GPS To Go To 31cm Resolution
The US GPS constellation will be showing features smaller than 50cm following the lifting of technical restrictions.
The imaging firm Digital Globe applied to the US Department of Commerce for the restrictions to be lifted and now says that GPS will be able to show 31cm-sized features.
Digital Globe will now launch new satellites to take advantage of the finer resolution. The first of these will launch in August.
The finer resolution will be available for general use.
