U-blox will introduce a new GPS chip at 3GSM sensitive enough to determine a location indoors. The u-blox 5 is able to read extremely weak signals, down to -160 dBm, from either the GPS or Galileo satellite network. This would allow users to get an accurate location indoors or in urban canyons where signals are normally weak. In addition to not requiring a powerful signal, the u-blox 5 does not require much power either, making it a possible choice for mobile device manufacturers. Currently no major handset manufacturers use u-blox chips in their phones.
