Introduction

The AT9850 is a high-performance, low-power GNSS dual-frequency multi-constellation satellite navigation receiver SOC, integrating an RF front-end, digital baseband, multi-mode satellite signal processing engine, and power management functions. It features high integration density with a streamlined peripheral application circuit. The chip supports L1 and L5 dual-frequency signal reception, enabling single-constellation or multi-constellation combined positioning across BeiDou, GPS, Galileo, and other satellite navigation systems. It supports China's BeiDou-2 and BeiDou-3 systems, enabling standalone BeiDou positioning and timing.
