How perfect is GPS? You be the judge

August 14, 2017  - By

In the July and August issues of the magazine, the “Out in Front” editorials held forth on the perfection or lack thereof in the GPS signal and service.

Now it’s your turn!

Give us your opinion at and we’ll publish the results in the September issue. And you’ll gain entry to a random drawing for a $50 gift card.

The question is: How close to perfect is GPS performance?

And your choices are:

  • Absolutely perfect. 100 percent.
  • Nearly perfect. The space segment functions flawlessly. The only problems are with jamming and user equipment.
  • Almost nearly perfect. There have been a few hiccups in space, then there’s jamming, and user equipment weaknesses.
  • Not nearly close enough to perfect — but pretty good.  The (admittedly rare) operator miscue, jamming, spoofing, and other exploitable user equipment weaknesses.
  • Fair, but a long way to go.  All the above cited problems, plus lack of signal reception under canopy, urban canyons, indoors.
  • Not a passing grade.  But it’s the best I have, so I grit my teeth and use it.
  • Pretty poor if you ask me. It just does not meet my requirements.
  • Other (please specify)
