Embodiment Construction
[0020] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0021] The invention provides an on-site calibration device of a space-borne induction magnetometer, comprising: a three-dimensional translation support, a magnetic shielding module, a momentless coil and an AC constant current source.
[0022] The three-dimensional translation bracket in the invention is used to support the magnetic shielding device and the momentless coil, and has the functions of lifting and two-dimensional horizontal translation. Move to coincide with the center of the induction magnetometer.
[0023] The magnetic shielding module in the invention can realize a zero magnetic space without interference inside it, and can calibrate the noise index of the induction magnetometer.
[0024] The torqueless coil in the invention is used in conjunction with an AC power source to generate a standard magnetic field with adjustable frequency a...
