Research on the Calibration of Ion Drift Meter aboard CSES

The scientific objective of Ion Drift Meter (IDM) is to measure ion drift velocity, which is perpendicular to the direction of the satellite flight on orbit. IDM calibration includes electronics calibration and plasma environment test. The measurement precision of velocity is validated through testing electronics noise. The velocity measurement range is calibrated by testing the current measurement range. The method and results of gain and temperature drift of electronics circuit testing are introduced. The plasma environment test of IDM has been carried out in INAF-IAPS plasma environment test instrument. The experimental results show that the detector has good performances and will contribute much to the space plasmas parameters monitoring.
