Roger, Stephen, that is right, I asked about ground platforms, not airborne.
Also, I am not asking about triaxial systems. I do not mean measuring the 3C of the total magnetic field, I mean measuring the gradient (or spatial derivative) at a specific site of the total magnetic field. Instead of calculating the vertical gradient or the horizontal gradient with whatever software in the market, I would like to measure it. GEM Systems / TerraPlus offer vertical arrays with the GSM-19. VTEM offers horizontal arrays.
