$50SAT

$50SAT (also known as Eagle-2, OSCAR 76, Morehead-OSCAR 76 and MO-76) is an American amateur radio communications satellite. It was launched on November 21, 2013, with a Dnepr launch vehicle from the Dombarovsky Air Base, in Orenburg, Russia. It was part of the UNISAT-5 satellite program by GAUSS (Group of Astrodynamics for the Use of Space Systems).

$50SAT was developed by Bob Twiggs at Morehead State University (MSU) along with three other radio amateurs and was used to train students. The satellite transmits telemetry data in various operating modes in the 70 cm band. It is based on the PocketQube design for very small and inexpensive satellites and measures 5 xx (1.5 CubeSat). 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.

Objective
The objective of $50SAT was to see if a viable satellite could be built to the PocketQube standard.
