Design Method of Wave Transmission Window of Satellite Fairing

Abstract

Satellite fairing with aluminium alloy honeycomb structure has shielding function to radio signal. To receive satellite signal to monitor the satellite status before discarding the fairing, it needs to open a wave transmission window in the fairing. According to the designated orbit of the launch vehicle and the position of station, the α and β angles of measuring line of tracking launch vehicle or satellite are calculated at each time node, and the projective line of the measuring line on the shell is also calculated according to the relative location of the satellite antenna in the fairing. Then the minimum zone can be got which can receive the satellite signal. It realizes the monitoring of the satellite before discarding the satellite fairing, meanwhile, minimizes the infection to the structure strength of the fairing and ensures the safety of the fairing.
