Rak1910 GPS Scatter

I have setup two nodes based rak4631/rak19007 with rak1910 ublox max-7q gps.

The scatter in gps readings in my position logs is very large!

Previously, both these nodes were setup using rak gps tracker example firmware connected to a Rak LoraWAN gateway. Very rarely was the scatter outside of a 5m circle when the kits were fixed.

With meshtastic firmware, the scatter in my “mesh maps” and position logs seems to be 5-10 greater!

Can anybody shed light on this?
