Receiving Qatar Oscar 100 satellite with SDR Console

Le satellite Es'Hail 2 avec transpondeurs radioamateurs

The Es’Hail 2 satellite

The Es’Hail2 satellite is first and foremost a Qatari commercial and geostationary satellite. Here is some information about it: It weighs 3 tons, equipped with an installed power of 15 kW in solar panels and Lithium Ion batteries, it was built by MELCO (Japan’s Mitsubishi Electric Corporation). It was launched on November 15, 2018 from the Kennedy Space Center, Cape Canaveral, Florida by a SpaceX Falcon 9 launcher. The opening to amateur radio traffic was completed on February 12, 2019, two days before the official inauguration of the Phase 4A satellite then named the Qatar Oscar 100 operational satellite.

The satellite transponders

QO-100 fréquences de montées et descentes

The satellite is equipped with two transponders for amateurs:

  • A transponder for narrow-band modes (NB: Narrow band)
  • A transponder for broadband television transmission (WB: Wide band)

The table below specifies the descent frequencies, which will be received for both transponders. You notice that the two transmissions are not made with the same wave polarization.

  9. Bonjour et merci pour ce superbe article que je vais mettre en œuvre.

    Une question reste en suspend:
    quel est le type de connecteur sur la Clé USB de réception TV TNT ?
    C’est pour commander le bon raccord entre la clé et le T-Bias.

    Merci

    Hello and thank you for this great article that I will implement.

    One question is still pending:
    what is the type of connector on the USB stick for DVB-T TV reception?
    This is to order the right connection between the key and the T-Bias.

    Thank you

    1. Merci Stéphane pour l’intérêt porté à mon blog.
      Sur le modèle de clé TNT en photo, il doit s’agir d’un connecteur MCX femelle. Je vous laisse vérifier, cela pourrait varier en fonction du modèle.
      Il existe des adaptateurs, tel celui-ci : MCX mâle / Fiche F femelle ou si vous préférez MCX mâle / Fiche BNC femelle

      Espérant avoir répondu, souhaitant un bon montage de votre station de réception de QO 100 !
      Christian

      Thank you Stéphane for your interest in my blog.
      On the TNT key model in the photo, it must be a female MCX connector. I let you check, it could vary depending on the model.
      There are adapters, such as this one: MCX male / F female plug or if you prefer MCX male / BNC female plug

      Hoping to have answered, wishing a good assembly of the QO 100 receiving station!
      Christian
