Conformity and Certification


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.
