u-blox Holding AG announced the latest member of its ZOE-M8 series of ultra-small GNSS SiPs. The ZOE-M8B is most power efficient GNSS System-in-Package (SiP) available for small battery powered consumer devices. It combines superior performance with ultra-low power to deliver an optimized solution 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 solution 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. The ZOE-M8B 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.
