亞洲四號衛(wèi)星技術資料

1亞洲四號衛(wèi)星技術資料亞洲四號衛(wèi)星根本狀況亞洲四號衛(wèi)星于2003年411日在美國佛羅里達州肯尼迪太空中心成功放射，是美國波音衛(wèi)星系統(tǒng)公司制造的BSS-601HP〔601HP〕功率型三軸穩(wěn)定衛(wèi)星，預期在軌壽命大于16年，在軌精度優(yōu)于±0.05度。亞洲四號衛(wèi)星裝有28C波段轉發(fā)器，帶寬為36MHz55W行波管放大器并配置線裝置，可掩蓋亞洲、澳大利亞、西蘭、獨聯(lián)體等區(qū)域的50多個國家和地區(qū)。亞洲四號衛(wèi)星裝有20個Ku波段轉發(fā)器，共有3個波束，分別為FSS〔固定衛(wèi)星業(yè)務〕中國波束、澳大利亞波束和BSS〔播送衛(wèi)星業(yè)務〕其中中國波束掩蓋中國全境及周邊國家和地區(qū)，初始設置為8個轉發(fā)器；澳大利亞波束掩蓋澳大利亞和香港，初始設置為8個轉發(fā)器，澳大利亞波束是專為澳大利亞設計的可移動成型波束，可依據需要移至其它地區(qū)；BSS〔播送衛(wèi)星業(yè)務〕波束可掩蓋我國香港、華南及臺灣地區(qū)，初始設置為4個轉發(fā)器，該波束將首次為中國局部地區(qū)供給衛(wèi)星直播電視效勞。亞洲四號衛(wèi)星Ku波段中國波束和澳大利亞波束之間可實現(xiàn)信號交鏈，比方由中國波束上行的電路，可以在澳大利亞波束下行；由澳大利亞波束上行的電路，可以在中國波束下行。亞洲四號衛(wèi)星這一獨有的轉換力量，給用戶供給了一個擴大網絡效勞范圍的途徑。亞洲四號衛(wèi)星Ku波段各波束之間可以調動轉發(fā)器。如中國波束轉發(fā)器不敷使用，可從澳大利亞波束調動轉發(fā)器至中國波束，使中國波束擁有的轉發(fā)器數(shù)量最多可達16個。亞洲四號衛(wèi)星Ku波段轉發(fā)器均承受140瓦的行波管放大器，并配備有線或自動增益掌握裝置，是中國上空最高功率的Ku波段轉發(fā)器之一。亞洲四號衛(wèi)星的主要技術參數(shù)如下：亞洲四號衛(wèi)星的主要技術參數(shù)如下：衛(wèi)星制造公司衛(wèi)星型號美國波音衛(wèi)星系統(tǒng)公司BSS-601HP放射時間放射時間投入運行時間運載火箭在軌壽命穩(wěn)定方式軌道位置衛(wèi)星在軌精度2003年4112003年530美國AtlasIIIB大于16三軸穩(wěn)定東經122.2度優(yōu)于±0.05度C波段轉發(fā)器主要技術參數(shù)：衰減轉發(fā)器最大增益變動C波段轉發(fā)器主要技術參數(shù)：衰減轉發(fā)器最大增益變動偏離中心頻率〔MHz〕增益變化〔dB〕轉發(fā)器數(shù)量工作頻率28上行5.845-6.425GHz轉發(fā)器帶寬下行3.620-4.200GHz36MHz上/下行極化方式行波管放大器功率轉發(fā)器特性行波管放大器備份線性雙極化〔水平，垂直〕55帶線3428接收機備份最大有效全向輻射功率〔EIRP最大品質因數(shù)〔G/T〕最靈敏飽和通量密度〔SFD〕飽和通量密度調整范圍信標頻率〕4241.8dBW1.7dB/K-101.2dBW/m2@G/T=1.7dB/K,0dB0-30dB4198.25MHz；4199.25MHz衛(wèi)星轉換頻率2225MHz±120.7±182.6轉發(fā)器最大群時延偏離中心頻率群時延〔MHz〕(ns)02.588.01220.01655.018120.0轉發(fā)器相位噪聲轉發(fā)器相位噪聲衛(wèi)星TWTA特性相對未調制載波的頻偏單邊帶相位噪聲譜密度〔dBc/Hz〕50Hz-71.5100Hz-79.51kHz-94.510kHz-100.01MHz-100.05MHz-100.0輸入回退(dB)輸出回退(dB)00.010.120.430.841.362.784.4106.21511.12016.0亞洲四號衛(wèi)星亞洲四號衛(wèi)星C波段頻率和極化打算亞洲四號衛(wèi)星亞洲四號衛(wèi)星C波段EIRP等值線圖亞洲四號衛(wèi)星亞洲四號衛(wèi)星C波段G/T等值線圖亞洲四號衛(wèi)星C波段EIRPG/T及SFD參考值表城市經度(城市經度(度)緯度(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重慶106.529.641.0-1.6忠縣108.130.241.0-1.5萬州108.330.841.0-1.5巫山109.931.041.1-1.5哈爾濱126.745.840.80.9齊齊哈爾124.047.340.60.4大慶125.046.640.70.7長春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沈陽123.441.841.21.0大連121.639.041.30.6撫順123.841.841.21.1營口122.340.741.30.8鞍山123.041.141.31.0石家莊114.538.041.0-1.1保定115.438.941.0-1.0秦皇島119.639.941.20.1邯鄲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蘇州120.631.341.2-0.8徐州117.134.241.3-0.9連云港119.234.641.3-0.5合肥117.331.941.3-1.1蚌埠117.432.941.3-1.0銅陵117.830.941.3-1.1蕪湖118.431.441.3-1.0安慶117.030.541.3-1.2杭州120.230.341.2-1.0寧波121.629.941.1-1.2舟山122.130.041.0-1.3嘉興120.830.741.2-1.0溫州120.728.041.1-1.3濟南117.036.741.2-0.7東營118.537.441.2-0.3青島120.336.141.3-0.1威海122.137.541.30.5煙臺121.437.541.30.3武漢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重慶黑龍江吉林遼寧河北江蘇安徽浙江山東湖北
