The National Aeronautics and Space Administration has designed a series of general purpose orbiting satellites which have the family name of Orbiting Geophysical Observatory (OGO). Each of these satellites is capable of carrying up to 50 scientific experiment devices, which transmit data to ground stations via a common telemetry channel. There are two tracking stations, at Rosman, North Carolina, and Fairbanks, Alaska, which will receive this telemetry, transmitting it to Central Control at Goddard Space Flight Center in Greenbelt, Maryland, at a data rate of up to 64 KC.
