What a great project. I wonder how the modern sensors stack up against the military version in times of jitter and drift, that might cause some surprises. Larger sensors have a lot of inertial filtering compared to smaller ones.
I also think that the MTBF target the original had will be vastly exceeded by this replica due to the reduction in component count, but it will probably be more susceptible to bitflips. But you won't be flying that high if you put this on a drone. Please post future updates.

Now we got it on a %50-100 FPGA board.
Half the size of a credit card. I guess the original computer onboard was 12-15 kgs
Late in Sweden, back tomorrow (CET)
