The Argos program has several applications. Historical and internationally known, this satellite service allows to track many species of animals using beacons. Data is retrieved thanks to the ARGOS satellite constellation. Animals tracked can be birds, marine animals (including turtles, fishes, dolphins, etc.), and terrestrial animals (such as bears, for example).
