Hello,

my goal is to achieve 1cm accuracy with GPS-RTK.

This kit: SparkFun GPS-RTK Dead Reckoning Kit (SMA) SparkFun GPS-RTK Dead Reckoning Kit (SMA) - KIT-23452 - SparkFun Electronics has in description: “~0.2-meter accuracy” (which is not cm level accuracy at all)
This board (from the kit I suppose): SparkFun GPS-RTK Dead Reckoning Breakout - ZED-F9R, SMA (Qwiic) SparkFun GPS-RTK Dead Reckoning Breakout - ZED-F9R, SMA (Qwiic) - GPS-22660 - SparkFun Electronics has in description: “~0.01 meter accuracy”

Why the accuracy difference? Its because of the antenna?
Thanks.

I think it is a typo that meant to say accuracy = 0.2 degrees; we’ll get it fixed!
