    I think the signals in high band are ChinaSat 11, or maybe ShenTong-2E testing (see below).


    Although there is no public frequency plan, ChinaSat-11 has transponders in both 11.45...11.7 and 12.25...12.75 GHz bands.

    See for example here (Indonesian): https://www.facebook.com/group…mment_id=1194728690894571

    "The Old transponder on ChinaSat 11 at 98.0°E to one is 12600 v 43200 total channel 45 and the second transponder is 12650 v 43200 as well as 45 channels. In June 2020 the second TP was off due to a disruption to my band's network."

    Probably as so often there are pairs of transponders available of opposite polarisation, so 12600 both in H and V.


    Since August, ChinaSat 11 has moved a bit from 98.0°E to 97.9°E.

    This was to give room for the new ShenTong-2E (ChinaSat-2E), that arrived at 98.0°E (or 98.05°E) also in August.

    Inclination is just 0.2°, probably In-Orbit Testing is still going on.

    At 98.25°E there was already ShenTong-2A (ChinaSat-2A).


    ShenTong are military satellites, presumably using Ku-band but I've never seen any signals reported from this satellite series.

    It's a bit unfortunate that ShenTong satellites are also simply called ChinaSat, suggesting they are from China Satcom with commercial use, but they really are of the PLA (People's Liberation Army).

    This satellite (incl. 0.7°) is now called Eutelsat 12 West E, the former Afghansat 1 / Eutelsat 48D.


    At 12.5°W there is also Eutelsat 12 West F (incl. 4.4°), the former Eutelsat 36A, that has only the 11.7...12.5 GHz band.

    Galaxy 25 (incl. 3.0°) is now co-locating with Galaxy 14 (incl. 0.5°) that arrived at 32.9°E a couple of days ago.

    G-14 has the same C-band frequency plan, though polarisation can be switched to the opposite if needed.

    Intelsat ephemeris says that on 24 August, Galaxy 25 should start to drift East.

    Thanks satesco. I corrected location to 47.7°E.

    Note that these carrier frequencies may not be the centers of actual transponders.

    Probably, very wideband (240 MHz or more) transponders are involved where they uplink test carriers, in a grid 100 MHz apart.

    And if I understood well, the transponder frequency ranges themselves are also flexible.

    Maybe someday, a wideband noise will be uplinked that reveal real transponder bandwidths.

    Express-103 at 96.5°E must have taken over all services of Express-AM33.

    Because according latest TLE, Express-AM33 is moving 1.0°W/day, near 94.5°E now.

    This one stays a mystery!

    I suppose you are sure, it is not 74.9°E ABS-2, that has unspecified Ka-band?

    Since 2019 there is also GSat-11, but that one has only 19.7...20.2 GHz.

    Skynet 4C (incl. 14°) has moved a bit during the last few weeks to about 33.85°E, exact slot to be confirmed.

    Apparently this was done to free the 33.4°E slot for ABS-7 (incl. 1.6°) that just arrived here.

    ABS-7 has both Ku- and Ka-band (C) payload, so probably ABS-7 will do military Ka-band services from here.

    Hello duck77, I knew you can get all these Galaxy's from satellites.co.uk, and let my satellite page end at 100°W for this reason.

    The official footprint seems a bit pessimistic!
