===Portable Geoceiver=== <!-- Target of Geoceiver redirect -->
A portable version of the ground station was called a Geoceiver and was used to make field measurements.  This receiver, power supply, punched tape unit, and antennas could fit in a number of padded aluminum cases and could be shipped as extra cargo on an airline.  Data was taken over a period of time, typically a week, and sent back to the Satellite Control Center for processing.  Therefore, unlike GPS, there was not an immediate accurate location of the Geoceiver location.  A Geoceiver was permanently located at the South Pole Station and operated by United States Geological Survey personnel. Since it was located on the surface of a moving ice sheet, its data was used to measure the ice sheet movement.  Other Geoceivers were taken out in the field in Antarctica during the summer and were used to measure locations, for example the movement of the [[Ross Ice Shelf]].
