a,The second Global Xpress (GX) satellite – Inmarsat-5 F2 (I-5 F2) – launched from the Baikonur Cosmodrome in Kazakhstan, at 12:31 GMT on 1 February 2015.
b,
Once operational, I-5 F2 will deliver Global Xpress services in the Americas and the Atlantic Ocean Region.
c,
The first Global Xpress satellite, I-5 F1, launched in December 2013 and entered commercial service in July 2014, powering regional Global Xpress services for
Europe, the Middle East, Africa and Asia.Following the launch of the third satellite in the Global Xpress constellation (I-5 F3), Inmarsat will progress towards final
global commercial service introduction of GX. Each Inmarsat-5 satellite is expected to have a commercial life of 15 years.

Figure A.4.1 shows the portions of the 27.5-30.0 GHz and 17.7-20.2 GHz bands that can be employed in the Gateway
Beams, the GP Spot Beams, and the HCP Spot Beams, with the spectrum used in the Gateway Beams shown in blue
and the spectrum used by the GP Spot Beams and the HCP Spot Beams shown in yellow. The Gateway Beams operate
in Right Hand Circular Polarization (RHCP) and Left Hand Circular Polarization (LHCP) on both uplink and downlink. The GP
Spot Beams operate in RHCP on the uplink and LHCP on the downlink. The HCP Spot Beams operate in Right Hand
Circular Polarization (RHCP) and Left Hand Circular Polarization (LHCP) on both uplink and downlink.
The Gateway Beams employ state-of-the-art full frequency re-use in their coverage area by means of dual orthogonal
polarization. The GP Spot Beams employ an average six-fold frequency re-use by spatial separation of co-frequency beams
while the HCP Spot Beams reuse spectrum on a co-frequency basis based on spatial separation between co-frequency HCP
Spot Beams as well as between the HCP Spot Beams and the Gateway Beams. In the GP Spot Beams, 72 channels are
available in the forward link direction and 72 are available in the return link direction, each with 40 MHz spacing and 32 MHz
useful bandwidth.These 72 channels in each direction are allocated among the 89 GP Spot Beams, with two channels available
in certain beams. The possible channel to beam allocation configurations in the GP Spot Beams are as shown below.

Inmarsat 5 F2 - 55°W.L. : komentár autora Romana Dávida

Identifikácia a analýza objektu Inmarsat 5-F2 na geostacionárnej dráhe je ďalšou v postupnosti exkluzívnych správ v
európskom kontexte družicového príjmu v KA-pásme,ktoré sú výsledkom výskumnej činnosti autora Romana Dávida .

Kombináciou :
1, výpočtu polohy a zmeny dráhy objektu vychádzajúcich z najnovších dvojriadkových elmentov dráhy TLE,ktoré
vygenerovalo Severoamerické velitelstvo protivzdušnej obrany Norad_Celestrak
INMARSAT 5-F2          
1 40384U 15005A   15161.11740848 -.00000168  00000-0  00000+0 0  9992
2 40384   0.0650 102.9408 0000436 198.3079 338.9686  1.00270594  1312

2, interných údajov od prevádzkovateľa objektu Inmarsat 5-F2 o dvoch presných frekvenciách TT&C _ 19 700,5 a
19 702,5 MHz na ktorých aj momentálne prebieha intenzívna dátová komunikácia tvorená sledovaním okamžitej
polohy objektu,riadením a kontrolingom všetkých vitálnych funkcií sledovaného objektu a pozemným kontrolným
strediskom

3, a autorových vlastných analýz a meraní na výstupe sekundárneho radianta Prodelin 3,7m a 4,5m v spektre od
19,2 do 21,2 GHz,autor dosiahol nespochybnitelnú istotu že aj napriek tomu že prevádzkovateľ objektu Inmarsat 5-F2
(ktorý je v aktívnej prevádzke už viac ako 6 týždňov),stanovil jeho cieľovú pracovnú pozíciu na λ=55°západnej dĺžky,
tento objekt sa momentálne nachádza na pozícii λ=20.2° západnej dĺžky...čo je mimochodom v tomto smere bežná
pracovná traektória väčšiny nových objektov geostacionárnej dráhy pred samotným spustením oficiálnej prevádzky
už na cieľovej/pracovnej pozícii.

Signálne pokrytie objektu Inmarsat 5-F2 cez 89 zväzkov KA-pásma,určené pre oblasti Spojených Štátov Amerických,
Kanady a oblasti atlantiku prakticky vylučuje možnosť príjmu širokopásmových/dvojcestných služieb družicového internetu
pod označením Global Express z tohoto objektu v európskej zóne v súčastnosti ale aj po dosiahnutí cieľovej resp.pracovnej
pozície dráhy na λ=55° zd a môžem vysloviť len nepotvrdený ale vysoko pravdepodobný predpoklad (nakoľko sa jedná
o interné informácie prevádzkovateľa tohoto objektu) o tom že toky dát Telemetrie-diaľkový prenos meraní,sledovnia polohy
a riadenia prichádzajúce z objektu v rozpätí spektra len 200 kHz na dvoch frekvenciách 19 700,5 a 19 702,5 MHz sú
vysielané v globálnom zväzku z dôvodu že dve pozemné riadiace stanice pre prístup do služby Global Express cez objekt
Inmarsat 5-F2/región Atlantiku sa nachádzajú v mestách Lino Lakes v štáte Minesota/USA a Winnipeg/Kanada a nie na
európskom kontinente.
