Receiving Qatar Oscar 100 satellite with SDR Console

Pointer sa parabole satellite vers Qatar Oscar 100

To determine the position of its antenna, it must be pointed as precisely as possible towards the geostationary satellite, positioned at 26.0 degrees East, overhead Kisangani, 35,800 kilometres above the Democratic Republic of the Congo. To help you, you will find below some software on PC, or on smartphone that will help you to do this.

Another solution is to get help from the sun. This web page (french), or this page (french), will tell you at what time the sun is exactly in the direction of the satellite. At this time, you will try to center the shadow of the feed on the vertical axis of symmetry of the dish. You can also help yourself by placing a cord between the bracket and the top of the parabola. Now all you have to do is adjust the elevation, searching directly on your SDR receiver for the strongest signal levels

The third adjustment consists in rotating the LNB unit on itself according to the value of the skew angle.

Online software to help with pointing

After indicating your location, and the desired satellite, these websites provide information on the azimuth, elevation and skew angle to be adopted to point the satellite.

Software for mobile phones

If you are equipped with a smartphone, you may be helped by software that calculates the antenna direction according to your position, and even allows you to display on the screen, the theoretical position of the satellite in the sky in superimposition of the real vision taken by the camera/video of your smartphone. A good way to check that you do not have a direct obstacle that obstructs the reception of signals.

  4. Bonsoir,
    super papier et bravo pour ceux qui n’avaient pas encore installé la “synchro” !!! attention à une chose, le décalage de la tête …qui n’est pas le même pour tous ! pour ma part je dois rentrer 9.749.852 pour pouvoir avoir le bon calage… 73 Maurice F6CIU

    Hello,
    great paper and well done for those who have not yet installed the “synchro” !!!! watch out for one thing, the head shift…which is not the same for everyone ! for my part I have to go in 9,749,852 to get the right adjustment…. 73 Maurice F6CIU

  5. Bravo pour tout ce travail de défricheur de solutions qui se révèlent extrêmement performantes et la clarté du propos, particulièrement précis pour l’installation des composants tant matériels que logiciels. F6CNG Olivier

  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!

  11. Bonjour,
    Tout d’abord un énorme merci pour la mise à disposition de ces informations.
    Concernant l’orientation de la parabole, je ne trouve pas le satellite QO100 dans les liens que vous indiquez. Mais peut-être puis-je prendre un satellite positionné à 26° Est (tel que ARABSAT…).
    Encore merci

    (Translation)
    Hello,
    First of all, a huge thank you for making this information available.
    Regarding the orientation of the dish, I can’t find the QO100 satellite in the links you indicate. But perhaps I can take a satellite positioned at 26° East (such as ARABSAT…).
    Thank you again

    1. Merci Alain pour les remarques.

      Il est vrai que Es’hail 2 (QO100) est situé plutôt proche d’ARABSAT (en réalité composé de 4 satellites BADR 4, 5, 6 et 7 placés entre 25,98° et 26,02° Est). QO100 est précisément à 25,76 ° Est. Il est donc à environ 176 km des satellites ARABSAT sur l’orbite géostationnaire (~ 35794 km d’altitude).

      Thank you Alain for the comments.

      It is true that Es’hail 2 (QO100) is located relatively close to ARABSAT (in fact composed of 4 BADR satellites 4, 5, 6 and 7 located between 25.98° and 26.02° East). QO100 is precisely at 25.76° East. It is about 176 km from the ARABSAT satellites in geostationary orbit (~35794 km altitude).
