Spanish Researchers Discover...Inertial Navigation

This Invention Will Make Your GPS Not to Suck In Cities

Right now your GPS sucks in cities but, soon, that will change. Scientists have developed a new system that increases its accuracy by up to 90%—it can tell where your vehicle is within an amazingly low margin of error of just three to six feet. Right now, the error margin in urban driving can be more than 160 feet.
...
Developed by researchers at the Universidad Carlos III of Madrid, Spain, the system uses a clever combination of software and six sensors—three accelerometers and three giroscopes—which combine in real time with the GPS data. In case of signal degradation, the system will automatically correct the position to the accurate coordinates. It can even track the car with extreme accuracy in the case of complete signal loss.

Wow! That's amazing!

Ummm...it's called an Inertial Navigation System (INS) and it existed long before GPS did.

I just find it really funny that if you can get within 200' of your target that you can't look out the window or look up and see where you are.

Do you REALLY need accuracy down to 3'?

they've got to be kidding...right??

but seriously, do most private GPS units have INS that work when GPS is down? I'm not sure

I like to know what side of the road I'm on when I zoom in!

Seems the Spanish are getting more advanced in techy stuff. Just read where someone who speaks Spanish (so I'm assuming, wrongly, Spain...) posted about a huge security hole in Apple's iOS6.

I went to a Navy school for the Nav system on subs back in '78

It's so blind people can drive

Looks like Cambridge Consultants also just discovered it...
