Broadcom Positioning Powers Location in Samsung's Latest Smartphone
November 16, 2011
Broadcom Corporation today announced its BCM47511 solution is powering location awareness in Samsung's latest smartphone, GALAXY Note. By using Broadcom's BCM47511 location chip, the GALAXY Note collects signals from four global navigation satellite systems for increased global positioning speed, accuracy, and reliability.
The Samsung GALAXY Note is one of the first smartphones delivering multiple constellation support to the handset market. Receiving signals from GPS, Russia's GLONASS, Japan's Quasi-Zenith Satellite System (QZSS), and the Satellite Based Augmentation Systems (SBAS), users have access to 59 satellites in orbit — nearly twice the coverage of GPS alone.
The additional satellite coverage enables significant improvements in location performance, time-to-first-fix, and accuracy, particularly in urban areas where GPS-only solutions experience reduced signal coverage. Broadcom's Location Based Services (LBS) technology delivers both GPS and GLONASS assistance data to the device, further enhancing performance and reliability.
Product Highlights:
-
The BCM47511 SoC solution is
Broadcom 's latest generation of standalone receivers, featuring both integrated GPS and GLONASS. Since it is pin-for-pin compatible withBroadcom 's popular BCM4751 SoC solution, customers can quickly upgrade their current products to include the benefits of GPS/GLONASS navigation support.- The GPS core of the BCM47511 uses a host-based system architecture that splits processing functions between the GPS chip and the CPU on the host system, decreasing system cost while enabling customization or optimization of GPS/GLONASS navigation software algorithms on the host, Broadcom said.
- The BCM47511 provides low power consumption and an ultra low-power tracking mode.
- The BCM47511 also includes on-chip low drop-out (LDO) regulators to supply the GNSS TCXO and optional low noise amplifier (LNA), reducing overall bill-of-materials (BOM) cost, Broadcom said.

Broadcom providesGPS Location Library software API's and Assisted GPS (AGPS) protocol client software that gives designers complete access to the BCM47511's advanced positioning capabilities.
