Zida za Satellite ndi Antennas



Mfundo Zake za Satellite Radioelectric Spectrum - Maulendo

Ponena za ma satellites olankhulana, gawo lawailesi yomwe amagwiritsa ntchito likhoza kudziwa chirichonse: mphamvu, mphamvu ndi mtengo. Choncho, tifotokozera mwachidule mitsuko yambiri yomwe imagwiritsidwa ntchito mu satellite. Zomwe zilipo pambaliyi sizomwe zimatchulidwa komanso nkhani zatsopano zikuwonekera tsiku ndi tsiku.

Mipingo Yowonjezera

Wavelengths osiyanasiyana ali ndi katundu wosiyana. Mafunde aatali aatali angayende mtunda wautali ndikumana ndi zopinga. Mafunde aakulu amatha kuzungulira nyumba kapena kudutsa mapiri, koma apamwamba kwambiri (ndipo motero amafupikitsa mawonekedwe a wavelength), mafunde amatha kuima mosavuta.

Pamene maulendo ali pamwamba mokwanira (timayankhula makumi khumi a gigahertz), mafunde akhoza kuimitsidwa ndi zinthu monga masamba kapena mvula, zomwe zimachititsa kuti chinthucho chikhale "rain fade". Kuti tigonjetse chodabwitsa ichi, pali mphamvu yowonjezera, yomwe imatanthawuza mphamvu zowonjezera zowonjezera kapena zowonjezera zowonjezera, zomwe zimapangitsa mtengo wa satana kuwonjezeka.

Kupindula kwa maulendo apamwamba (Ku ndi Ka band) ndiko kulola otumiza uthenga kutumiza zambiri pa mphindi. Ichi ndi chifukwa chakuti nthawi zambiri zimaperekedwa mu gawo lina la mafunde: chigwa, chigwa, chiyambi kapena mapeto. Kudzipereka kwa maulendo apamwamba ndikuti amatha kunyamula zambiri, koma amafunikira mphamvu zambiri kuti asateteze mabotolo, makina akuluakulu komanso zipangizo zamtengo wapatali.

Mwachindunji, magulu omwe amagwiritsidwa ntchito kwambiri pa satelanti ndi awa:
