亚洲四号卫星技术资料

1亚洲四号卫星技术资料亚洲四号卫星根本状况亚洲四号卫星于2003年411日在美国佛罗里达州肯尼迪太空中心成功放射，是美国波音卫星系统公司制造的BSS-601HP〔601HP〕功率型三轴稳定卫星，预期在轨寿命大于16年，在轨精度优于±0.05度。亚洲四号卫星装有28C波段转发器，带宽为36MHz55W行波管放大器并配置线装置，可掩盖亚洲、澳大利亚、西兰、独联体等区域的50多个国家和地区。亚洲四号卫星装有20个Ku波段转发器，共有3个波束，分别为FSS〔固定卫星业务〕中国波束、澳大利亚波束和BSS〔播送卫星业务〕其中中国波束掩盖中国全境及周边国家和地区，初始设置为8个转发器；澳大利亚波束掩盖澳大利亚和香港，初始设置为8个转发器，澳大利亚波束是专为澳大利亚设计的可移动成型波束，可依据需要移至其它地区；BSS〔播送卫星业务〕波束可掩盖我国香港、华南及台湾地区，初始设置为4个转发器，该波束将首次为中国局部地区供给卫星直播电视效劳。亚洲四号卫星Ku波段中国波束和澳大利亚波束之间可实现信号交链，比方由中国波束上行的电路，可以在澳大利亚波束下行；由澳大利亚波束上行的电路，可以在中国波束下行。亚洲四号卫星这一独有的转换力量，给用户供给了一个扩大网络效劳范围的途径。亚洲四号卫星Ku波段各波束之间可以调动转发器。如中国波束转发器不敷使用，可从澳大利亚波束调动转发器至中国波束，使中国波束拥有的转发器数量最多可达16个。亚洲四号卫星Ku波段转发器均承受140瓦的行波管放大器，并配备有线或自动增益掌握装置，是中国上空最高功率的Ku波段转发器之一。亚洲四号卫星的主要技术参数如下：亚洲四号卫星的主要技术参数如下：卫星制造公司卫星型号美国波音卫星系统公司BSS-601HP放射时间放射时间投入运行时间运载火箭在轨寿命稳定方式轨道位置卫星在轨精度2003年4112003年530美国AtlasIIIB大于16三轴稳定东经122.2度优于±0.05度C波段转发器主要技术参数：衰减转发器最大增益变动C波段转发器主要技术参数：衰减转发器最大增益变动偏离中心频率〔MHz〕增益变化〔dB〕转发器数量工作频率28上行5.845-6.425GHz转发器带宽下行3.620-4.200GHz36MHz上/下行极化方式行波管放大器功率转发器特性行波管放大器备份线性双极化〔水平，垂直〕55带线3428接收机备份最大有效全向辐射功率〔EIRP最大品质因数〔G/T〕最灵敏饱和通量密度〔SFD〕饱和通量密度调整范围信标频率〕4241.8dBW1.7dB/K-101.2dBW/m2@G/T=1.7dB/K,0dB0-30dB4198.25MHz；4199.25MHz卫星转换频率2225MHz±120.7±182.6转发器最大群时延偏离中心频率群时延〔MHz〕(ns)02.588.01220.01655.018120.0转发器相位噪声转发器相位噪声卫星TWTA特性相对未调制载波的频偏单边带相位噪声谱密度〔dBc/Hz〕50Hz-71.5100Hz-79.51kHz-94.510kHz-100.01MHz-100.05MHz-100.0输入回退(dB)输出回退(dB)00.010.120.430.841.362.784.4106.21511.12016.0亚洲四号卫星亚洲四号卫星C波段频率和极化打算亚洲四号卫星亚洲四号卫星C波段EIRP等值线图亚洲四号卫星亚洲四号卫星C波段G/T等值线图亚洲四号卫星C波段EIRPG/T及SFD参考值表城市经度(城市经度(度)纬度(度)EIRPG/T〔dBW〕(dB/K)北京116.439.941.0-0.7上海121.431.141.2-0.9天津117.239.141.1-0.5重庆106.529.641.0-1.6忠县108.130.241.0-1.5万州108.330.841.0-1.5巫山109.931.041.1-1.5哈尔滨126.745.840.80.9齐齐哈尔124.047.340.60.4大庆125.046.640.70.7长春125.443.941.11.1通化125.941.741.21.2延吉129.442.841.10.8吉林126.643.941.01.1沈阳123.441.841.21.0大连121.639.041.30.6抚顺123.841.841.21.1营口122.340.741.30.8鞍山123.041.141.31.0石家庄114.538.041.0-1.1保定115.438.941.0-1.0秦皇岛119.639.941.20.1邯郸114.536.641.1-1.2廊坊116.739.541.0-0.7南京118.832.041.3-0.9南通120.932.041.2-0.7苏州120.631.341.2-0.8徐州117.134.241.3-0.9连云港119.234.641.3-0.5合肥117.331.941.3-1.1蚌埠117.432.941.3-1.0铜陵117.830.941.3-1.1芜湖118.431.441.3-1.0安庆117.030.541.3-1.2杭州120.230.341.2-1.0宁波121.629.941.1-1.2舟山122.130.041.0-1.3嘉兴120.830.741.2-1.0温州120.728.041.1-1.3济南117.036.741.2-0.7东营118.537.441.2-0.3青岛120.336.141.3-0.1威海122.137.541.30.5烟台121.437.541.30.3武汉114.330.641.3-1.4十堰110.832.641.1-1.4襄樊112.232.041.2-1.5宜昌111.430.741.2-1.6重庆黑龙江吉林辽宁河北江苏安徽浙江山东湖北
