Leonardo Garberoglio asked 3 months ago

I’m using simpleRTK module, a base station and a rover. I’m connected to rover over USB GPS+pwr port. I’m using kumar ros driver and reading ublox/fix and ublox/nav_hpposllh
My question is, Is there a precision difference between this two messages?
Thank

Hi Leonardo,
I don’t know about ROS, but there is a difference between messages from simpleRTK2B, some messages have an extra digit which provides some extra accuracy. hpposllh is the highest resolution possible.
