    The u-blox ZOE-M8Q is designed for wearables, UAVs and asset trackers. Photo: U-blox  U-blox has launched a new positioning module, the ZOE-M8G. The ZOE-M8G is an ultra-compact GNSS receiver module designed for markets where small size, minimal weight and high location precision are essential. ZOE-M8G offers exceptionally high location accuracy by concurrently connecting to GPS, Galileo and either GLONASS or BeiDou. It also provides -167 dBm navigation sensitivity, important for wearable devices, unmanned aerial vehicles (UAVs) and asset tracker applications. The new u-blox ZOE-M8G helps simplify product designs, because it is a fully integrated, complete GNSS solution with built-in SAW-filter and Low Noise Amplifier (LNA). It can be used with passive antennas without the need for additional components, and doesn’t compromise performance. The ZOE-M8G GNSS module measures 4.5 x 4.5 x 1.0 millimeters. Due to its small size, a complete GNSS design using a ZOE-M8G module takes approximately 30 percent less printed circuit board (PCB) area compared to a conventional discrete chip design with a CSP chip GNSS receiver. “When you’re designing products such as smart watches, fitness trackers, asset trackers, UBI dongles and even drones, every square millimeter and every gram counts. The u-blox ZOE-M8G makes it significantly easier for product designers to achieve precise location tracking while keeping within their strict form factor and weight restrictions,” said Uffe Pless, product marketing, Positioning Product Center at u-blox. Samples of the u-blox ZOE-M8G will be available in February 2017, and volume production will start in October 2017.
