Does anyone know when GPS signals first became available for use by private enterprise? Was it prior to May 1988, or afterwards?
I may need this information to fend off a groundless, analysis-free
103 rejection at the patent office. Wikipedia doesn't really spell it out. I want to know when manufacturers of commerical electronics started (legally) using GPS in their product designs. Surely there was some government document authored somewhere that made the GPS system available for civilian use...??We may not end up using this argument (since we have a few that are much better), but it would still be nice to have the answer in the bag.
Thanks!!
