u-blox M8 concurrent GNSS modules

Compact u-blox M8 concurrent GNSS modules
The MAX-M8 series of standalone concurrent GNSS modules is built on the exceptional performance of the u-blox M8 engine in the industry proven MAX form factor. With dual-frequency RF front-end, the u-blox M8 concurrent GNSS engine is able to intelligently use the highest amount of visible satellites from two GNSS (GPS, GLONASS and BeiDOU) systems for more reliable positioning.

The MAX-M8 series provides high sensitivity and minimal acquisition times while maintaining low system power. The MAX-M8C is optimized for cost sensitive applications, while MAX-M8Q/W provide best performance and easier RF integration.
