Introduction

Standard Precision GNSS Navigation and Positioning Module

The ER-GNSS-M04 series products are multi-system positioning modules for vehicle navigation, portable handheld terminals, and position monitoring markets. ER-GNSS-M04 series products are the fourth generation GNSS navigation and positioning module products, using the low-power anti-interference GNSS SoC chip ER-GNSS-C01, which is fully independent intellectual property rights of Hexincom, with high integration, low power consumption and anti-interference design.

The module supports A-GNSS (auxiliary positioning) function. Improve location speed with auxiliary data services in networked situations. ER-GNSS-M04 series products are divided into ER-GNSS-M04L, ER-GNSS-M04V and ER-GNSS-M04K three model.
