船载卫星遥感数据接收天线跟踪精确度改进方法
|
摘要
针对船载卫星遥感数据接收天线的动态跟踪航行特点,提出一种提高船载卫星遥感数据接收天线跟踪精确度的方法。通过天线伺服控制设计和计算机程序,克服船姿扰动对天线跟踪的影响,实现快速捕获目标卫星并进行精确稳定跟踪,从而解决恶劣海况下,船行过程中对X频段低轨卫星全空域、无盲区跟踪和可视区域内的高精度指向跟踪问题。该方法已在雪龙号船载卫星遥感接收处理系统建设中得到应用,可为后续舰船上建设遥感卫星接收系统提供借鉴。
In marine environment,the vessel shook affects the precision of the fast and accurate capturing and stable tracking of the remote sensing satellite tracking and receiving station in the vessel borne.In this article the light vehicle seat designed by shaft optimization is adopted to improve the dynamic characteristic of antenna system.Through the design of antenna servo control and computer program,the influence of attitude disturbance on antenna tracking.Based on the compound control strategy,the antenna with large scale and the capture satellite signals can be turned fast and stable.The design has been applied in the construction of remote sensing satellite data receiving and processing system of XUELONG,which is the first Chinese large-scale ship borne remote sensing satellite data receiving and processing system.Engineering practice shows that the system design can track the low-orbit satellite of X band in the whole airspace with no blind,also improve the precision of pointing tracking when the vessel move in the poor marine weather environment.The design provides a reference for the subsequent construction of ship borne remote sensing satellite data receiving system.
