you'd need to measure against something, since you probably won't have GPS and dead reckoning probably work very long

- MR4D 8y agoInertial guidance on a cellphone was written up last year. It's clearly a work in progress, but it's a good start. HN link to it is here [0]. I'd bet that if this continues (and I presume the military would want to ensure it continues if only for redundancy purposes), that we'll have accurate inertial guidance on our phones in a decade.

- cwmma 8y agothe thing about dead reckoning is that anything less then perfect tends to have degraded usefulness after a while unless supplemented with some outside data to reference again. Now thing about a soldier underground who might be subjected to explosions nearby, shooting, being shot at, having to dive for cover and these are all things that are going to screw up any inertial guidance system which is why the suggestions of paint or something make a whole lot of sense.
