Re: looking for high quality GPS
Definitely not obsolete. It is called Differential GPS and is still used pretty heavily, with the FAA's Wide Area Augmentation System being a rather impressive example (remote stations measure variations in GPS signals and relay that data to master stations, which then send the data to geo-stationary satellites to relay the data to navigation systems).
