50 SAT



50SAT, also called Eagle 2, is femto-satellite to test miniaturized components in a satellite built to the 1.5P PocketQube form factor (7.5 cm × 5 cm × 5 cm). It is a collaborative project between collaborative education project between Professor Bob Twiggs, Morehead State University and three radio amateurs, Howie DeFelice (AB2S), Michael Kirkhart (KD8QBA), and Stuart Robinson (GW7HPW).

50SAT is a PocketQube micro satellite made from commercial electronic components and designed to fit in a 50 mm cube. The concept for the satellite is to see if a micro radio transceiver, the HOPE RFM22, is sufficient for transmitting and receiving data from a satellite in orbit. The satellite transmitted a call sign in 15WPM Morse, send some environmental data as 60WPM Morse as well as transmitting a data packets containing information about the satellites operation. The satellite listened for incoming data packets in order to provide a transmit on or off command functionality.
