俄罗斯发射新的业余卫星
Russia launches new Amateur Radio satellite
A new satellite carrying Amateur Radio 'Yubileiny' (RS-30) was successfully launched from Plesetsk on 23rd May. Radio Amateurs around the world reported receiving the CW beacon signals on 435.315 MHz with reports also of signals on 435.215 MHz At the time of writing it is still not clear exactly which type of transponder, Linear or FM, is onboard the satellite. It appears to be in a 1500 km orbit which would give a pass time of up to 20 minutes and enable stations over 7000 km away to be worked. Work on the satellite started in December 2004 with the intention of launching it in 2007 to commemorate the 50th anniversary of the first satellite Sputnik-1. A full report on the satellite with pictures can be seen at Yubileiny is a next generation small satellite http://www.npopm.com/?cid=242 The Russian Federal Space Agency launch announcement is at http://www.npopm.com/?cid=news&nid=60 Reports on Yubileiny (RS-30) continue to appear on the AMSAT Bulletin Board which you can join at http://www.amsat.org/amsat-new/tools...t/maillist.php A number of Radio Amateurs have posted recordings of the beacon on the web: Henk PA3GUO http://home.vianetworks.nl/users/ham...5_cw_short.mp3 Mineo JE9PEL http://www.ne.jp/asahi/hamradio/je9pel/80525yu2.wav Mark KF6KYI using FT-817ND and Arrow antenna http://brainwagon.org/wp-content/upl...08/05/rs30.mp3 According to Kosmonavtika other satellites on the same launch were Cosmos 2437, Cosmos 2438 and Cosmos 2439 http://www.kosmonavtika.com/lancements/2008/2008.html# Russian Federal Space Agency http://www.npopm.com/

很奇怪,这颗卫星怎么发射前没有一点消息透露? 而且发射后具体参数也没有公布,甚至大家还搞不清楚是Linear还是FM。
不过按照文章上说,这颗卫星轨道高达1500KM,这带来的大覆盖范围倒是一个好消息。

在那個高度, 由於犯阿輪輻射帶的關係, 星上防輻射設施要特別的強, 估計要不是掛在大衛星裡頭, 就是用電子管搞的電路....

由於地球強大的地磁場, 來自太陽的高能帶電粒子, 來到地球上空會受到磁場的法拉地作用, 形成原地轉圈圈的運行軌跡, 這個粒子轉圈圈的地帶由犯阿輪先生預測到, 後來老美發射直上直下衛星, 證實了它的存在, 如果地球沒有磁場, 這些粒子會直接撞入地球, 與大氣產生作用, 會發生電離光及電磁噪訊, 無線電通訊就不可能, 目前只有少量的粒子會逸入地球南北極, 造成極光現象...
犯阿輪輻射帶主要分兩區, 帶正電的質子被陷於從地面起幾百公里以上, 輻射越來越強到 2000-5000 公里最高, 然後另一區主要是負電的電子, 質量小, 被陷於離地面 10000-25000 公里區域 , 由於電子或質子的密度大, 凡帶有電子設備的飛行器, 遇到輻射物撞擊, 就等於接受半導體製程中的高能粒子撞擊一樣, 積體電路會發生錯亂不可回覆, 唯有大電子管的作品不受影響.. |
