The shipboard three-axis antenna of satellite communication adopts three-axis stabilization and two-axis tracking mode. The reason of opposite polarization interference when using shipboard satellite communication three-axis antenna to track the line polarization satellite is analyzed. The impact of unmatched polarization on communication quality and tracking performance during tracking is also analyzed and a solution is proposed to solve the opposite polarization interference for three-axis antenna. The theory analysis and experiment prove that the scheme is able to eliminate the opposite polarization interference and increase the stabilization and reliability for tracking and communication of three-axis antenna.
