White Paper

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 is ideal for performance driven applications. 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 and has the lowest power consumption, the MAX-M8Q provides best performance for passive and active antennas designs, while the MAX-M8W is optimized for active antennas with best performance. The industry-proven MAX form factor allows easy migration from previous MAX generations. Sophisticated RF-architecture and interference suppression ensure maximum performance even in GNSS-hostile environments. The MAX‑M8 combines a high level of integration capability with flexible connectivity options in a miniature package. This makes MAX‑M8 perfectly suited for industrial applications with strict size and cost requirements. The MAX-M8Q is also halogen free (green) which makes it also a perfect solution for consumer applications. The DDC (I2C compliant) interface provides connectivity and enables synergies with most u‑blox cellular modules. u‑blox M8 modules use GNSS chips qualified according to AEC‑Q100, are manufactured in ISO/TS 16949 certified sites, and fully tested on a system level. Qualification tests are performed as stipulated in the ISO16750 standard: “Road vehicles – Environmental conditions and testing for electrical and electronic equipment”.
