What does any person who might read this think of this posibility?
An electromagnet that is capable of being tuned to the EM frequency of the earth. Could we actually create a magnet to repel against the earth's magnetic field? Since the earth is so massive and the magnetism is so weak, is it possible to change the shape of the magnet to emitt the EM waves in a fashion that spreads it out over a very wide area. Instead of a typical form of propulsion that directs the force into a pinpoint area, this would spread the opposing force over a massive area, but at such a low level that it would not interfere with anything upon the earth.
The most important element of this design would be the element the magnet is made of. It would have to have the ability to be light weight yet highly receptive to the magnetic forces of .3 to .6 gauss.
The difficult part would be precisely creating and sustaining the opposing force. Since it woudl be an opposing force, I think that it would be easier to generate a large area field.
Does this seem like a possibility?

I don't think there's a real problem there, unless you want to move the source of the EM repulsion, (EMR) or have the EM source itself repelled by the Earth's own EM, so it can move itself.
The material would have to be consistent, and able to generate precise EM with well defined properties and known energy/mass ratios.
What you've got in the picture is EM repulsion where EM G, greater than local gravity for the object being lifted. For applied EM repulsion you need to control lift using relative forces to sustain lift, as you say, and to control movement using antigravity.
So
EM G= EMR
EMR= G+ F being the force required
modified by
EM= F +/- direction of applied EM relative to surface.
In effect an EM three dimensional steering wheel, applying consistent repulsion to the object being lifted. Obviously this means retaining a reliable contact between the repelling force and the object. Not easy with current technology, but not at all impossible, theoretically.
Sorry about the equations, but had to improvise.

So what I am seeing is that the EM force would have to compensate for the weight of the object to be lifted along with the antigravity machanisms while giving it spatial stability.
Currently I do not think that we have circutry that has the response time to automatically compensate for the changes in the Earth's EM field, thereby adjusting the levitating platform.
As for the propulsion of the object, how about an ION Drive, small version, attached to at least 4 points with individual movement of 90 deg arc. The ION drive could give the horizontal propulsion and stability while the onboard computer could be in constant monitoring of the EM field.
Again I come back what possible material might have this capability... Maybe carbon nanotubes combined with an ultramagnetic medium that would end up supremely light weight yet highly magnetic?

ION drive can be better regulated, yes. Power/weight ratios are much more easily managed.
I meant local force of gravity, so you could have an automatic adjustment, reacting like a magnet to variations.
Nano is a more appealing form of material, I quite agree. It'd be worth seeing how it can operate in EM fields, too. Nano particles can operate in ways normal materials simply can't. Well worth looking into.

Thinking about it, an ION drive can also work well with EM, same basic physics, so an EM constant isn't out of the question. All you'd need to do is regulate the EM output a bit more.
