What does this mean? Now, consumer-grade GPS units will have a positional accuracy several times better than they previously did. SA limited single-unit GPS fixes to typically no better than 50-100m accuracy. Estimates are that with SA off, these units could be from 0m to 70m more accurate. Here is the results of a quick search relating to these topics: http://www.google.com/search?q=gps+sa+selective+availability+accuracy+30+met er&meta=lr%3D%26hl%3Den This is exciting stuff for the GIS and remote sensing fields.
