MCubed-2 復活

● (No.897) MCubed-2 復活 (2016年1月11日)
　-------------------------------------

米国ミシガン大学の衛星 MCubed-2 が一年半ぶりに復活しているのが、JA0CAW局
により 2016年1月4日に発見されました。その後、管制局によりTLEが再計算され
正確に衛星を追尾できるようになりました。

  MCUBED-2

20:24-20:34JST, 6 Jan 2016, Ele 51 ES-S-WN, 437.479MHz 9600bps GMSK
SDR# -> MixW(COM7) -> Decoder(COM8)  という信号の流れでデコードできます。
公称周波数より低めです。新しい TLE どおりに飛来しました。 10秒毎の送信。

  


How to decode MCubed-2 using MixW

(1) Setup MixW serial port bridge and Device Manager
    http://www.ne.jp/asahi/hamradio/je9pel/mixwbrid.htm

(2) Setup MixW Mode and Configure

    Mode ... Packet
    Mode settings ... Modem, VHF 9600 baud G3RUH
    Mode settings ... General, Check Emulate KISS TNC on TNC emulation port
    Configure ... Sound device settings, Samplerate 22050
    Configure ... TNC emulation, Port COM7*, Baud rate 9600

(3) Install Python 2.7
    http://www.python.org/download/

(4) Install MCubed-2 Decoder
    http://exploration.engin.umich.edu/blog/?page_id=1933

(5) Run setup_pyserial.bat in MCubed-2 folder

(6) Edit run_serial_to_tcp.bat in MCubed-2 folder
    tcp_serial_redirect.py -q -p COM8 -b 9600 --rtscts -P 12500 -i 0 -n JE9PEL

(7) Edit config.props in MCubed-2 folder
    client.callsign=JE9PEL

(8) Run MCubed-2 Decoder in the following order
    1. run_serial_to_tcp.bat
    2. run_gs_client.bat


How to decode MCubed-2 using High-Speed SoundModem(UZ7HO)

設定のポイントは、SoundModem と MCubed-2 Client の "KISS Server Port" を
8100 に合わせ、"run_serial_to_tcp.bat" は使わず、直接 "run_gs_client.bat"
を起動することです。 MixW を設定するよりも、この SoundModem の方が楽です。

(1) Check "Enabled" in "KISS Server Port: 8100"
    HSM(UZ7HO) -> Settings -> Devices -> Server setup

(2) Edit config.props in MCubed-2 folder

    radio.1.name=FCD+SDR#
    radio.1.address=localhost
    radio.1.port=8100
    radio.1.type=KISS
    radio.1.tncport=1
    client.callsign=JE9PEL
    client.id=JE9PEL_GS
    server.address=mxlab.engin.umich.edu
    server.port=12805

(3) Run MCubed-2 Decoder in the following order
    1. Run SDR#
    2. Run HS_SoundModem
    3. Don't use run_serial_to_tcp.bat
    4. Run directly run_gs_client.bat

MXL Ground Station Client update

CADRE, GRIFEX, MCubed-2 の各々衛星に対応する ｢MXL Ground Station Client｣
ソフトが新しく開発されました。詳細な設定手順については、管制局の許可が得
られ次第、JE9PEL/1 が紹介の予定です。(下記)

GRIFEX
21:45-21:57JST, 10 Feb 2016, Ele 52 SE-E-N,  437.480MHz 9600bps GMSK
MCubed-2
17:22-17:33JST, 11 Feb 2016, Ele 60 NE-E-SW, 437.479MHz 9600bps GMSK

    


MXL Ground Station Client setup using "HS-Soundmodem + MCubed-2 Client"
edited by JE9PEL/1, Mineo Wakita

 (1) Access to the following GRIFEX web site.
     http://exploration.engin.umich.edu/blog/?p=2535

 (2) Click "Downloading the MXL Client Application" and open the PDF file.

 (3) Click to get an account at http://mxl-ops.engin.umich.edu/

 (4) Set your account here and Login.

 (5) Input your "Username and Password" in the popuped window.

 (6) Get "API Access Token" number in the bottom right of the display.

 (7) Press "Dounload Public Client Launcher" in "MXL Satellite Client".

 (8) Download automatically "mxl_client.zip" into your PC.

 (9) Extract this zip file to the appropriate folder.

(10) Edit config.props in "groundstation" in "mxl_client" folder.

     > radio.1.port=8100
     > client.callsign=JE9PEL

(11) Run setup_pyserial.bat in "mxl_client" folder.

(12) Don't use run_serial_to_tcp.bat,
     Run directly "run_gs_client.bat" in "mxl_client" folder.

     Rewrite "run_gs_client.bat" as follows.
     > cd groundstation
     > java -jar groundstation_launcher_public.jar

(13) Input your "API Access Token" number in the popup window.

(14) Then run automatically "MXL Ground Station Client v1.1.0".

(15) Change to CADRE or GRIFEX or MCubed2 in "Select Satellite" tab.

(16) Install Python 2.7 at the time of the appropriate timing.
     http://www.python.org/download/

(17) Run HSM (High Speed Soundmodem by UZ7HO).

(18) Check "Enabled" in "KISS Server Port: 8100" in HSM(UZ7HO).
       Settings -> Devices -> Server setup

(19) Then you can decode the signal by the above setting.
