摘要
通过分析目前船载卫通站伺服系统常用的角度调整模式,指出各种角度调整模式均忽略了因地点位置变化及特殊条件下对天线跟踪的影响,提出通过实时计算理论大地角为基础的复合调整模式的设计方案。该方案消除了高俯仰角状态以及地理位置变化对跟踪的影响,解决了过顶跟踪带来的不利因素,使船载卫通设备满足全方位、无盲区跟踪,确保了通信畅通。
Through analysing current adjustment modes of antenna＇s angle of the servo system in shipbome satcom station, this paper points out that all of the modes ignore the influence of position changing and certain cases on antenna tracking. A composite mode in which the adjustment is based on real - time theoretical ground angle is advanced. This mode can avoid some adverse influence of high pitching angle on auto - tracking and overcome the unfavourable factors caused by over- top tracking, keep communication omnidirectional and no blind spot, and ensure unblocked communication.
