$50SAT was developed by Bob Twiggs at Morehead State University (MSU) along with three other radio amateurs and was used to train students.[3] The satellite transmits telemetry data in various operating modes in the 70 cm (28 in) band. It is based on the PocketQube design for very small and inexpensive satellites and measures 5 × 5 × 7.5 cm (2.0 × 2.0 × 3.0 in) (1.5 CubeSat).[4] After several months of problems due to low battery voltage, $50SAT finally dropped below the 3.3 volts required for data transmission on July 19, 2015 and thus ceased operation.[citation needed]
