Is this, in any way, related to the fact the Earth has a Moon? Ideally, the Earth rotates around the Sun and the Moon rotates around the Earth. However, is it better described as the 'center of mass' of the Earth/Moon rotates around the Sun? Not to mention all those other confounding variables such as other planets and moons?
Also, getting back to the placement of the 'first pps', is there a way to 'sync' the 1 PPS output of an FE-5680A to an external signal, such as a GPS receiver or TBolt? I would think that might be possible given their original purpose. Thanks in advance.

It's caused by the Earth's orbit not being circular and the axis of rotation not being perpendicular to the orbit plane. http://en.wikipedia.org/wiki/Analemma -- These are my opinions, not necessarily my employer's.
