Argos is a global satellite-based system that collects, processes, and disseminates (spreads, distributes) environmental data from fixed and mobile platforms around the world.Since the late 1980s, Argos transmitters have been deployed on a large number of marine mammals and sea turtles, and it is used for tracking long-distance movements of both coastal and oceanic species.Each Argos platform features a unique 28-bit ID and the ability to transmit a short 3 to 31 byte message for each transmission.However, due to ground-based alarm system interference issues in the United States,[8] the downlink was disabled on the NOAA-19 satellite.The Argos System is served by 9 polar orbiting satellites at an altitude of 850 km and completes a revolution around Earth approximately every 100 minutes.
