Original L76K Multi-GNSS Module – PartsCountry

Description

The?L76K GPS Module?is a Multi-GNSS (Global Navigation Satellite System) module. It can acquire and track any mix of 3 multiple satellite constellations, providing simultaneous GPS, GLONASS, BeiDou, Galileo and QZSS open service L1 reception capability. This increases the number of visible satellites and reduces time-to-first-fix, allowing accurate navigation in settings such as urban canyons.?

The module also has AGNSS (Assisted GNSS) to significantly improve the start-up performance by providing the necessary data to the device via a radio network instead of the slow satellite link, essentially “warming up” the receiver for a fix, a low-noise amplifier for improved reception sensitivity, a SAW filter for enhanced noise reduction performance, and online resources and a manual for ease of use.?

It’s also compatible with multiple platforms including Raspberry Pi, Pico, Arduino, ESP32 and STM32.

Note: The Raspberry Pi is NOT included
