Is anyone familiar with frame-dragging of a mass in spacetime?

OpenStudy (anonymous):

Just to further explain, I do know what frame-dragging is, so to speak, I need helping calculating the extra distance a satellite orbiting the earth at 600km would be dragged over one year?

OpenStudy (ybarrap):

I am not at all familiar with frame-dragging or how to calculate it, but I have wondered whether mass has similar feature to electromagnetic fields such as in Faraday's law (induced EMF), eddy currents (induced magnetic fields) or where changing currents induce an EMF in inductors or changing voltages induce currents in capacitors. It seems like gravitational fields should have some sort of induced properties of its own related to gravity and this might be something along those lines, changing gravitational fields inducing something. From the brief intro I've seed on frame-dragging, I don't think this is analogous at all. Does induced frame-dragging have any potential practical applications? Sorry I couldn't help, but this sounds fascinating.
