1、四川远教转星调试说明书精四川省农村中小学现代远程教育项目卫星数据接收系统转星调试说明2007年8月关于远教卫星接收系统的转星调试简要说明本次卫星接收的调整，是由于国家广播电影电视总局将远教项目所使用的电视节目以及IP数据资源，由原来的鑫诺1号卫星转播，调整为由亚太6号卫星转播。需要做的调试工作步骤如下：第1步：了解亚太6号卫星的参数转发器号：K4下行频率（单位：MHz）：12395下行极化方式：垂直FEC：3/4符号率（Msps）：27.5第2步：调整卫星接收机参数主要是通过接收机的遥控板或机身面板按钮，进行参数修改，将原来的鑫诺1号卫星的参数，修改成亚太6号卫星的参数并保存（只修改卫星参数）

2、。修改完成后，即可使用它来调整卫星天线。天线调整到能锁定卫星后，使用自动搜索按钮功能，搜索并保存电视节目。第3步：调整卫星天线主要是调整天线的仰角（角度要减小一些，也就是天线现在向着天空要低头一些），方位角（南偏东的角度要增大，也就是天线现在的方向会更偏东方一些）。总的说来，站在天线后方，现在的天线方位要在原来的基础上，向下低头一些，并向左转动一些。各地具体的仰角和方位角参见附表。参看下面的示意图：先松动天线螺丝，然后慢慢摇动天线，最好先确定方位角，再慢慢调整仰角，如此反复，直到出现信号质量或信号电平。天线调整好以后，先固定，再连接好线缆。具体操作如下：调星时连接图如下：通常可由两人一起配合进

3、行调星：首先检查天线与卫星接收机相连接的线缆接头（75-5头）是否完好，再将接收机（需先将卫星参数修改成亚太6号卫星的参数）和一台小电视机按照图示连接好（最好卫星接收机和电视挨着天线，以便及时调整天线），一人轻微、缓慢的上下左右摇动天线（注意动作幅度不要太大，并且要有耐心）；另一人监控卫星接收机上的信号质量或中国教育台电视节目（若无电视机则可直接监控接收机前面板上的“锁定”灯，或“LOCK”灯，灯绿表示信号已经锁定）。信号质量或信号电平达到35%或以上（四川地区通常会在60%以上），即可正常接收视频及数据信号。调星完毕后，必须将天线的螺丝全部拧紧固定，防止风力引起天线方向偏离。另外必须注意，禁

4、止在通电的情况下插拔天线线缆，由于高频头需要接收机或接收卡通过75-5线缆馈电5V，所以带电插拔时有可能会将高频头或接收设备烧毁。第4步：调整卫星接收计算机参数打开计算机，点开卫星接收卡的控制程序，将原来的鑫诺1号卫星的参数，修改成亚太6号卫星的参数并保存（只修改卫星参数）。控制程序锁定卫星后，即可打开IP数据接收软件，进行IP数据资源的接收。注：四川各地的天线角度数，可以在文件后面所附参数表中查询。附 四川卫星接收设施调整参数表序号城市经度纬度亚太6号（东经134度）朝南偏角仰角极化角方位角1成都104.0630.67-48.541.740.1131.52金堂104.3230.88-48.0
