    Es'HailSAT-2 26E Primul satelit geostationar pentru radioamatori

    Satelitul geostationar ES'hailsat-2 are la ,,bord,, si transponderul pentru radioamator, lansat de la Centrul Spatial Kennedy in data de 15 Noiembrie 2018 ora 20:46 GMT iar acum este pe orbita geostationara 25.5 Est. Acesta este primul transponder pentru amatori pus in orbita geostationara si se preconizeaza ca arie de acoperire din Brazilia pana in Tailanda .

    Narrowband Linear transponder
    2400.050 - 2400.300 MHz Uplink
    10489.550 - 10489.800 MHz Downlink

    Wideband digital transponder
    2401.500 - 2409.500 MHz Uplink
    10491.000 - 10499.000 MHz Downlink

    Equipment requirements:

    Es'Hail-2 Geostationary P4-A Transponder Frequencies
    EsHail-2 Geostationary P4-A Transponder Frequencies
    X-Band 10 GHz Downlink:
    89 cm dishes in rainy areas at EOC like Brazil or Thailand
    60 cm around coverage peak
    75 cm dishes at peak -2dB
    NB: linear vertical polarisation
    WB: linear horizontal polarisation

    S-Band 2.4 GHz NB-Uplink:
    narrow band modes like SSB, CW
    5W nominal Uplink power (22.5 dBi antenna gain, 75cm dish)
    RHCP polarisation

    S-Band 2.4 GHz WB-Uplink (DATV):
    wide band modes, DVB-S2
    peak EIRP of 53 dBW (2.4m dish and 100W) required
    RHCP polarisation

    Curand Eshail-2 WebSDR https://eshail.batc.org.uk/


    Sursa informatiei : https://amsat-uk.org/satellites/geos...nous/eshail-2/

    Colegii radioamatori din rusia si nu numai dezbat pe forumul de ultrascurte http://forum.vhfdx.ru/sputniki/eshailsat-2/ de ceva vreme variante pentru abrodarea receptiei in 10ghz prin modificarea LNB-urilor pentru satelit .

    Pare greu dar .....este abordabil

    E musai sa ne luam echipamente in 2,4Ghz.... Cu 10Ghz e mai simplu

    Si Nordul ofera puncte, doar orienteaza antena...

    Probabil , o abordare de inceput cum vad eu . Transverter pe 2,4Ghz pentru a face TX catre satelit si parte de RX folosita via WEB-SDR cu delay corespunzator.
