Totogi Fesootaiga Laser

O le Totogi Feso'ota'iga Laser e aofia ai lona maualuga o le fa'aliliuina o fa'amaumauga, tu'uina atu feso'ota'iga vave ma sili atu ona lelei pe a fa'atusatusa i faiga masani RF, fa'apena lelei mo fa'amatalaga fa'amaumauga e pei o fa'ata'ita'iga satelite maualuga ma feso'ota'iga vateatea loloto. O ona foliga saogalemu e mafai ai ona tetee atu i le faʻalavelave poʻo le faʻalavelave, faʻamautinoa o loʻo puipuia pea faʻamatalaga maʻaleʻale. O le mamanu fa'apitoa a le faiga e mafai ai ona fa'afaigofie ona tu'ufa'atasia i va'a va'alele ma satelite o lo'o iai, a'o le maualalo o le eletise e fa'aleleia ai le fa'atinoina o galuega. E le gata i lea, o lona gafatia e tuʻuina atu fesoʻotaʻiga maualuga-bandwidth i luga o mamao mamao e avea ai ma se taʻaloga-sui mo suʻesuʻega avanoa i le lumanaʻi ma fesoʻotaʻiga fesoʻotaiga i le lalolagi atoa.

O le Totogi Feso'ota'iga Laser o se faiga fa'apitoa ua fuafuaina e tu'uina atu ai fa'amatalaga fa'amatalaga maualuga-saosaoa, malupuipuia, ma le umi e fa'aaoga ai laisa leisa. O lenei uta e aofia ai le laser transmitters, receivers, ma masini fesoʻotaʻiga faʻapitoa, lea e galulue faʻatasi e faʻatuina se fesoʻotaʻiga mautu ma maualuga mo fesoʻotaʻiga satelite, suʻesuʻega avanoa, ma talosaga faʻavae. O lo'o fa'aogaina e le faiga fa'atekonolosi leisa infrared e tu'uina atu ai fa'amatalaga i le saoasaoa maualuga pe a fa'atusatusa i faiga fa'afeso'ota'i fa'asalalauga masani (RF), e mafai ai ona fa'aliliuina le tele o fa'amaumauga fa'amaumauga ma sina fa'atuai. O le uta feso'ota'iga leisa ua fa'ainisinia e fa'atautaia le felauaiga sili ona malupuipuia, fa'amautinoa le fa'amaoni o fa'amaumauga ma le tete'e atu i fa'alavelave. O lo'o fa'aalia ai faiga fa'asino ma su'esu'ega maualuga, fa'amautinoaina o lo'o fa'asa'o sa'o le fa'alava leisa i le va o le felauaiga ma le mauaina o iunite, e o'o lava i si'osi'omaga malosi e pei o satelite. Fuafuaina mo misiona i le vateatea, e mafai ona galue i le vevela tele ma tatalia tulaga faigata o le vateatea, maua ai fesoʻotaʻiga faʻalagolago i mamao mamao.
