RFI


RFI stands for Radio Frequency Interference. It refers to the electromagnetic disturbance that affects the communication or operation of electronic equipment by electromagnetic radiation or conduction. RFI can be caused by natural sources such as lightning, solar flares, and cosmic radiation, or by human-made sources such as power lines, electronic devices, and communication systems. In space and astronautical engineering, RFI can be a critical issue for spacecraft and satellites as they rely on radio communication for telemetry, tracking, and control. RFI can cause signal degradation, data loss, and even complete system failure. Therefore, RFI mitigation techniques such as shielding, filtering, and frequency planning are essential to ensure the reliability and safety of space missions.
