Nheyo Dzakawanda dzeSheeri Radioelectric Spectrum - Mafambiro

Kana zvasvika pakukurukurirana kwemasetelliti, chikamu cheredhiyo yevhesi yavanoshandisa ichagadzirisa zvinenge zvose: hurongwa hwemagetsi, simba uye mutengo. Saka, tichaita muchidimbu muchidimbu chemashure makuru maitiro anoshandiswa mumataneti. Mashoko aya anowanika pane izvi haana kunyatsotsanangurwa uye nhau itsva dzinoonekwa zuva rega rega.

Electromagnetic Spectrum - Basic Basic Notions

Frequency Bands

Ivevelengths dzakasiyana dzakasiyana siyana. Marefu evevelengths anogona kufamba rwendo rurefu uye kuyambuka zvipingamupinyi. Marefu evelengths anogona kukomberedza zvivakwa kana kuyambuka makomo, asi akakwirira iyo nguva (uye naizvozvo shoma uwede), nyore nyore mafungu anogona kumira.

Apo mafambiro akareba zvakakwana (isu tinotaura nezve makumi makumi maviri emagigahertz), mafungu anokwanisa kumiswa nezvinhu zvakadai semashizha kana madonhwe emvura, zvichiita kuti chiitiko chinonzi "mvura fade". Kuti akunde izvi zvinoshamisa simba rakawanda rinodikanwa, izvo zvinoreva zvinopfuudza zvine simba kana mamwe antennas akacherechedza, izvo zvinokonzera mutengo we satellite kuti uwedzere.

Kubatsira kwepamusoro-soro (Ku na Ka bands) ndeyekuti vanobvumira vatumira kutumira mamwe mashoko pamusi wechipiri. Ichi ndechokuti ruzivo runowanzoiswa mune imwe chikamu chekuzununguka: chivako, mupata, kutanga kana kuguma. Kuzvipira kwehuwandu hwepamusoro ndeyekuti vanogona kutakura mamwe mashoko, asi vanoda simba rinopfuura rekudzivirira mabhutika, maina antenna makuru uye mari inodhura mari.

Kunyanya, mabhesi anowanzoshandiswa mune sataneti ndeaya:
