"I initially considered a helium blimp, and will likely use one for development of the geophysical receiver system by simply dragging the blimp around by hand on a tether - the slow motion is advantageous for time domain receivers. The problem I see…"
I wish to develop a platform for geophysical work. The problem is that suitable geophysical receivers are copper coils with a weight in excess of 5kg - with ancillary electronics the total payload would likely be 10kg.In addition, an air coil…
