based subject animal and simultaneous transmission to a user ground station some hundreds of metres away. Again this system integration is a technical challenge and it is believed that this would be the first time that UAV control systems have been adapted to relay ground based data of this sort."
