Introduction

The LEA-M8S module delivers concurrent GNSS positioning with high-performance u-blox M8 positioning technology in the industry-proven LEA form factor. With its dual-frequency RF front end, the u-blox M8 concurrent GNSS engine intelligently leverages the maximum number of visible satellites from up to three GNSS systems (GPS/Galileo with GLONASS or BeiDou) for more reliable positioning. The LEA-M8S delivers outstanding performance at low system power consumption and is optimized for cost-sensitive applications. It also supports message integrity protection, geofencing, and spoofing detection.

The LEA-M8S module features a sophisticated RF architecture with jamming suppression to ensure maximum performance even in GNSS-hostile environments. It offers very low power GLONASS capability. As a 6th generation LEA form factor module, it enables easy migration from LEA-6 GPS and LEA-6N GPS/GLONASS modules.

The LEA-M8S module combines a high level of robustness and integration with flexible connectivity options. The DDC (I2C-compliant) interface provides connectivity and creates synergies with most u-blox cellular modules. For RF optimization, the LEA-M8S is equipped with a front-end SAW filter to improve jamming immunity.

The LEA-M8S module uses u-blox GNSS chips qualified to AEC-Q100 and is manufactured at ISO/TS 16949 certified sites. Qualification testing is performed in accordance with ISO16750: "Road vehicles — Environmental conditions and testing for electrical and electronic equipment."

The u-blox LEA-M8S module can also benefit from u-blox AssistNow assistance services. The online service provides GNSS broadcast parameters such as ephemeris, almanac plus time or rough position, which can significantly reduce receiver Time-To-First-Fix and improve acquisition sensitivity. AssistNow Offline data validity is extended to 35 days and AssistNow Autonomous data validity to 3 days, enabling faster signal acquisition after extended power-off periods.
