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.
