47.7°E Nemesis 1 (P360/PAN)

  • I am not sure for the name (according to our KA list) but I am 100% sure for the position.
    I find it while I tried to get a better signal on 47.5°E satellite.
    I realize there was a weak signal on the analyzer.


    I can't lock with 1.80m but it's there.


    hvdh, you're welcome to confirm the satellite or update my contribution.


    scan @ 47.7°E


    20475 L 4500 2/3 QPSK (not a GS stream)


    there is a 2nd signal at 20600 L

  • As you probably read at Gunter's etc., P360/PAN is a rather "secret" satellite with little info online. Always close to Yahsat 1B at 47.6°, for eavesdropping maybe. You may well be receiving Yahsat instead that also uses the military Ka-band.


    The Satellite Encyclopedia says for P360/PAN: "Has carriers on 20.298, 20.402 & 20.700 GHz."

    Location: Oss, NL, 5.5°E 51.8°N. Rx: Dr.HD F16, TBS 5927.
    Laminas 120cm 1°W...68°E, T-55 9/13/19/23/28/39/42/45°E.

  • OK, thanks hvdh for the details. :73:
    unfortunately, no signal on frequencies mentioned

  • That's good!
    Now that you locked a normal DVB-S, I believe more (but not 100%) in Yahsat 1B.


    P360/PAN is surrounded with so much "secrecy", wouldn't expect anything lockable from it.

  • Impossible.


    This is not Yahsat 1B, I am totally sure, when I am at 47.6°, I can't see the 47.7°E frequencies.


    The satellites are very close but in KA band you need to be perfectly aligned.


    Here is the scan of 47.6°E:


    The first scan of 47.7°E (full band)


    both: you see , the strong signal of 47.5° decrease and is nearly not visible when the antenna is at 47.7°


    Am I wrong ?

  • Amazing, so much difference when turning just 0.2°! :42:


    Yahsat 1B, I'm sure is at 47.6°E nominal.


    The P360/PAN location is quite uncertain, only based on optical amateur observations like all classified satellites. And often just one TLE every 1 or 2 months (last one: 8 July). Unfortunately, I never backed up old TLE's of these satellites.


    But what I do when a new TLE is issued, is check the average longitude around epoch day, round it to the nearest 0.1°, and update that on my sats.htm page. When I look back old in backups of my page of the last 2 years or so, both 47.6°E and 47.7°E are listed about equally.


    So, a lot of uncertainty. Let's hope for more frequent updates during the dark winter months!

    OK, all clear now with your latest informations about TLE update , maybe it is not exactly 47.7°E but it's very close to 47.5°E .

  • Several updates of visual observations, finally
    P360/PAN indeed was observed on 9 September near 47.7°E.
    While Yahsat is at the normal 47.6°E.

  • Finally, today I realized, there are also signals in KA Band A
    between 18300 and 1800 in RHCP and LHCP but nothing found
    (fake scan result)


    any help ?

  • Again the question is, can you still separate Yahsat 1B from P360/PAN ?
    Because according TLE's they are very close right now, both near 47.65°E.
    In the early morning should be better with at least 0.1° separation.


    Yahsat 1B has:
    21 * 54 MHz transponders in band 20.2...21.2 GHz, and
    25 * 110 MHz transponders somewhere in band 17.7...20.2 GHz.
    Signals have been reported in band 19.7...20.2 already but surely more sub-bands are used, for a total bandwidth of 2750 MHz!

  • Well, today I am more confused for this position, this is not Yahsat it's now sure but according to this new lock in the oposite polarisation, I can read a PID Table referring abot47.5°E, but I repeat, this is not Yahsat 47.5°E , I move a little bit to the east to see the Yahsat spectrumand this is not a satellite in inclined orbit., :88:


    47.7°E (?) in LHCP and RHCP, and just to confirm that is not Yahsat , the spectrum in LHCP

  • Nothing really to be confused about, if I understand you correctly?
    P360/PAN is close, but always east of Yahsat as I recall from TLE's.
    And you can separate Yahsat (47.6°E) from P360/PAN (47.7°E).
    Both are not inclined.
    So this 47.5°E mentioned in that table is just a rounded value, not to be taken too literally!
