Thousands of animals are tracked with Argos transmitters, including birds, marine and land mammals

By combining the data acquired with their location, Argos enables biologists and scientists around the world to improve their understanding of animal behavior, such as their movements, foraging strategies, reproduction and the way they adapt to their surrounding environment.

Birds

About 4500 birds are tracked every month with Argos. Thanks tominiaturized transmitters which are becoming lighter and lighter (some weigh less than 5 grams), and to the sensitivity of receivers on satellites, which can record very low-powered transmissions (150 mW), it has now become possible to track and locate new species, whose migratory behavior has not yet been determined.

Terrestrial mammals

About 2000 land mammals are tracked with Argos each month. Scientists and biologists use the ARGOS system to understand the distribution of animals in a given territory in order to protect them more efficiently. Robust equipment that can withstand the most extreme environmental conditions is specially designed for each species.

Marine Animals

There is a vast range of pelagic species below the surface of the seas and oceans. Some strike us as fearsome, others as fascinating, others again we know little about, and some we fish, often intensively. In spite of the apparent difficulty of observing these animals, extremely robust and reliable Argos transmitters can record for many months the depth and temperature of the water through which they move and transmit this information to specialists on land who can then either directly track or reconstruct an animal’s trajectory.

Symbolically important and enigmatic animals, marine turtles fascinate both the scientists investigating them and the general public. Between 800 and 1000 marine turtles migrating across the oceans are tracked via the ARGOS satellite system in order to determine their trajectories and identify their geographical distribution; the data are then correlated with other sources to analyze their behavior at sea or on land. The overriding aim is to better protect local or regional turtle populations that may be in danger of extinction.
