The goal of this mission is to demonstrate the capability of software defined radio (SDR) in space communication applications by transmitting between the RockSat-X sounding rocket and the Virginia Tech Ground Station (VTGS) in Blacksburg, VA. The packets transmitted contain gyroscopic, acceleration, pressure, and temperature data collected aboard the payload. This mission is a proof of concept for low-cost and highly flexible transceivers for spacecraft.
