EM060K-GL&EM120K-GL_Hardware_Design 55 / 78
5.2. GNSS
5.2.1. General Description
The module includes a fully integrated global navigation satellite system solution.
The module supports standard NMEA-0183 protocol, and outputs NMEA sentences at 1 Hz data update
rate via USB interface by default.
By default, the module GNSS engine is switched off. It has to be switched on via AT command. For more
