CBERS-02B Anti-interference EMC Measures between Subsystems
摘要
Abstract
The article describes that data collection subsystem uplink is interfered during CBERS-2B satellite electromagnetic compatibility test. A series of electromagnetic compatibility measures are carried out.It proved that two star sensors conduct emission and HR camera & WFI camera data transmission radiation emission are weakened during AIT test in all normal working modes (real time imaging and playback mode), so that the data collection subsystem uplink interference is reduced from 15dB to 4dB, and data collection subsystem interference is controlled well. The test proved electromagnetic compatibility measures are available and reasonable. By carrying out these measures, data collection subsystem, attitude and orbit control subsystem as well as HR camera & WFI camera data transmit subsystems are of electromagnetic compatibility.关键词
