Hi, which of these solutions have better accuracy for positioning? and why? do you have any recommended document? thanks

Hi,
Please refer to chapter 2.6 “Dead Reckoning Function” of the hardware documentation for the introduction of the DR function.

Best Regards

Hi, but that document does not mention the accuracy of DR vs GNSS

Hi，

Yes, the document does not currently reflect specific data, because many scenarios are changeable and it is difficult to give a specific value. But from the actual test, DR will improve the accuracy of GNSS, especially in multipath environments or tunnels without GNSS.

Best Regards
