Broadcom today announced a new Global Navigation Satellite System (GNSS) chip for Internet of Things (IoT) and wearable devices.

The Broadcom chip enables devices such as fitness bands to deliver pinpoint location while using less power and eliminating the need for a separate MCU in some cases.

Broadcom claims that BCM47748 removes a bulk of the signal processing from the device MCU by calculating position, velocity and time (PVT) on-chip, delivering significant system power savings. The chip uses intelligent firmware to extend battery life while also maintaining accuracy in speed, distance and position for an enhanced user experience.

Broadcom reduces power consumption and lowers costs for original equipment manufacturers (OEMs) by replacing the device MCU and reducing board space.

“With more consumers demanding GNSS in a wider variety of applications, we see a tremendous opportunity to expand our reach into new devices with market-leading GNSS technology,” said Prasan Pai, senior director, Wireless Connectivity Broadcom.
