4.3 GNSS
SIM7090G merges GNSS (GPS/GLONASS/BD) satellite and network information to provide a
high-availability solution that offers industry-leading accuracy and performance. This solution performs well,
even in very challenging environmental conditions where conventional GNSS receivers fail, and provides a
platform to enable wireless operators to address both location-based services and emergency mandates.

NOTE
If the antenna is active type, the power should be given by main board because there is no power
supply on the GNSS antenna pad. If the antenna is passive, it is suggested that the external LNA
should be used.
