L76K Multi-GNSS Module, Supports GPS, BDS, QZSS

The L76K GPS Module is a Multi-GNSS (Global Navigation Satellite System) module, supports GPS, BeiDou (BDS), GLONASS and QZSS systems, allows multi-system combined or single-system independent positioning. Supports AGNSS function, built-in low-noise amplifier and sound surface filter, provides a good positioning experience of fast, accurate, high-performance.

Features: 

• Supports Multi-GNSS systems: GPS, BeiDou (BDS), GLONASS and QZSS
• Built-in Low-Noise Amplifier (LNA) for improved reception sensitivity
• Built-in SAW Filter for enhanced noise reduction performance
