Pixhawk 4 and Holybro 2nd gen GPS module max position errors

Hardware Pixhawk family
1

Hello,
we are using the Pixhawk 4(Ardupilot 4.0.4) together with 2 Holybro 2nd gen. GPS modules. Can someone tell me what is the “maximum position error” and “maximum position holding error” in connection with the Pixhawk 4 and Holybro 2nd GPS module ?

And what is the relation between this and the “Kalman Filter” ?

The result is for the ConOps / Sora approval process at the LBA Germany.

Thanks in advance.

I would think the only hard data you could use is what’s published by Ublox for the module in those units.
