Design and application of measurement and control system used in spacecraft magnetic test based on LabVIEW

To enhance the level of automation and simplify the complicated operations of measurement and control in the spacecraft magnetic test, a new measurement and control system based on LabVIEW software is developed, with consideration of the magnetic test''s process and the available facility. In this system, the power supply and the magnetometer probes can be configured and controlled automatically, the telecontrol of the coil magnetic field can be achieved by one click, and the real-time monitoring of the magnetic field''s fluctuations as well as the sampling & acquisition of the magnetic data are realized. The results of test show that this system has a satisfactory precision, a reliable stability and a high degree of automation. In addition, it is easy to use this sytem.
