    Default Qatar Es'Hail 1 25.5E

    Officials of global space technology and satellites companies have hailed Qatar’s launch of its first satellite Es’hail 1 and the country’s desire to benefit from space technology.
    The satellite was successfully launched into orbit by an Ariane-5 rocket from the European Space Centre in Kourou, French Guiana, on the northeast coast of South America.
    CEO of Es’hailSat, Ali bin Ahmed al-Kuwari, who was present during the launch, said the satellite programme is important for Qatar as the country seeks to meet the rapidly growing communications needs in the region.
    “With the arrival of Es’hail 1, we have completed the first step in our mission to become a centre of excellence in the region and develop a sustainable national satellite industry,” he said.
    “Qatar’s first satellite will provide our strategic stakeholders and commercial customers with broadcasting independence, quality service and wide geographical coverage. We congratulate Arianespace on delivering a picture-perfect lift-off and look forward to working with Eutelsat’s operations team to bring Es’hail 1 into service,” he added.
    The launch event was celebrated by the Qatari delegation. The event was attended by Nicolas Brix, the French minister of foreign trade.
    The Qatari delegation earlier visited the space centre in Kourou, where the necessary procedures and arrangements were being taken prior to the launch of the satellite.
    The launching ceremony was also attended by Qatar’s Minister of Information and Communication Technology HE Dr Hessa Sultan al-Jaber, the CEO of Qatar Foundation for Media Mubarak bin Jaham al-Kuwari, director of Qatar TV Sheikh Abdulaziz bin Thani bin Thani al-Thani and Qatar’s Ambassador to France Mohamed Jaham al-Kuwari.
    Qatar’s delegation included representatives of armed forces, the Ministry of Interior and the Ministry of Communication and Information Technology, Es’hailSat, Qatar News Agency (QNA), Qatar TV, Al Jazeera channel and Al Rayyan TV along with a number of Qatari students and guests.
    Es’hail 1 aims to respond to the needs of local customers in Qatar and throughout the Middle East and North Africa and Central Asia and is to broadcast high definition television (HDTV) and standard definition television (SDTV) channels.
    It will provide advanced satellite services and television, voice, Internet, corporate and government services across the region and beyond.
    The name of the satellite is derived from the name of a star which becomes visible in the night sky in the Middle East when summer turns to autumn.
    “Traditionally, the sighting of Es’hail marks the beginning of the most enjoyable weather conditions in the region and we are eagerly awaiting the launch of Es’hail 1 - our new star over Qatar,” al-Kuwari said earlier.
    Broadcasting from the premium hot spot neighbourhood of 25.5 degrees East and addressing the growing demand for HDTV, Es’hailSat will provide the much-needed additional capacity for TV channels. It will also provide high-tech services for clients in the Middle East and North Africa, and be able to cater to the broadcasting demands of the FIFA World Cup in 2022 which is to be hosted by Qatar.
    Weighing almost six tonnes, Es’hail 1 has four steerable spot beam antennas and four deployable reflectors along with advanced command and telemetry capabilities.
    It is based on the highly reliable SSL 1300 platform and provides the flexibility to support a broad range of applications and technology advances.
    In addition to securing Ku-band continuity and additional Ku-band resources Es’hail 1 will initiate a Ka-band and carries relay payloads in UHF, S-band, C-band and Ku-band.
    Qatar has signed with a partnership agreement to build, launch and operate the satellite with French-based global provider Eutelsat.
    On July, 9 Es’hail marked a major milestone in the satellite programme with the official opening of the company’s capacity management centre (CMC) in Doha.
    Es’hailSat’s CMC will manage access to the company’s satellite fleet, starting with Es’hail 1. The centre is to be manned 24/7 to guarantee and co-ordinate the delivery of high-quality, optimised services to customers with a strong emphasis on interference mitigation and protection of customer signals.

    Eutelsat 25B / Es'hail-1 este deja operational de ceva timp la 25.5°E cu doi transponderi activi:11662 V,27500,3/4 si 12680 H,27500,3/4.N-am avut timp sa urmaresc testele de semnal cind satelitul era pozitionat la 33.7 E.Am incercat sa receptionez acesti transponderi si constat ca semnalul este mic.Cu mare,mare greutate 11680 H mi-a intrat cind semnalul-fluctuant-a ajuns la 17/18 %.Din cauza asta,in loc de nume de programe,imi apar cifre-P689-1005/7/10/12-cu receptorul Strong4500.Semnalul revine constant la 15/16 % calitate,fireste insuficient sa vizionez asa-zisul pachet/program receptionat.
    Am scanat satelitul cu utilitarul Crazyscan,si cu toate ca curba semnalului la cei doi transponderi activi pare promitatoare,dar in fapt nu se poate inchide semnalul pe nicio polaritate.Daca ma uit la footprintul satelitului-spot Mena pe zona mea constat ca e imposibil sa am semnal util.As zice ca e un accident{si este!} faptul ca vad semnal pe bara,iar pe moment mi-a si dat iluzia ca e posibil sa receptionez satelitul cu antena de 1.5m,cel putin spotul MENA.
    Vreau sa stiu daca receptionati acest satelit si ce semnal aveti cu tunerele voastre?

    Semnal si pe 11662 V si pe 11680 H. Pe primul gaseste 20 programe (Alsirat Tv, Bahrain TV, BBC Persia ,OTV,etc) , pe al doilea TP 13 programe (CBC, CIMA, LDC, SonLife, Top Movies, Tunisna, etc) . Alien2+ nu arata semnalul in db ci in procente, dar ca idee: pe 11662 V am SNR 55%, AGC 72%, BER 720 (imagine buna, fara probleme) , iar pe 11680 H SNR 45%, AGC 72%, BER 4200 (foarte mare, de unde si mici probleme pe imagine). Se pare ca si de data aceasta in SE suntem avantajati. O seara frumosa!

    Am gasit un transponder de Data-11172 H,4223,3/4,Dvb-S2-cu semnal destul de tare daca tinem seama ca footprintul este Mena.Semnalul pe transponderii cu pachete,de la 11600-11700 MHz,sta in jur de 3-4dB.Citeodata el creste incit s-a intimplat odata sa inchid semnalul cu receptorul la 11604 H,27500,3/4.Desigur fara sa am imagine.
    Poate alti pasionati din zona mea sa aiba mai mult noroc!Cu antena putin mai mare decit a mea,de 1.50 m,si bine reglata au sanse sa receptioneze mai mult decit am reusit eu.Le doresc noroc si-i astept sa posteze rezultatele aici,pe forum.

    Un post scriptum fericit;in timp ce postam constatarile pripite de mai sus,iata ca am fost dezmintit pe loc in timp ce am facut o ultima scanare inainte de a muta antena.Si surpriza este de proportii,semnalul pe doi transponderi a putut fi inchis si scanati:11565 H si 11605 H.Rezultatul il vedeti mai jos.Mentionez ca vremea a fost buna,senina si temperatura de 10˚C la Cluj-Napoca.

    Deci pana la urma ce dimensiune trebuie sa fie antena pentru acest satelit ? Locatie: Bucuresti . Nu de aia dar mi-am comandat receiverul Humax cu Irdeto2 al celor de la Bein Sports Arabia si vreau sa stiu ce trebuie sa fac. Eu am o antena de 1,9 AL , este suficient ? Sau sa investesc intr-una de 2,1 AL ?

    Daca receptorul Humax are un tuner cat de cat sensibil, receptia ar trebui sa fie ok pe antena de 1.9m. Pentru Bucuresti receptia la 25.5E pleaca de la o antena cu diametrul 1.4-1.5m (poate chiar mai mica daca antena este performanta). Deci cu antena 1.9m si un LNB bun trebuie sa fie ok, daca antena nu este lovita, stramba, etc..
