The earth is constantly monitored by several satellites operating in the earth exploration-satellite service (EESS)[1] or space research service (SRS). These artificial satellites have onboard space radio stations from which they gather data. The data is transmitted back to earth via feeder links. This article lists a number of current active Earth observation satellites and their downlink transmission frequencies.
