good night everyone.
I was talking with some colleagues about Pico and Nano Satellites, as we enter the point which best microcontroller to use this type of equipment, the CubeSat team (www.cubesat.com) uses the MSP430, but the justification presented unique is that it is the one who endured the requirements for the type of use.
I know that commercial and military satellites are using your own version and that some are even built on substrado sapphire to withstand radiation.
Please could someone guide me where to get information on options based on Cortex-M or Cortex-R which are suitable for these studies?
