Výskumný projekt č.1 / KA pásmo :
Referenčné hodnoty zisku G pre paraboly s priemerom od 180 do 450 cm v KA pásme
Astra 3B-23.5°E : Data pakety provajdera Aol ai. v spektre KA pásma od 21,4 do 22 GHz
Autor analyzuje spektrum lineárnych vektorov V+H od 21,4 do 22 GHz a zároveň definuje referenčné
hladiny zisku derivované od prakticky ideálneho stavu kvality (LM=10+ dB pri EIRP=55 dBW) na výstupe
z referenčného radiantu Prodelin 4.5m,pre dátové pakety provajdera AoL ai. v spektre KA pásma
objektu Astra 3B na λ =23.5°vd .Objekt Astra 3B sa hlási na geostacionárnej dráhe pomocou Beacon
identifikátora na fb=20 199 MHz_V podobne ako je tomu pri objekte Astra 4A na λ =4,8° vd,ktorý sa
identifikuje vo zväzku Interconnect/Interactive na Beacon frekvencii fb=19 300 MHz v horizontálnej časti
spektra,čiže nie v aktívne vyťažovanej časti frekvenčného spektra KA pásma okolo f=21,5 GHz.
