No modern car (nor any smartphone) is considered complete without some sort of navigation product. Indeed, even my wife’s bottom-of-the-line, not-so-smartphone has a cell-tower-based navigation system. Ironically, my wife never uses it and is never lost, while I have no navigation system on my phone and am lost all the time. Wait, what were we talking about again? Oh yes navigation and global positioning. A group of researchers have come up with an elegant, laser-based method of helping GPS systems determine where we actually are. via ars technica
