Future Single-axis gradiometer 2020 is indicated as follows. Gradiometers are the results of advancements in the magnetometry industry consisting of two or multiple sensors. Despite rudimentary magnetometers comprising of a sensor, they record the magnetic field variations in a point instead of measuring the magnetic field.
This method of detection in gradiometers have two major merits:
- Enhancement in the measurement and calculation accuracy
- Reduction in the natural fields of the ground when scanning in an environment, and also recognizing the disturbing noises and signals in the urban environments, facilitating the operation for the operators in finding the actual and unnatural fields
As an illustration, compared to the magnetometers, the gradiometers have less sensitivity to the mineral salts and particles. Accordingly, the operators of this device make fewer mistakes
