The system of specific equipment is composed of flux, flux induction coil products, car, rail,electric mobile device, mobile device, product manual car position sensor, the measurement and calculation software composition. The main measuring magnetic moment for spacecraft attitude control. It is an object to be measured by measuring in multiple coils uniform across the magnetic flux produced by magnetic measurement system, and then obtain the object to be measured and the core position of the magnetic moment. Methods using the fluxmeasurement instruments corresponding to the magnetic inversion to determine and verify thebasic magnetic parameters of the instrument and equipment flux method.

Through the multi coil flux method moment testing system can be measured quicklyestablished in the dipole quadrupole magnetic model dipole magnetic moment, equivalentquadrupole and core distance and other magnetic parameters. Flux magnetic moment testing system for screening, in satellite development of raw materials and components of solar arraywire layout, space research instruments and equipment of ground simulation assessment set and spacecraft flight control and other aspects of practical significance.

Performance and characteristics:

1) quickly and accurately get the data: the dipole magnetic moment (G10, G11, H11), unit mA*mm2, equivalent quadrupole (G20, G21, H21, G22, H22), unit mA*mm3, core distance(Xm, Ym, Zm), unit of mm.

2) the dipole magnetic moment measurement accuracy of better than 5% + 5mA, M2, corepositioning accuracy is better than 20%.

3) the measuring period of not more than 5 minutes.

4) Mode l 902 flux meter: 5 display units (Maxwell, Maxwell-turns, Gauss, Tesla) to adapt to different functional requirements.

5) the whole test process automation, data acquisition interval in 0.1s ~ 20 s can be adjusted,the least adjustment unit is 0.1s.

6) the stepper motor, precise control, automatic and manual two kinds of modes.

7) software real-time acquisition, data processing, support external program loading in the calculation.

8) devices are made with no magnetic materials or using the shielding measures to guarantee the accuracy of testing.

9) this calculation method without theoretical error, instrument error that exists only measuring instrument of their basic properties.

10) measurement method has the advantages of fast measuring speed, simple measurement process etc..
