The Spartan Packet Radio Experiment (SPRE) was an Amateur Radio communications experiment that flew on the Space Shuttle Endeavour's STS-72 mission as part of NASA's Spartan/OAST-Flyer spacecraft in January 1996. ^[1] The experiment was intended to test the tracking of satellites via amateur packet radio ( Automatic Packet Reporting System), and was designed and built by the Amateur Radio Association at the University of Maryland (W3EAX). ^{[2] [3]} Required GPS data for the experiment was provided by another portion of the Spartan payload. ^[2] The operating mode was FM, AFSK 1200 baud packet radio, transmitted at 145.550 MHz. ^[4]
