I'm looking into the FMS Co-Pilot system....not the whole system, just the sensor.
I think it should work just fine.
There is sufficient BW in the sensor to support a 5 revolution per second spin rate. With a little help, it might do better.
Using the cross-coupled (subtractive) sensors, any tilt will yeild an offset signal.
Spin will turn the signal into a sin wave output.
Just detect the magnitude of the peak of the sin and compare to a threshold.
Inhibit the sustainer ignition if it's over a preset level....easy to do with a Misson Control altimeter.
So far it looks good on paper.
I'll let you know later this summer (when launch season starts) how it works.
