Copernicus is a plan to assemble information from environmental satellites, air and ground stations. This information is to be used to monitor Earth conditions relating to temperature and other environmental factors. Copernicus has both environmental and national security implications. With Copernicus, the European Union fulfills its commitment to the Global Earth Observation System of Systems (GEOSS).
Sentinel-1A was transported to Kourou, French Guiana for launch. It arrived at the launch pad on 25 February 2014. Launch took place on 3 April 2014.
