Due to things like testing, software development, and careful construction, it had been designed in the early 1960s. Anyway, the IMU for it was "a little bit smaller than a basketball". The gyroscope had 15 bit resolution, and the document that I found that talked about the accellerometers inferred that they likely had 12 bit resolution. (I suspect that the scarcity of documentation was a result of it having been an improvement on the IMU for the top secret Polaris submarine launched missle.). Anyway, the gyro for the LSM6DSV16X is a bit better (pun intended), and the accellerometers are about an order of magnitude better -- and the device is <em>smaller</em> than the Qwiic connector! Without digging further, I suspect that the on-board processing power of the LSM6DSV16X far exceeds that of the total on-board computing power for an Apollo spacecraft!</p>
