    Default Satellite singal

    Is there a difference in the satellite signal versus cell tower signal in terms of effect on a human health?

    Well, the NAVSTAR GPS satellites orbit the earth at ~12,600 MILES, and cell towers are spaced withing several miles of us, so it would, I think, be safe to say that cell signals are much more likely to have an effect. Also, it is the cell phones transmitter that is a concern--a GPS receiver is just that, a receiver, just like your FM radio.

    If you're interested in GPS technology, the Wiki article is a good place to start learning:

    Ah, so that's why you hear people complain about drivers using their cell phones while driving, but you never hear anything bad about them using their GPSr...

    Welcome to the site, gpsfaq. If you don't mind my asking, how is it someone with a web site about GPS information comes to geocachingmaine.org to ask such a question?

    And it's the microwave signals from tower to tower that are the most dangerous (the way it was put to me when I was doing the refrigeration on the towers "don't stand in front of the microwaves because if they become active they'll make your *insert name for male reproductive organs here* shrivel up like rasins...*) the microwave signals excite water molocules causing them to heat up and evaporate...

    i heard a story on the news a few years back, about a lady who lived near a tower, there was a malfunction with the tower, and it was broadcasting a low frequency microwave signal and pretty much fried all the vegitation in her yard...

    This could be "rural legend", but I've been told that when testing the Over the Horizon radar in Moscow (Maine!) - see our "Over the Horizon" cache - small animals in front of the antenna were toasted quite nicely.

    Default Thank you for response

    Someone asked me this question, but I am not too much detailed on terms of signal strengths and etc... any time you get reciever you are emplifying signal as a result waves are stronger, the good things is that its not next to your body but far away attached to a car window.

    Default Researching

    After researching for some time I am able to report that signal is quite harmless, but no definitive study was done, so use GPS with caution.

    I do not agree with what you say.

    The GPS signal from the satellites is around you whether you have a GPS or not, just as radio and TV and received cellphone signals are around you whether you are using them or not. Of these only a cellphone is a transmitter and therefore may have a stronger signal when using it.

    I do not believe that any caution is necessary when using a GPS except to pay more attention to where you are stepping than to the GPS screen. Watching the screen while stepping off a cliff hurts, a lot.

    Unless of course, you have some fluffy, low frequency radio signals to break your fall.
