Abstract
An airborne time domain electromagnetic survey system is provided. The system and apparatus of the present invention are able to address the interest in exploring base metals and uranium deposits at depths approaching 1 kilometer. It encompasses a transmitter coil having a large magnetic dipole moment, flight stability, which is light weight, compatible with small helicopters, and can be transported, setup and repaired in the field. It is of a semi-rigid modular structure that can decrease the incidence of damage or breakage during take-off or landing in rough terrain.
Claims8
An airborne time domain electromagnetic surveying transmitter coil assembly, comprising:
- (a) a transmitter section including
- (ii) a transmitter coil;
- and
- (iii) a semi-rigid modular polygonal transmitter coil frame supporting the transmitter coil, the transmitter coil frame having straight frame sections that are joined at corners of the transmitter coil frame by, joints permitting the straight frame sections to at least partially rotate about long axes thereof enabling the shape of the transmitter coil frame to adjust during landing contact with a ground surface to reduce stress on transmitter coil frame;
- and
- (b) a suspension assembly for towing the transmitter coil frame behind an aircraft, the suspension assembly supporting the transmitter coil frame at a plurality of spaced apart locations.
