Apparently any GPS module made in the US and exported is classified as a munition if it is:

Capable of providing navigation information under the following operational condition:

  1. At speeds in excess of 515 m/sec (1,000 nautical miles/hour);
  2. At altitudes in excess of 18 km (60,000 feet).

Would the GPS still be usable above 18 km or while travelling more than 515 m/sec?

I have a Droid Charge.

Is this a real question? – Lie Ryan Sep 12 '12 at 6:21
Yes, it is a real question. – Robz Sep 12 '12 at 7:27
It may be a real question, but it's not on topic for this site. This isn't a problem on your Android device; it's a question of law. – Al E. Sep 12 '12 at 12:30
@AlEverett I've rephrased the question. I think it's on topic now. – Richard Borcsik Sep 12 '12 at 14:00
Er... How often do you move in such a manner? – SaintWacko Sep 12 '12 at 18:16

No it's not.

Commercial GPS receivers (like the one in your phone) only work below 18 km and below 515 m/sec. The rationale behind this is that this way they can't be used in ballistic missiles (yes, I'm serious.)

In order to circumvent this you'd need to flash a different firmware to your GPS chip, if you didn't do this you're safe. No current android device ships with munitions grade GPS receiver.

@Zuul Anything specific you're looking for? I've found that arms regulations are not the most documented things in the world :) – Richard Borcsik Sep 12 '12 at 10:37
Someone came up with these limits to the civilian world. Somewhere, there's a paper or an article about it that one can read to better understand the surroundings of this issue :) Ultimately, I'm trying to have your answer corroborated by "official" documentation :D (I've already up-voted, that should suffice to tell you that your word is enough for me) – Zuul Sep 12 '12 at 10:42
@Zull, please my answer to the question…. – Narayanan Sep 12 '12 at 10:53
