The NEO-M8 series of standalone concurrent GNSS modules is built on the exceptional performance of the
u-blox M8 GNSS (GPS, GLONASS, BeiDou, QZSS, SBAS and Galileo-ready
1) engine in the industry proven NEO
form factor.
The NEO-M8 series provides high sensitivity and minimal acquisition times while maintaining low system power.
The NEO-M8M is optimized for cost sensitive applications, while NEO-M8N/M8Q provides best performance and
easier RF integration. The NEO form factor allows easy migration from previous NEO generations. Sophisticated
RF-architecture and interference suppression ensure maximum performance even in GNSS-hostile environments.
The NEO-M8 series combines a high level of robustness and integration capability with flexible connectivity
options. The future-proof NEO-M8N includes an internal Flash that allows simple firmware upgrades for
supporting additional GNSS systems. This makes NEO-M8 perfectly suited to industrial and automotive
applications.
The DDC (I
2C compatible) interface provides connectivity and enables synergies with most u-blox cellular
modules. For RF optimization the NEO-M8N/M8Q features an additional front-end LNA for easier antenna
integration and a front-end SAW filter for increased jamming immunity.
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”.
u-blox’ AssistNow Assistance supply aiding information, such as ephemeris, almanac, rough last position and
time, reduce the time to first fix significantly and improve the acquisition sensitivity. AssistNow data are with
u-blox M8 supporting both GPS and GLONASS constellation for faster acquisition than a GPS-only assistance.
The extended validity of AssistNow Offline data (up to 35 days) and AssistNow Autonomous data (up to 6 days)
provide faster acquisition after long off time.
