Nuevo sistema para monitorizar el movimiento/localización de animales salvajes pequeños mediante transmisores de radio y receptores digitales


Oferta Tecnológica
Un instituto alemán ha desarrollado un proyecto de código abierto que consiste en un sistema para monitorizar el movimiento de animales salvajes pequeños (<10g) mediante transmisores de radio (<0.5g) y receptores digitales. Los receptores comunes son reemplazados por receptores digitales de mayor rendimiento, permitiendo un seguimiento automático de la señal del transmisor. Este sistema ofrece como ventaja la posibilidad de que un usuario sin conocimientos técnicos pueda ensamblar y utilizar el equipo a través de un navegador. El instituto busca socios con el fin de establecer acuerdos de financiación e investigación.


New system to monitor the movement/location of small wildlife animals using radio transmitters and digital receivers
Aim of the open source project carried out by a German institute is a new system to monitor the movement of small wildlife animals (<10g) using radio transmitters (<0.5g) and receivers. Within the system commonly used receivers are replaced by digital receivers with better performance, allowing automatic tracking of the transceiver´s signal. One focus of the system is, that non-technical users can assemble and operate it via a browser. The institute looks for financial and research agreements.
For the tracking of small animals (bats, insects, birds) almost the same technique is used today as in 1960. Only the size and the power of the transceivers have been improved. The receivers have remained the same and although, today digital low-cost receivers are standard they are rarely used for wildlife tracking because it involves programming. For small wild animals, it is still common to use two teams to draw up a motion profile by means of manual cross bearing which involves a directional antenna (antenna with a preferred signal direction) and an analog receiver. This process is very error prone, time consuming and could be replaced by automatic cross-bearing.

The open-source project of the German institute aims at the development of a low-cost system to draw-up motion profiles of wild animals by means of low cost USB (universal serial bus) receivers. Since a few years, low-cost, programmable mini-computers and software defined radios have been available, which can replace the traditional analog receiving system. These are already available on the market and easy to install. It lacks therefore only the software-technical implementation, so that a wide range of unexperienced users can set up the new system.
Instead of using the usual receivers the institute uses a software defined radio USB dongle and connects it to the antenna. The dongles can be directly connected to a computer. For field application, it is best to use a single-board computer such as e.g. a Raspberry Pi mini computer

A focus of the project is to enable especially non-technical users to operate the system. They only assemble the parts, download the image file, copy it on the SD-card and plug it into the Raspberry Pi. To start the receiver, the users connect to the wifi hotspot and tune to the frequency of the radio transmitter using their browsers. To listen to the emitted beeps by the radio transceiver they just need to plug in headphone or loudspeaker.

The German institute is looking for a financial agreement with partners looking to invest into an open source technology to track wildlife which might be interesting for their own use. Benefits are lower developing costs and time savings on the other side there is no warranty granted.
Furthermore, they are looking for a research co-operation with developing partners who are financed by a third party and are looking for a software development project or with researchers interested in the free application of the system.

Advantages and Innovations:
Overall the open source system to track wildlife animals is cheaper and more efficient than the currently used manual methods:
- software defined radios only cost a fraction (around 10%) of traditional analog receivers
- automatic cross bearing is much more precise than manual cross bearing
- with manual cross bearing it is only possible to follow one animal at a time, with automatic cross bearing it is possible to follow several animals at the same time
- non-technical users can assemble the system and operate it via a browser.
Stage of Development:
Under development/lab tested
CommeR Statunts Regarding IPR Status:
No IPR applied for. The system will be published using an open source licence (GNU,MIT)
