White Paper

LEA-6 modules bring the high performance u‑blox 6 position engine to the industry standard LEA form factor. u‑blox 6 has been designed for low power consumption and low costs, independent of which satellite constellation is used (e.g. GLONASS, Galileo). Intelligent power management is a breakthrough for low-power applications. The versatile, standalone LEA-6 receivers combine an extensive array of features with flexible connectivity options. Their ease of integration results in fast time-to-market for a wide range of automotive and industrial applications. LEA-6 modules work with all available satellite positioning systems: LEA-6H is ready to support the European Galileo system via a simple firmware upgrade; LEA-6N combines full feature GPS performance with the QZSS regional satellite system. LEA-6N also targets the Russian market, featuring the lowest power GLONASS functionality in the industry and is designed for ERA-GLONASS. All LEA-6 modules are manufactured in ISO/TS 16949 certified sites. Each module is tested and inspected during production. The modules are qualified according to ISO 16750 - Environmental conditions and electrical testing for electrical and electronic equipment for road vehicles.
