Copter drift in position hold mode

Hi guys,

After I switch stabilize to PosHold mode, the pixhawk copter drift for 1m/s and 10m far away from original position. The I control pitch and roll pull it back, but drift again.

The pixhawk led is green, HDOP value<5.

Can someone help me analysis my problem? Thanks.

NTUN curve looks abnormal, does it relate to I control the pitch and roll?

here attach some curves:
