3D fix Issue in BG96 GNSS Module

[dnsglk]

I have the same issue with my units. It’s always 2D. This thread suggests that if you have GGA with altitude value, it can mean 3D fix. However, it doesn’t seem to be a reliable factor.

On my BG96, GPS fix is always 2D

When using a AT+QGPSLOC=2, I always get a 2D fix. I see the NMEA GGA message and RMC messages are occuring. +QGPSLOC: 004945.0,lat,lon,1.3,1997.0,2,155.40,0.0,0.0,180320,06 Under what circumstances would we get a 3D fix?
