AubieSat-1 is an American technology testing satellite with Cubesat architecture. The main purpose was to test two different solar cell envelopes and their aging in space over time. To this end, the battery data was recorded and analyzed over a long period of time in order to research the behavior of batteries and solar cells under space conditions and to draw conclusions about the construction of other satellites. It was built by students from Auburn University .

The satellite was launched on October 28, 2011 as a secondary payload with a Delta II rocket at Vandenberg Air Force Base . Since the satellite communicates in the amateur radio frequency range, the satellite was also assigned the OSCAR number 71 after its successful start .

After the start, communication problems arose because one of the satellite's antennas was apparently not deployed. The problem could be overcome by using a more powerful transmitter in the ground station. Aubiesat-1 sent readings of the solar cell voltage for several months.

As an amateur radio satellite , the satellite transmitted telemetry data in Morse code under the amateur radio call sign KI4NQO on the frequency 437.475 MHz . Its COSPAR designation is 2011-061E.
