5.2. GNSS Antenna Interface
5.2.1. General Description
EM05-G includes a fully integrated Global Navigation Satellite System (GNSS) solution that supports
GPS, GLONASS, BeiDou/COMPASS, Galileo and QZSS.
EM05-G supports standard NMEA-0183 protocol, and outputs NMEA sentences at 1 Hz data update rate
via USB interface by default.
By default, EM05-G GNSS engine is switched off. It has to be switched on via AT command. For more
details about GNSS engine technology and configurations, see document [4].
