4.1. General Description
EG21-G Mini PCIe includes a fully integrated global navigation satellite system solution that supports
Gen8C-Lite of Qualcomm (GPS, GLONASS, BeiDou/Compass, Galileo and QZSS). Additionally, it
supports standard NMEA-0183 protocol, and outputs NMEA sentences at 1Hz data update rate via USB
interface by default.
By default, EG21-G Mini PCIe GNSS engine is switched off. It has to be switched on via AT command.
For more details about GNSS engine technology and configurations, please refer to document [3].
