You're still not saying anything of value that I didn't already know and mention.
Anyways, to me it seems that a $5 off-the-shelf chip can do anything a guided missile would need to know where it isn't.
- more than high enough sample rate for a PID that drives the rocket
- great deg/s and max g measuring ranges
- enough g resistance to survive rocket motor startup jolts
- very wide operating temperature range
- ready to interoperate with external sensors like magnetometers
- etc
If anything these mobile chips have a bunch of unnecessary extra features like low power pedometer mode and hand gesture recognition algos. But they're completely programmable for any task.
What else would it need? Maybe the sensors' precision/sensitivity aren't enough?
