GPS "holes", also in hovering

here the link to the log:

The problem are the “holes” in the gps x and y data, that can also be seen by the jamming and noise indicators in the corresponding graph (the constant descending lines are just a correct data followed by a “zero” some seconds later).

The flight as can be seen in the log is a complete manual hover, no hard manovers in xyz axes, so peaks in the current absortion is not the case.
