Motorola has created the world's smallest and cheapest chip capable of receiving satellite signals. It will be marketed in the first months of 2003 and seems to be a revolution in GPS systems. And so far the implementation of the GPS system on mobile phones, laptops and similar devices has been difficult and expensive. Now these problems have been overcome: the chip has a size of 49 mm2, half the size of the Pentium 4 chip and will be sold in the fourth part of the price of current GPS systems.
