4.5. GNSS Receiver
EC25 Mini PCIe 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.
