Correct, but not totally. The introduction was by the "Family & Friends" feature. Where is my girl friend, where is my husband, where is that bar where the boss wants to meet me.
The E911 system was based on signal time domain to cell sites when first introduced because the chips were not yet available to get real time GPS in the phones. Therefore a three site triangulation was used based on signal strength. If I remember back three years (hard :-) ) like maybe 300 yards. This was a stall tactic by the cell companies only to save dollars until the phones and standards were set. Now if we look at the code methods, we are, (sorry they) are able to get to 30cm in covert conditions. If you think this is extreme, in 1996 I wrote an article for a Coast Guard News Letter that described how a ship could be brought to its berth, totally under GPS control. -----Original Message----- From: Terry Blanton [mailto:[EMAIL PROTECTED] Sent: Thursday, March 08, 2007 2:21 PM To: vortex-l@eskimo.com Subject: Re: [Vo]: Is Big brother watching?

No one triangulates any more. It was a requirement of the Enhanced 911 service. Allegedly, I can turn this feature on and off. . . allegedly. Terry
