The first satellite that formed our modern GPS system was launched in 1989 and the system was declared fully operational in 1995. However, while civilians could use the GPS system, the accuracy was intentionally degraded for “national security” purposes, which practically limited use to government agencies. As the national security implications were reconsidered, in the year 2000 intentional degradation to civilian use was ended, making GPS much more useful for common purposes. Within a few years, affordable GPS handheld and in-car navigation systems started to become commonplace.
Suddenly the way we navigated started transforming. No longer did we need to write down vague directions or buy maps when traveling. Our navigation systems could tell us how to get virtually anywhere and how long it would take to get there. This made travel easier but also safer, since we knew where we were going and getting lost was not the problem it used to be. Soon after, the mobile device revolution brought GPS along with it. By recent estimates nearly 80% of Americans own a smartphone, so by association GPS is virtually in everyone’s hands today. With how easy GPS navigation makes traveling and to the extent it keeps us safer, it is hard to imagine living without it.
