1.  OVERVIEW

 

1.1 Description

§   ST103-25G is a GPS receiver build-in high sense -162dBm chip on board. Based on TECHTOP SOC architecture technology and low power consumption positioning engine, ST103-25G provides excellent sensitivity and short TTFF with no host interaction needed. It is suitable for vehicle products require for high sensitivity and need fast TTFF in weak signal environments with cost sensitive solutions.

 

1.2  GNSS Features

§   SOC architecture technology

§   Support GPS/QZSS/SBAS (WAAS, EGNOS, MSAS, GAGAN)

§   Supports standard NMEA-0183 protocol

§   Built-In Back-up power supply

§   Incorporated TCXO for extreme temperature conditions

§   Incorporated external LNA and SAW filter to realize high-sensitivity and noise immunity

§   Internal Patch ANT Size: 25.0(w)mm×25.0(d)mm×4.0(h)mm

§   RoHS Compliant ( lead-free )
