4.5. GNSS Receiver
EG21-G MINIPCIE integrates a GNSS receiver that supports IZat Gen 8C Lite of Qualcomm (GPS,
GLONASS, BeiDou, Galileo, QZSS). Meanwhile, it supports Qualcomm gpsOneXTRA technology (one
kind of A-GNSS). This technology will download XTRA file from the internet server to enhance the TTFF.
XTRA file contains predicted GPS and GLONASS satellites coordinates and clock biases valid for up to 7
days. It is best if XTRA file is downloaded every 1~2 days. Additionally, EG21-G MINIPCIE can support
standard NMEA-0183 protocol and output NMEA messages with 1Hz via USB NMEA interface.
EG21-G MINIPCIE’s GNSS engine is switched off by default. Customers must switch on it by AT
command. Please refer to document [3] for more details about GNSS engine technology and
configurations. A passive antenna should be used for the GNSS engine.
