Abstract:

The composition of the electronic control system of the satellite attitude control flywheel(SACF) and the cause of its electromagnetic interference(EMI) on other satellite-carrying equipments were discussed in detail, and a method to reduce or surpress the EMI in the electromagnetic compatibility(EMC) design of the SACF electronic control system was proposed. The effect of suppressing the EMI through EMC design was investigated by EMC tests. The results show that in the proposed EMC design the CE102 conducted interference test met the standard requirement, and different frequency bands were characterized by different margin, the largest was up to 26 dBμV. The RE102 radiation interference vertical polarization test had 7 dBμV/m margin at least, and the horizontal polarization had a greater margin. The design also passed five sensitivity tests of satellite-carrying equipment successfully.

Key words: technology of instrument and meter, satellite equipment, satellite attitude control flywheel(SACF), electromagnetic interference(EMI), electromagnetic compatibility(EMC) design
