I-Satellites ingemva kwalolu suku lwangomhla
I-Global Positioning System (i-GPS) imangalisa yezobugcisa eyenziwe yile iqela lama-satellites ekujikelezeni komhlaba. Ihambisa iimpawu ezichanekileyo, ivumela abafumana i-GPS ukuba babale kwaye babonise indawo echanekileyo, isivinini, kunye nexesha kumsebenzisi. I-GPS ilawulwa yi-US
Ngokubamba iimpawu ezivela kuma-satellites, abalamkeli be-GPS banako ukusebenzisa umgaqo wemathematika wokuqhawula indawo. Ngokudibanisa kwamakhompyutha kunye nedatha egcinwe kwimemori efana neemephu zendlela, amaphulo anomdla, ulwazi lwezobugcisa, kunye nokunye okuninzi, abafumene i-GPS banako ukuguqula indawo, isantya, kunye nexesha lolwazi kwifomati yokubonisa.
Invention kunye nokuguquka kweGPS
I-GPS yenziwe ngokusekwa yiSebe lase-United States loKhuselo (iDOD) njengesicelo somkhosi. Inkqubo iye yasebenza ukususela ekuqaleni kwee-1980 kodwa yaqala ukuba yinto encedo kubantu abahlali ngasekupheleni kweminyaka yama-1990 kunye nokufika kwezixhobo zabathengi ezixhasa. I-GPS yabathengi sele ibe yimboni yeebhiliyoni eziligidigidi kunye neentlobo ezininzi zeemveliso, iinkonzo, kunye neenkonzo ezisekelwe kwi-intanethi. Njengoko iteknoloji, uphuhliso lwayo luqhubekayo; ngelixa liyimimangaliso yanamhlanje, iinjineli ziyabona ukulinganiselwa kwayo kunye nomsebenzi ngokuqhubekayo ukunqoba.
I-GPS Amandla
- I-GPS isebenza ngokuchanekileyo kuzo zonke izimo zemozulu, malunga newashi, kunye nehlabathi lonke.
- Akukho mrhumo wokubhaliselwa ukusebenzisa ii-GPS.
- Abamkeli be-GPS ngokubanzi bachanekileyo ngaphakathi kweemitha ezili-15, kwaye imimodeli emitsha esisebenzisa iMpawu yokuNyuselwa kweNdawo yeNdawo yeeNdawo (WAAS) zichanekileyo zingakapheli ezintathu.
Iimiqathango zeGPS
- Iimpawu ze-GPS zingavalwa ngamahlathi amakhulu, iindonga ze-canyon, izakhiwo zendawo, izibhanti, iindonga kunye nezinye izinto, ukwenza ukuhamba kwe-GPS echanekileyo kunzima okanye akunakwenzeka.
- Ngokufanayo, i-GPS ayisebenzi kakuhle kwiindawo zangaphakathi nangaphantsi komhlaba.
- Ukugcinwa kwethempyutheni, ukuphazamiseka kwomsakazo kunye neziphepho zelanga zingabangela ukuba kubekho izikhalazo.
Umzamo wamazwe ngamazwe
I-GPS ene-US kunye ne-operated GPS yinkqubo ye-navigation-based satellite-based-based network, kodwa i-constellation yaseRussia ye-GLONASS inikezela ngenkonzo yehlabathi. Amanye amadivaysi e-GPS abasebenzisi abasebenzisi basebenzisa zombini iinkqubo ukuphucula ukuchaneka kunye nokwandisa amathuba okufumana idatha efanelekileyo yendawo.
Amazwi anomdla malunga neGPS
Ukusebenza kwe-GPS kuyimfihlelo kubantu abaninzi abasebenzisa yonke imihla. Ezi zinto zinokumangalisa:
- I-GPS ye-Military isebenzisa ii-frequencies ezimbini, ngelixa i-civil isebenzisa enye kuphela. Oku kwandisa ukuchaneka. Iifowuni ze-GPS eziqhelekileyo ziyafumaneka kubahlali, kodwa iindleko kunye nobukhulu benza ukuba kube nzima.
- Urhulumente waseUnited States usebenza kwinkqubo yokuphucula kunye neyenzi-ntanethi yezigidi ezininzi.
- Abahlawuli berhafu base-US baxhaswa ngeenkonzo ze-GPS zehlabathi, ngokubanzi kwiSebe lezoKhuseleko. Uhlahlo lwabiwo-mali lwama-2017 lwaluyi-$ 900 yezigidi.
- IQumrhu leSizwe eliPhezulu leNdawo yokuPhakamisa indawo, ukuHlola, kunye nexesha, lijongene neGPS. I-Air Air yase-US igcine kwaye isebenze.
- Ukususela ngo-2017, ii-satellites ze-GPS zijikeleza umhlaba.
- I-GPS ibalulekile kwizixhobo, ukulungelelanisa, kunye neenkonzo esizithathayo ngokubalulekayo imihla ngemihla, njengeefowuni, iwashi, iikhomputha, ukubikezela imozulu, ukuhanjiswa kwamandla, ukuhamba, kunye nokukhawuleza / ukuphendula kwentlekele.
- Amashishini avela ebhankini, ukwakhiwa, ukukhwela kweenqwelo, nokuthunyelwa kwiimarike zezimali, ukulima, kunye nokunye okuncike ekuchanekeni kweGPS.
- I-GPS ibalulekile ekukhuselekeni kwelizwe. Zonke izixhobo zempi ezintsha zixhotywe nge-GPS.
- I-GPS ikwazisa umoya wehlabathi, ulwandle, kunye neendlela zokuthutha zendlela.
