As electronics have dramatically reduced in size and composite materials become more common, the opportunity for smaller platforms have become widely available, both publicly and privately. With the miniaturization of platforms and instruments, comes the challenge of maintaining on-orbit performance and calibration. This includes understanding how smaller instruments will behave on orbit and react to the harshness of space. Miniaturizing instruments does not mean we have to sacrifice performance and quality for size and cost. It means that SmallSat and instrument providers have to be more creative and resourceful as they design and build these architecture types. In this presentation, we’ll explore how SmallSats and miniaturized instruments come to be, from concept to launch, what are the challenges we face to maintain high performance, and learn how across the industry, from operational weather to defense, these tiny technologies compliment current constellations.
