Broadcom Corporation has announced that its BCM47511 solution is powering location awareness in Samsung’s latest smart phone, GALAXY Note.
The Samsung GALAXY Note is one of the first smart phones delivering multiple constellation support to the handset market, by leveraging GPS and GLONASS in addition to Japan’s Quasi-Zenith Satellite System (QZSS) and the Satellite Based Augmentation Systems (SBAS).
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
