The BCM4750 chip and software package is geared toward wireless personal navigation devices (PNDs) and cell phones.
The receiver can measure faint GPS signals deep indoors and in urban canyon environments at signal levels as low as -162 dBm, Broadcom said. That means it can detect signals that are partially blocked or reflected by buildings or other structures. Rival chips sometimes fail to achieve a location fix or take a long to do so in these environments, said the company.
The receiver also consumes less than 15 mW while navigating with one second map updates. It also enables assisted GPS and long-term orbit, said the company.
As consumer use of location-based services grows, we are seeing an incredible amount of interest from our customers in the cellular and PND markets for GPS and assisted GPS technologies, said Scott Pomerantz, general manager of Broadcom’s GPS line of business, in a statement.
