5.2. GNSS Antenna Interface

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.
The GNSS engine is switched off by default. It has to be switched on via AT command. For more details
about GNSS engine technology and configurations, see document [5].
