NEO-M8: u-blox M8 concurrent GNSS modules
■This data sheet describes the NEO-M8 module family which provides concurrent reception of up to 3 GNSS (GPS, Galileo, GLONASS, BeiDou). NEO-M8 is backward compatible with NEO-7, NEO-6 and NEO-5 families.
●Overview:
■The NEO-M8 series of concurrent GNSS modules is built on the high-performing u-blox M8 GNSS engine in the industry- proven NEO form factor.
■The NEO-M8 modules utilize concurrent reception of up to three GNSS systems (GPS/Galileo together with BeiDou or GLONASS), recognize multiple constellations simultaneously and provide outstanding positioning accuracy in scenarios where urban canyon or weak signals are involved. For even better and faster positioning improvement, the NEO-M8 series supports augmentation of QZSS, GAGAN and IMES together with WAAS, EGNOS, and MSAS. The NEO-M8 series also supports message integrity protection, geofencing, and spoofing detection with configurable interface settings to easily fit to customer applications.
■The NEO‑M8M is optimized for cost-sensitive applications, while NEO-M8N and NEO-M8Q provide the best performance. The future-proof NEO-M8N and NEO-M8J include an internal flash that allows future firmware updates. This makes NEO-M8N and NEO-M8J perfectly suited to industrial and automotive applications.
■The I2C-compliant DDC interface provides connectivity and enables synergies with most u‑blox cellular modules. For RF optimization, NEO-M8J, NEO-M8N, and NEO-M8Q feature 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 are 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”.
■The u-blox NEO-M8 modules can also benefit from the u-blox AssistNow assistance service. The Online service provides GNNS broadcast parameters, for example, ephemeris, almanac plus time or rough position to reduce the receiver’s time to first fix significantly and to improve acquisition sensitivity. The extended validity of AssistNow Offline data (up to 35 days) and AssistNow Autonomous data (up to 6 days) provide faster acquisition after a long off time.
