I always wondered if the positioning principles in GPS and other satellite positioning systems could be applied to a system of tower's on the Earth's surface, that broadcast similar signals. It seems like this would be an affordable way to produce a "local positioning system" and the technology for radio signal generation, broadcast, reception and processing already exist. I wonder if this would be a way to overcome the challenges of positioning in urban canyons or heavy forest canopy. You might even be able to install the signal broadcasters on existing cell towers, water towers, and other structures, which would greatly reduce the cost. But maybe there is a technical reason why this will not work.

In some ways I wish the US would create some controversy so it could re-invigorate Galileo. The EU seems to be increasingly disinterested in a competing system and removing the SA feature from satellites just makes Galileo less interesting. At least there's the Russian GLONASS system being retooled and China's Compass system (which is still undefined).
