In order to cater to the Internet of Things (IoT) and wearable devices markets, semiconductor solutions company Broadcom has launched a new Global Navigation Satellite System (GNSS) chip, known as Broadcom BCM47748. The chip ensures devices such as fitness bands provide pinpoint location.

Power consumption from the new chip is marginal as it handles most of the load associated to signal processing from the device MCU by assessing position, velocity and time (PVT) on-chip. Battery life is increased with the use of intelligent firmware that also preserves accuracy in speed, distance and position, boosting user experience.

Broadcom senior director of wireless connectivity, Prasan Pai, said, “Broadcom is extending its navigation leadership into the IoT ecosystem by helping customers deliver a premium location experience without compromising battery life or requiring a costly, power-hungry host processor. 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.”

Broadcom is currently testing the GNSS chip with customers and is able to provide kits and reference designs. A company executive, Stephen Mole, will provide insight on reducing power consumption in wearables at the Institute of Navigation (ION) GNSS+ 2015 conference at the Tampa Convention Center in Florida from September 14-18, 2015.

OEMs can cut costs and optimise usage of space with the use of chip that absorbs location computations. The chip is also able to adjust to user activity and context due to the presence of firmware, boosting performance despite the existence of power savings.
