DM1103

1. SYSTEM OVERVIEW

1.1 General Description

DM1103 is a high-performance mini PCIe-form GNSS module based on Allystar TAU1103 which is with the state-of-the-art Allystar Cynosure III Lite architecture. It has a Full-Mini size and Half-mini size. It supports global civil navigation systems, including GPS, BDS, GLONASS, Galileo, and QZSS. Featured with SAW and LNA, it achieves high positioning accuracy and short TTFF, especially in a harsh urban environment. The standard mini PCIe interface makes these modules easy to integrate into the laptop, industrial PC, and other applications.

1.2 Features

Supports GPS, BDS, Galileo, GLONASS, and QZSS systems Built-in LNA & SAW for better sensitivity Supports A-GNSS Supports geo-fence function Ultra-low power consumption around 13mA in tracking mode Supports antenna supervision
