Are all of the cables the same length?  That includes the cables from
antenna to receiver and the cable carrying the 1PPS from the receiver to
where you are measuring.

And also are you SURE you are measuring the correct end of the pulse, you
want the raising edge.  It is easy to invert the pulse and therefore
measure the falling edge.
