Introduction

Low Power High-performance GNSS Positioning Chip

The ER-GNSS-C01/02 adopts a 28nm process and a smart PMU design that combines ultra-low power consumption and extreme miniaturization to significantly improve the battery life of user devices.

The ER-GNSS-C01/02 is designed for global applications and supports BDS, GPS, GLONALSS, and Galileo for joint positioning of multiple systems. High integration design saves peripherals and on-board area. The ER-GNSS-C01 is a QFN40 package, and the ER-GNSS-C02 is a WLCSP package. Downstream traditional application areas of the BDS, GLONALSS, Galileo, GPS chipset currently mainly include surveying and mapping, deformation monitoring, precision agriculture, etc., while emerging application areas mainly include automotive autonomous driving, drones, outdoor robots, and the Internet of Things (IoT).
