    1. 详细信息

    APPLICABLE PRODUCT P/NO OR PURCHASE CODE: 19-103G18C-00

     

    1. OVERVIEW

     

    1.1 Description

    §   ST103-18C is a GPS receiver build-in high sense -162dBm chip on board. Based on TECHTOP SOC architecture technology and low power consumption positioning engine, ST103-18C provides excellent sensitivity and short TTFF with no host interaction needed. It is suitable for vehicle products or positioning devices require for high sensitivity and need fast TTFF in weak signal environments with cost sensitive solutions.
