根據(jù)我們的試驗(yàn),以下幾顆衛(wèi)星比較適合中國HAM的試驗(yàn).
1. RS-12
上行頻道:
145.910 to 145.950 MHz CW/SSB
21.210 to 21.250 MHz CW/SSB
下行頻道:
29.410 to 29.450 MHz CW/SSB
145.910 to 145.950 MHz CW/SSB
信標(biāo)頻率:29.408 MHz
自動聯(lián)絡(luò): Uplink 21.129 MHz Downlink 29.454 MHz
現(xiàn)在這顆衛(wèi)星處在KT模式(21MHz上行,29MHz,145MHz下行)
只需要比較小的上行功率和非定向性天線就可以了.成功率幾乎100%
2.AO-27
上行頻率:145.850 MHz FM
下行頻率:436.792 MHz FM
這是一顆FM方式的衛(wèi)星,根據(jù)試驗(yàn)它的轉(zhuǎn)發(fā)器靈敏度和下行信號
的質(zhì)量都是不錯的,但是最好使用定向天線(2-4單元的八木天線就可以衛(wèi)星跟蹤用的軟件可以在 ftp://ftp.找到,比較好的是 winorbit,軌道參數(shù)可以在nasa或者http://www.找到最新的參數(shù).
