GPS on a SIM Card
28 June 2007 by axxxr
A new company called BlueSky Positioning has come up with a complete GPS unit built into a mobile phone SIM card.
Blue Sky Positioning announced it has developed a complete GPS system, including the antenna, which physically fits in, and works from within, a mobile phone SIM slot. GPS receivers have been rapidly shrinking in recent years, but this marks a massive reduction in size as well as the technical feat of receiving GPS satellite signals from a space sandwiched between the phone battery and circuit board. It's A-GPS, so much of the processing is done off the SIM, using data sent over SMS or similar.
The technological advance is considerable; it could certainly deliver the full mapping, location and route-plannin. No software or hardware changes are needed for legacy handsets, it will run under open operating system such as Windows Mobile or Symbian, or on handsets supporting JSR177 (which enables Java applications to talk to the SIM) and switching the SIM will obviously cost a fraction of the cost of a new handset.
Blue Sky Positioning says it is at the prototype stage and is working with SIM manufacturers to start production with samples ready next month. www.blueskypositioning.com source:mbmagazine smartphonethoughts
