Multi-GNSS module - L76K - GPS, BeiDou (BDS), GLONASS, QZSS - Waveshare 23721

The L76K GPS module manufactured by Waveshare is a Multi-GNSS module, supports GPS , BeiDou (BDS), GLONASS and QZSS systems and enables precise positioning in conjunction with multiple systems or standalone single-system positioning. It supports the AGNSS function, has a built-in low noise amplifier (LNA) and additional SAW surface acoustic filter for better noise reduction. The module uses the UART serial interface.

Multi-GNSS positioning module - L76K - GPS, BeiDou (BDS), GLONASS, QZSS - Waveshare 23721.

Satellite navigation allows you to determine the position of the tested object.

GNSS is the global navigation system of Global Navigation Satellite Systems, which covers the entire Earth. Its main task is to determine the user's position. The GNSS systems also include the GPS Global Positioning System and GLONASS. Wondering how satellite navigation works? It's simple - as a type of radio navigation, it uses radio waves that are broadcast from artificial satellites to determine the location of points and moving receivers along with the parameters of their movement on the Earth's surface.
