摘要
介绍国内两种车载同步轨道卫星移动通信系统。一种是相控阵天线跟踪的UHF频段卫星移动通信系统。另一种是采用激光陀螺跟踪的Ku频段宽带卫星移动通信系统,它综合应用了航天遥测、激光陀螺、GPS定位和Ku频段数字卫星通信等技术,在国内首次实现了话音、传真、数据和图像宽带大容量动中不间断通信。
Two kinds of vehicle synchronous orbiting satellite mobile communication systems are introduced. One is phased array antenna tracking UHF satellite mobile communication system; the other is laser gyro tracking Ku broadband satellite mobile communication system. Combining telemetry, laser gyro, GPS orientation and Ku frequency range digital satellite communication techniques, the second system has realized the uninterrupted communication of sound, fax, data and images in the way of broadband, big volume and movement in our country for the first time.
