GNSS Receiver

4.1. General Description

BG96 includes a fully integrated global navigation satellite system solution that supports Gen8C-Lite of

Qualcomm (GPS, GLONASS, BeiDou/Compass, Galileo and QZSS).

The module supports standard NMEA-0183 protocol, and outputs NMEA sentences at 1Hz data update

rate via USB interface by default.

By default, BG96 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]
