SIM32EA – High-Performance Multi-GNSS L1 Positioning Module (SIMCom)

Product Overview

The SIM32EA is a high-performance multi-GNSS positioning module manufactured by SIMCom Wireless Solutions. It is designed for accurate, low-power satellite positioning in IoT, automotive, industrial, and tracking applications.

The module integrates a high-sensitivity GNSS engine supporting GPS, GLONASS, Galileo, and QZSS, enabling reliable positioning with fast time-to-first-fix (TTFF), strong signal tracking, and improved accuracy in complex environments.

SIMCom describes the SIM32EA as a LCC-packaged GNSS module with AIROHA high-sensitivity navigation engine, capable of simultaneous multi-GNSS reception, delivering high accuracy, fast positioning, and low power consumption. It supports up to 47 GNSS channels, SBAS augmentation, AGPS (EPO/EPOC), and anti-jamming features for enhanced reliability.
