Once in orbit, Argos-4 will join a network of other Argos instruments onboard other polar orbiting satellites to collect a variety of data from both stationary and mobile transmitters around the world. This vital information helps provide a better understanding of Earth’s physical and biological environment, including its weather and climate, biodiversity and ecosystems, as well as assist with maritime security, offshore pollution, and humanitarian assistance. Information gathered via the Argos system also enables industries to comply with environmental protection regulations.
