Global Locate, working with Infineon, recently announced to have come up with one of the smallest assisted-GPS (A-GPS) system for mobile phones, with the Hammerhead II single die receiver, which is claimed to be measured only 3.74 mm x 3.59 mm x 0.6 mm.
With the deliverance of such a smallest A-GPS system for cellphones, it seems that the manufacture of GPS satellite navigation chip are fighting to make the smallest GPS chips available for cellphones. The latest A-GPS system is included with LNA, RF Tuner, PLL and baseband works into a standalone die CMOS chip and gives sensitivity to -160dBm, and set fix times as quick as 1s.
The latest A-GPS system has functioned with Philips spin off NXP Semiconductor to roll out a reference design previous week founded the NXP Nexperia cellular system solution 7210 for EDGE/UMTS handsets which is expected to be availed in the Q2. A-GPS makes use of the processing power in the phone for a few of the calculations, developing the chips smaller and cheaper.
