Broadcom releases first Global Navigation Satellite system-on-chip

Broadcom Corporation, specialised in semiconductor solutions for wired and wireless communications, announced the launch of the forst first Global Navigation Satellite System (GNSS) system-on-chip (SoC), designed for low-power, mass-market wearable devices such as fitness trackers and smart watches.

The Broadcom BCM4771 GNSS SoC has an on-chip sensor hub, allowing users to  track and manage their health and wellbeing, by delivering precise activity tracking and location data.

The system consumes little power although constantly monitoring user activity levels and location history, in order to improve accuracy. It also features location batching, combining its location capabilities with an integrated sensor hub, contextual awareness, and GNSS.

The solution is complimented by Broadcom's Wireless Internet Connectivity for Embedded Devices (c) Smart and WICED Direct software development kits (SDKs) to provide additional wireless connectivity to the platform.

Broadcom's BCM4771 GNSS SoC is designed in 40 nanometer (nm) process technology, and it includes a sensor hub  that integrates sensor inputs for its on-chip algorithms to detect the user's context,  accurately compute speed and distance traveled, and provide fitness applications with the GNSS track.

The  BCM4771 will be available by the end of Q1 2014.
