Argos Beacon for Bird Satellite Tracking
MRBA-25G is an Argos PTT beacon for tracking birds over 800g. It uses solar panels and miniature electronic components for long-term monitoring. To avoid a change in behavior of the animal on which it is placed, the beacon has been designed to not exceed 3% of the total animal weight. MRBA-25G is also distinguished by a very small footprint, advanced technical performances and a reduced price to draw more animals with the same budget.
For a faultless accuracy of positioning, Syrlinks has embedded a GNSS receiver (GPS / Galileo) in the beacon. The position of the animal will be permanently known with positioning accuracy below 10m. Finally, a number of sensors have been fitted to meet the needs of scientists depending on the species tracked: accelerometer, temperature, pressure, brightness ...
MRBA-25G is a very complete Argos PTT beacon and offers great opportunities for scientific monitoring of animals both for one-off follow-ups and for large tagging campaigns.
