Stratosphere is a highly versatile avionics stack designed for a variety of Remote-Controlled (RC) vehicles such as planes, model rockets, and drones. Stratosphere is designed for verstaility, allowing for usage as a standalone stack and alongside off the shelf modules (VTX, GPS, etc), servos and ESCs.
