Broadcom Corporation (NASDAQ: BRCM) has announced its BCM47511 solution is powering location awareness in Samsung's latest smart phone, GALAXY Note. By using Broadcom's BCM47511 location chip, the GALAXY Note collects signals from four global navigation satellite systems for dramatically increased global positioning speed, accuracy and reliability. The Samsung GALAXY Note is one of the first smart phones delivering multiple constellation support to the handset market. By leveraging the United States NAVSTAR Global Positioning System (GPS), Russia's Globalnaya Navigazionnaya Sputnikovaya Sistema (GLONASS), Japan's Quasi-Zenith Satellite System (QZSS) and the Satellite Based Augmentation Systems (SBAS), users have access to 59 satellites currently 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 GPS and GLONASS assistance data to the device, further enhancing performance and reliability. Product highlights include...
- 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 with Broadcom'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, significantly decreasing system cost, while enabling customization or optimization of GPS/GLONASS navigation software algorithms on the host
- 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 provides GPS Location Library software API's and Assisted GPS (AGPS) protocol client software that gives designers complete access to the BCM47511's advanced positioning capabilities
