New GPS technology such as the SIRF III GPS chip, built into a cellphone (G3, CDMA, etc)needs only a slight signal from 3 orbiting GPS satellites to get a fix on the location of the cellphone. In some instances the chip only needs 1 second to determine it's latitude and longnitude to report the position via the cellphone system. Very similiar to AVL or Lojack but much much more sensitive!!! Excellent Job!!
