BlueSky Positioning looks to have taken advantage of the altogether too cleverly-named SIMposium conference to trot out what is surely its biggest product to date: a complete GPS system embedded on a SIM card
, The Register reports. Partly responsible for that shrinkage is the use of Assisted GPS
(or A-GPS) instead of standard GPS, although they still had to contend with some serious power consumption challenges and the small matter of actually getting a signal. That was apparently accomplished by using the cellphone itself as a makeshift antenna, which supposedly provides just enough of a signal when the SIM card comes into contact with it. While its seems to have gotten the size right, BlueSky's SIM card does currently fall short in a few fey areas, failing to pass ISO tests for flexibility and robustness. That doesn't seem to be holding 'em back, however, with the first production samples reportedly on track for June.
