CSR allies with Samsung on mobile GPS modules

CSR announced that it has halved the cost of embedded GPS solutions through a collaboration with Samsung Electro-Mechanics Co. The resulting products, based on CSR's GPS software and Samsung's module hardware, are said to bring best in class location-based services to mobile phones, media players and personal navigation devices, while taking the guesswork out of GPS RF design and allowing OEMs a short route to market.

According to ABI Research, the market for GPS enabled handsets alone is set to generate $50 billion in revenues this year, with that figure set to rise to $100 billion by 2012. CSR's software approach eliminates the need for a dedicated GPS baseband; this reduces the cost of the module to less than half of what competitors are able to offer, and offers manufacturers a low cost route to take advantage of this high growth market.

The 9.8mm x 9.8mm x 2.15mm Samsung module is based on the SiGe Semiconductor SE4120S GPS RFIC and is a complete GPS RF subsystem, including voltage regulation, RTC and TCXO, SAW filter and LNA. When combined with CSR's GPS software running on a typical applications processor, the system achieves tracking sensitivity of -159dBm and has a cold start acquisition time of under 40s.

Stuart Strickland, VP of CSR's location business unit said, "Our software architecture already allows the lowest cost design for embedding GPS in high volume applications and we've seen strong interest from tier one mobile handset and consumer electronics companies. By partnering with Samsung, we are now able to completely eliminate a complex, risk-laden and time-consuming step in the product design and integration process, thus making this lower cost alternative available to a much broader range of customers."

Future products will integrate GPS with CSR's technologies for Bluetooth and FM. CSR will be demonstrating its software-based GPS technologies at Mobile World Congress in Barcelona in February.
