gotta align the “platform” to Earth or space coordinates first.
The new sensors are orders of magnitude better than the ones we saw 60 years ago when inertial systems were all the rage. So drift rates and angular resolution have also improved. Prolly biggest thing that made all this possible is much better clocks. Yes, clocks. And chips that worked at ghz versus MHz or kHz.
The crystal oscillators and means to count each vibration improved and got better. So in late 60’s we saw watches that only lost seconds per month! And it only got better.
GPS is best example of what a super time system can do. We get mm position data for mapping by using the rf carrier wave and resolving the phase angle!
You can can screw up the iPad or iPhone alignment by rotating it about 40 or 50 degrees the first minute or two once it is on. Makes for a good science project your grandkid could do.
