I just purchased several GPS units that I thought were top of the line. They work great indoors but you have to be close to the windows when you are indoors. This is a great improvement to the previous generation GPS that would not work indoors at all.
Good news is that people are already working on th enext generation GPS that would work anywhere indoor – be it basement or elevator or in the bathroom. Yes, those hollywood movies where bad guys see exactly which room the hero is located on a high raised building is not going to be animation for too long. A silicon valley startup company has developed and successfully tested this new technology GPS units.
Check out details from the ROSUM company website. They are combining old TV signal technology with the GPS technology to make this work. It’s awesome.
