From what I understand, Lorentz transformations can determine the dilation of time with relative speed. (Of course I could be wrong). How does the GPS use this to function?

My brother is getting bailed out jail and they told me he has to wear a gps once he gets out and that him or the family would have to pay for it? How much is that?

If I need to make a portable device which you can carry around with you to give the exact location, altitude, climb and descent.

What electronic chips hardware will i need to make a portable GPS system?

Is there a need to make a payment to some company to use GPS?

I am looking for a nice, decent GPS, nothing too pricey, but a portable one, that has Mandarin Voice playback-turn by turn navigation and also includes Canada. I like the thinner ones as opposed to the bulky looking ones.

Thanks!

I’ve been looking at the HTC Touch Diamond and IPhone 3G and I noticed that IPhone 3G only has AGPS while Diamond has both.
I did a search and found out that AGPS is assisted by cellular towers and etc to pinpoint location more precisely.

I’m curious as to whether will using AGPS and GPS incur charges from my network provider?

I bought a new sony ericsson c903 recently, and I saw that there was a GPS function. The thing is, how do I use it? I used status checker and everything, but I don’t have the internet cause I’m on prepaid. So does that mean I can’t use it at all?

My husbands employer had a GPS put in everyone’s truck at work to see where they are going. Is there any way of blocking the signal so that they can’t pick up on where he is.

GM vehicles all have OnSTAR, which has a GPS tranciever in the electronics package. Is taking over GM the start of the End times, where everybodys car can be tracked by the government. How much longer until we all need to have a “paychip” inserted into our hand.

When I touch the GPS screen, every single time the frickin thing beeps!!! I need to know how to turn it off so I can have some peace and don’t annoy everyone.

Michael asked:


I’ve read the wikipedia.com entry for GPS and some of it just doesn’t gel with me.

Anyone have any pointers to a description online on how most gps receivers can calculate the correct time that an interested “newbie” would appreciate?

I’m also interested how a gps receiver can discriminate satellites’ C/A trains with multiple radios when all satellites are transmitting at the same frequency? Wouldn’t all the radios (like on a 12-radio GPS receiver) be listening to exactly the same thing? Seems like they’d all be stepping on themselves and not be separable.
