Frequency Magnetics (AFMAG) has been used since the 1960\u2019s for geophysical exploration of the subsurface.\u00a0 It relies on passive measurement of \u201csferics\u201d the magnetic pulses that are generated by lightning strikes at a rate of abut 50 per second worldwide.\u00a0 These propagate around the earth trapped between the ground and the ionosphere.\u00a0 \u00a0Locally, these pulses, coming in from different directions, can be used as a convenient source of energy to deduce the electrical conductivity structure of the earth by change in the pulse shape in different directions and at different places.\u00a0 \u00a0Helicopter-towed AFMAG surveys are available from at least two operators and these provide 3D maps of the conductivity structure of the earth to depths of several km.\u00a0 The NovaScan system uses new approaches to miniaturize the equipment to under 4kg, providing a convenient payload for a drone-towed or backpack-portable system capable of mapping at smaller scales with higher resolution to depths of 1km.\u00a0 The low cost and light weight of the system will make it possible to map lithologies and structures at the stage of geological field investigations giving valuable insights early in the exploration program.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column

compartment with the data acquisition system located in the tail.\u00a0 The bird is towed on a lightweight cable below a drone.\u00a0 During flight data from the 3-axis sensor are logged continuously at a rate of 50,000 samples per second.\u00a0 After each sortie, the data are downloaded to a laptop via ethernet using a port at the rear end of the bird.\u00a0 Power for the system is supplied by removable battery packs that can be swapped between flights.<\/p><p style=\"text-align: left;\">In parallel with flight operations, data are collected from a separate 3-axis sensor set located at a fixed location with the sensors pointing in the Cardinal directions.\u00a0 The base station can be unsupervised and can collect data continuously all day.<\/p><p style=\"text-align: left;\">NovaScan software applies well-established techniques for generating transfer functions between related measurements to generate full tensor transfer functions at selected frequencies between 100Hz and 25kHz.\u00a0 At each frequency there are in total 9 transfer functions relating the 3 components measured in flight with the 3 components measured at the base station as well as two transfer functions relating the two horizontal components of the in-flight data with its vertical component.<\/p><p style=\"text-align: left;\">\u00a0<\/p><\/div><p><img loading=\"lazy\" decoding=\"async\"

towed bird and a fixed base station.\u00a0 The bird is about 2m long and it houses the 3-axis sensor assembly in its bulbous leading compartment with the data acquisition system located in the tail.\u00a0 The bird is towed on a lightweight cable below a drone.\u00a0 During flight data from the 3-axis sensor are logged continuously at a rate of 50,000 samples per second.\u00a0 After each sortie, the data are downloaded to a laptop via ethernet using a port at the rear end of the bird.\u00a0 Power for the system is supplied by removable battery packs that can be swapped between flights.\n<br>\nIn parallel with flight operations, data are collected from a separate 3-axis sensor set located at a fixed location with the sensors pointing in the Cardinal directions.\u00a0 The base station can be unsupervised and can collect data continuously all day.\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1a07461 elementor-widget
