GNSS click carries Quectel’s L86 GNSS module with a patch antenna along with an external antenna connector. GNSS stands for Global Navigation Satellite System, an umbrella term that describes both the United States GPS and the Russian GLONASS global positioning systems. Excluding its wider applicability, the L86 module is similar to the L80 module (used on GPS3 click). It includes the same set of technologies: automatic prediction of orbits from internally stored data, adaptive adjusting of on/off time to balance between positioning accuracy and power consumption etc. The board uses a 3.3V power supply.
