But there is still going to be cumulative error and drift, right? Has this system reduced the cumulative error so that in some pedestrian use cases it is accura

But there is still going to be cumulative error and drift, right? Has this system reduced the cumulative error so that in some pedestrian use cases it is accurate enough?
- AstralStorm 9y agoBoth. Long term drift will be extra challenging to correct as the cumulative error is staircase. (Beta distribution) What this is is actually a step counter, combined with step length and heading estimate from an accelerometer w/ gyroscope plus compass. When the counter makes a mistake, the effects will be catastrophic.
