The micro sun sensor is a state of art miniaturized digital sun sensor. It was originally developed as a new technology at JPL from 2000-2004. It was base lined for the Mars Science Laboratory Mars rover and was qualified for an MSL environment and requirements (but not selected). The micro sun sensor has been a pathfinder for a new generation of sun sensors and has inspired a handful of other similar developments around the world. A prototype unit has been balloon tested to 125,000 feet. The micro sun sensor has now been flown on the FOP UP SL-9 sounding rocket. A micro sun sensor will be delivered Georgia Tech's Prox-1 Mission in 2015.
