Our Dangerous Dependence on GPS

It’s becoming hard to imagine a life without GPS.  In our quest to find ourselves and connect with others, this tool offers instant results and emergency assistance.  However, as recent events and reports point out, there can be a terrible price to pay for relying too heavily on our guardian satellites.

You may not have thought much about it, but satellite systems like the US-based Global Postioning System (GPS) are widely used commerically – not just for car navigation and smartphone apps.  According to a recent Raw Story article, GPS is used even in opening train doors upon arriving at a station, in addition to the more obvious cases of commerical flight, emergency response, and cargo tracking.  In fact, the British Royal Academy of Engineering cites a European Commission study showing “that six to seven percent of economic growth in western countries [in the EU] … is already dependent on such navigation.”

So what happens in the case of a GPS techincal failure or malicious signal jamming?  Planes and doors can still be operated safely, but the sudden loss of tracking and navigation information on a wide and persistent scale could cause a cascading effect of lost productivity and efficiency.  Financial impacts could be substantial – and that’s just now in 2011.

Even if the sky isn’t falling, the rising trend of blind obedience to GPS navigation is still unsettling.  I’m not the first to recount the recent fiasco of Albert and Rita Chretien who became lost and stranded in the Nevada wilderness earlier this year.  Attempting to take a GPS-suggested shortcut through unfamiliar mountain territory, the couple turned onto an unforgivingly muddy road and disappeared.  Forty-eight days later, a weakened Rita was found by hunters in the area; Albert is still missing.  “I think that GPS really screwed them up,” said Ryan Stowell, whose family owns the ranch where Herman [the hunter] made the 911 call. “There’s no reason for us to be up there.”

Those of us keeping to city streets may not be in mortal danger from GPS over-reliance, but there is still an unfortunate side-effect.  Take my former roommate, Adam, who could drive to the same place six times and was still not able to do it alone for the seventh because there was no nav screen telling him when to turn.  Or my recent coworkers who spent two hours getting to work six months into the job when a simple city street detour would cut the drive to 75 minutes.  If you’re only watching arrows or listening to “turn left ahead,” you’ll never learn how to read a map and make your own, often better, decisions.

As far as navigation goes, I’m a strong proponent of choosing your own directions and taking control of – and in the Chretiens’ case, possibly saving – your life.  But I have to admit I think the way GPS has revolutionized commerce and social media is pretty amazing, all dangers aside.
