为实现船用卫星通信天线线极化调整和过顶跟踪的要求,通常采用四轴天线座系统来控制天线。带来的问题是天线座体重量大,控制设备复杂。为提升设备的性价比,设计了AXY天线座系统。这种三轴天线座系统不仅能实现天线天顶无盲区跟踪和实时极化调整功能,还实现了优化系统设计的目标。该AXY天线座非常适合于馈源庞大的前馈线极化船载卫星通信天线系统。2.3 m船用卫星电视单收天线系统就是采用了AXY天线座,航行中天线能实现天顶无盲区跟踪,并且极化调整灵活方便。
Abstract：To meet the requirements for linear polarization adjustment and passing zenith tracking in ship-borne satellite communication antenna,a four-axis antenna pedestal is usually used to control the antenna,leading to the large weight of antenna pedestal and complicated control device. To improve the cost-effectiveness of device,an AXY antenna system is designed. This three-axis antenna pedestal system not only realizes the function of passing zenith tracking without blind zone and real time polarization adjustment,but also realizes the objective of system design optimization. The function of polarization adjustment in AXY antenna pedestal is suitable for feedforward polarization satellite communication antenna with large antenna feeding source. The AXY antenna pedestal has been used in2. 3 m ship-borne antenna for receive-only satellite television. The antenna can realize passing zenith tracking without blind zone and the polarization adjustment is flexible.
