Very interesting and good to see something not relying on a satellite that can be jammed or even shot down. I’m sure there will be many applications for this. Personal, business, gov. etc. will benefit, I’m sure. But I’m old school and always have a map handy, a state map and whatever county maps I need to get to where I’m going. It gives me a perspective of where I am, nearby roads, distances, etc. at a glance, and they don’t “re-calibrate”. Yeah, I’m an old fart.
I AM OLDER-—AND I DO THE SAME.
I’ve never used GPS anything, maps only here.
