> the military GPS is different from the Civilian GPS
I remember reading at some point that the civilian GPS was randomly offset so as not to give extremely accurate coordinates like the military GPS does. I thought that was interesting, if true.
- pdonis 7y agoThe US used to intentionally degrade GPS signals available to civilian receivers as compared with those available to military ones, but it stopped doing that in the 1990s. The biggest difference now between military and civilian GPS is that military receivers use two frequencies, whereas most civilian ones only use one (since using two costs more).
