● (No.517) PehuenSat-1 テレメトリ解析 #1(2007年1月17日) ------------------------------------------------------- PehuenSat-1 のボイスとパケットの両方の受信報告が、１月17日の早朝に初めて 日本と台湾の局からありました。下記の他にも、http://www.amsat.org.ar/log.html に多くの報告が記載されています。 Subject: [jamsat-bb:16942] PEHUENSAT-1のボイスダウンリンク From: "Masaji Ishihara JH3BUM" Date: 2007年1月17日 0:02 皆さん、JH3BUM 石原です。 今夜の 22時34分からのパスで PEHUENSAT-1 の音声ダウンリンクを受信しました。 前半にデーターのダウンリンク、後半に音声とデーターです。 西側の低いパスで、信号は弱かったですが、クリアに聞こえました。 スペイン語で LU1YUC と言っているように思いますが、サフィックスが ちょっと聞き取りにくいですね。 MP3 ファイルを以下に置きましたので聞いてみてください。 http://www15.ocn.ne.jp/~masaji/myhobby/hamradio//PEHUENSAT-1/PEHUENSAT-1voice0701161333UTC.mp3 ------------------------------------ Masaji Ishihara 石原正次 JH3BUM 京都 嵯峨野 SAGANO,KYOTO CITY JAPAN AJA #220108 G.LOC PM75UA ------------------------------------ Subject: [amsat-bb:96418] PehuenSat-1 heard and decoded From: "Edward Chuang" Date: 2:29, 17 Jan 2007 Hi all, PehuenSat-1 heard during the pass from 13:25 UTC, Jan.16. I heard female voice messages and packets, I used MixW to decode it, and got the following message: LU1YUC>BEACON>I00,C,F0 (1210 baud): [[M National University of Comahue Research Project PEHUENSAT1 Satellite in orbit since Jan-2007. Please send this full packet to pehuensat@uncoma.edu.ar the next bytes are telemetry data:0011251242927183016162011122 73, Edward / BX1AD Subject: [amsat-bb:96425] PehuenSat-1 telemetry From: "Chuang Edward" Date: 11:17, 17 Jan 2007 A message from Pehuensat team about telemetry decoding: ---------- Forwarded message ---------- Subject: Re: PeheunSat-1 heard and decoded in Taiwan From: Pehuensat To: Edward Chuang Date: 2007/1/17, 6:16 Dear Mr. Edward Chuang, thank you, you were the first one that I listen at the Pehuensat-1 Congratulations, the code is the following one: 001 average mAmp of load of the solar panel 12,5 rechargeable battery 1 12,4 rechargeable battery 2 29 temperature 1 27 temperature 2 18 temperature 3 30 temperature 4 16 temperature 5 16 temperature 6 20 temperature 7 11 alkaline battery 1 2 2 Best regards, Jorge Lassig Subject: [amsat-bb:96475] Peheunsat-1 over West Malaysia From: "Sion Chow Q. C. (9W2QC)" Date: 2:11, 20 Jan 2007 Dear All, This evening (19th January 2007) at 2222 hours Malaysian Standard Time or 1422 hours UTC, I had a 62 degree pass of Peheunsat-1 over West Malaysia. As I was in the shack during the pass, I decided to track this satellite and am pleased to report a successful reception of Peheunsat-1. Below are three voice recordings heard on 145.825 MHz +/-: http://www.9w2qc.net/peheunsat/voice-1.mp3 http://www.9w2qc.net/peheunsat/voice-2.mp3 http://www.9w2qc.net/peheunsat/voice-3.mp3 Unfortunately, the audio level of the 1200 baud packet was too low, and I did not manage to decode anything. I have the complete pass recording in wav format, if it may be of use to anyone. Equipment used were ICOM IC-910H, 10 Element 2M yagi, SSB SP-2000 Preamp. Thank you and have a nice weekend to everyone. 73, Sion Chow Q. C., 9W2QC. Subject: [amsat-bb:96481] Re: Peheunsat-1 over West Malaysia From: "Mike Rupprecht" To: "'Sion Chow Q. C.
