Two Piece Chipset for GPS Makes a Four Chip GPS Receiver

Philip Mattos

Abstract:	A 32-bit CPU integrated with both 12 channel dsp hardware and on-chip peripherals (UARTS,parallel I/O, realtime clock) and a matching single chip radio, using a 5Oppm crystal rather than expensive TCXO, make the core of the receiver. Add RAM and ROM together with sophisticated software available under licence yields a 4 chip receiver with components parts under $50 in volume( 1 OOk +), but with acquisition times second to none and only software differences between the oem car model and the centimetre-accurate survey version, and the ability to load user software onto the same CPU makes higher levels of system integration even more cost-effective.
