摘要： An airborne ElectroMagnetic (EM) survey system wherein the system includes; first, a series of transmitter coils, which induce a primary (EM) field into the earth resulting in a secondary EM field being created in any sub-surface electrically conductive bodies; and second, a set of three orthogonal receiver coils which detect the secondary EM field. Multiple transmitter coils through which an electric current is pumped, form part of the structural, aluminum framework of a multi-rotor drone. The receiver sensor may be an EM induction sensor, comprised of multi-turn, copper windings, mounted inside an aerodynamic bird and separated by non-conductive sphalerite, which acts as an electrical insulator to limit self-induction and capacitance.Additionally a lighter-than-air balloon may be used to add vertical lift and increase a pendulum effect.

摘要： A system for tracking a drill bit. The system uses a self-propelled autonomous receiver. The receiver has an antenna assembly, a processor, and a propulsion system. The antenna assembly detects the magnetic field from an underground transmitter and generates an antenna signal. The processor is programmed to receive the antenna signal and generate a command signal. The propulsion system receives the command signal and moves the receiver to a position above the transmitter. Once in the desired position, the antenna assembly measures the magnetic field to determine the location of the drill bit along borepath.

摘要： The present invention provides an airborne electromagnetic receiver having a large dimension to allow low transmitter base frequency. A modular and configurable suspension assembly is provided for use within a receiver support structure and suspending the support structure. The suspension assembly has a rigid support having a suspension portion, and links connecting the suspension portion and the suspended structure. The links are adjustable in length and tension to radially suspend said equipment support structure. The natural frequency of the suspension assembly and the suspended receiver motion can be optimized by adjusting mass distribution, suspension link length and suspension link tension. The suspension assembly can be used to suspend a receiver having large receiver coils. The suspension assembly converts high frequency vibration forces imparted on the receiver to a low frequency oscillation. The suspension assembly may also be tuned to avoid coincidence with the excitation frequencies.

摘要： The present invention relates to a HTEM system that includes a semi-rigid bucking coil and an algorithm to determine the magnetic field B from the measured signal dB/dt. The bucking coil may be positioned in a concentric coplanar manner relative to a transmitter coil and receiver coil, in order to minimize spurious signals at the receiver coil during data acquisition time. Signals gathered by the system may be further processed by a signal processing means. Moreover, measurements performed upon data generated by the system may be performed upon the entire period of a current waveform applied to the transmitter and bucking coils.

摘要： An airborne electromagnetic survey system for conducting geological mapping is disclosed. A transmitter closed loop structure is used in the system and is designed for connection to a towing airborne vehicle. The transmitter loop structure comprises a plurality of interconnected loop segments, and transmitting means are fitted to at least one of the loop segments for generating and transmitting an earthbound primary electromagnetic field effective for geological surveying. Sensing means are fitted to the loop segments for receiving and sensing a vertical component of a secondary resulting electromagnetic field which arises from an interaction of the primary electromagnetic field with ground bodies that are traversed by the sensing means, while simultaneously nulling the primary electromagnetic field. Helical sensing means are positioned in close proximity to the transmitting means to receive and sense a horizontal electromagnetic field contained in the secondary resulting field, while simultaneously nulling the primary electromagnetic field.
