A Nagy Vezer nagyobb dicsosegere - Kwangmyongsong-3 satellite: a kovetkezo napokban alighanem inditjak az Eszak Koreai raketat, a fedelzeten a nevezett holddal (the “Kwangmyongsong-3″ satellite is scheduled for launch around April 12 to 16th).

"When I saw the first images of the satellite, it reminded me of a Surrey (SSTL)
design from a decade ago. IF placed in a polar orbit, it would have a Western
hemisphere ascension across eastern Brazil, Western Atlantic, and eastern
Canada / Greenland.

Gregory Beat:
"Photos were released today of the Kwangmyongsong-3 satellite, planned to be
launched from North Korea later this week. The rectangular box satellite
appears to have a ~ 400 MHz 1/4 wave antenna on same side as sensors, and
possibly Earth Observation (EO) camera.
I have seen no data on frequencies to be used for EO camera."

Ami radio amator szempontbol erdekes lehet, az a telemetria ill. a "reklam anyag" sugarzasa. Errol ezeket lehet tudni:

"The International Telecommunication Union received notification from North
Korea of its planned satellite launch, the Geneva-based organization confirmed
today (Monday)....
It states the satellite is being launched in “pursuant of the State plan for
space development,” which mirrors last week's official launch announcement.
The satellite will broadcast remote data in the UHF band and video in the
X-band, the ITU quoted the DPRK’s notification as saying
Ill. ezeket:
... AP at the weekend reported the satellite will also play North
Korean revolutionary music. A subsequent MSNBC report said reception
details would be provided at the time of the launch, although I don't
hold out hope for an exact frequency. Last time they said songs were
being played "at 470MHz."
KCNA, April 5, 2009
>>It is sending to the earth the melodies of the immortal revolutionary paeans
>>"Song of General Kim Il Sung" and "Song of General Kim Jong Il" and measured
>>information at 470 MHz.<<
I presume that meant the last satellite was alternating songs and
telemetry on the same frequency.

Tehat a fent idezett tracker oldal alapjan lehet probalkozni a 470 Mz-en, praktikusan egy SDR vevovel.
