Comment So, Dead Reckoning? (Score 1) 65
This apparently calculates future positions based on movement direction and velocity changes from a known position, a process known as dead reckoning (https://en.wikipedia.org/wiki/Dead_reckoning). I see two problems with this:
- You first need to have it at a known position, and give it that position;
- Its calculation of changes in position and velocity must be perfectly accurate.
The second one is the main problem. Unless it's perfectly accurate (unlikely?), it'll need recalibration often/occasionally, and how do you do that?
