GNSS SiP targets small battery powered devices

September 11, 2017 //By Jean-Pierre Joosting
Swiss company, u‑blox has announced the latest member of its ZOE‑M8 series – a power efficient, tiny GNSS System‑in‑Package (SiP) available for small battery powered consumer devices.

It combines superior performance with ultra-low power, making it ideal for portable and wearable devices targeting the fitness, health monitoring, and personal tracker markets.

Small battery powered devices are defined by their limited size, weight and power, which dictates that any GNSS product targeting this application space must provide exceptional performance while consuming minimal system resources. The ZOE‑M8B has been designed for this class of ultra-low-power applications, where size and power are critical parameters. It consumes 25 mW on average in most environments (including urban), and as little as 12 mW during instantaneous tracking. This is a three-fold improvement in power efficiency when compared with other variants in the ZOE‑M8 series.

“The ZOE‑M8B SiP offers the best trade-off between power consumption and location accuracy,” said Uffe Pless, Product Manager Positioning at u-blox. “This will enable manufacturers to develop entirely new battery powered devices that integrate GNSS functionality, without comprising performance or the user experience.”

This combination of ultra-low-power operation and high performance is thanks to the company’s proprietary Super‑E mode of operation, which automatically adjusts the power consumed by the system components based on the external conditions.

The footprint of a design with a chip and individual external components is about 50% larger than the PCB footprint of the ZOE-M8B. Measuring just 4.5- x 4.5- x 1.0-mm, the device integrates a GNSS receiver, TCXO, SAW and LNA in a single package, making it easy to add accurate location and positioning functionality to almost any device.
