Ama-satellites awalandela lesi simanga samanje
I-Global Positioning System (GPS) isimanga sezobuchwepheshe esenziwe yiqembu lama satellites ekujikelezeni komhlaba. Ihambisa izimpawu ezicacile, ivumela abamukeli be-GPS ukuthi babone futhi babonise indawo enembile, isivinini, nesikhathi somsebenzisi kumsebenzisi. I-GPS ingumnikazi we-US
Ngokubamba amasignali kuma-satellites, abamukeli be-GPS bayakwazi ukusebenzisa isimiso semathempeli sokuqothula ukukhomba indawo yakho. Ngokungeziwe kwamandla wekhompuyutha nedatha egcinwe ememori njengezimamephu zomgwaqo, amaphuzu ezithakazelisayo, ulwazi lwezobuciko, nokunye okuningi, abamukelayo be-GPS bakwazi ukuguqula indawo, isivinini, kanye nolwazi isikhathi sibe yindlela yokubonisa ewusizo.
Invention and Evolution ye-GPS
I-GPS yasungulwa ekuqaleni uMnyango wezokuVikela waseMelika (DOD) njengesicelo sezempi. Uhlelo luye lwasebenza kusukela ekuqaleni kwawo-1980 kodwa lwaqala ukusiza izakhamuzi ngasekupheleni kweminyaka yama-1990 ngokufika kwamadivayisi abathengi abasixhasa. I-GPS yabathengi selokhu yaba imboni yezigidigidi zamadola ezinemikhiqizo eminingi, amasevisi, nezinsiza ezixhunywe nge-intanethi. Njengezobuchwepheshe abaningi, ukuthuthukiswa kwayo kuqhubeka; kuyilapho kuyimangalisa yangempela yanamuhla, onjiniyela baqaphela ukulinganiselwa kwawo futhi basebenza njalo ukuze banqobe.
Amandla we-GPS
- I-GPS isebenza ngokunembile kuzo zonke izimo zezulu, nxazonke kwewashi, nasemhlabeni jikelele.
- Ayikho imali yokubhaliselwe yokusebenzisa izimpawu ze-GPS.
- Abamukeli be-GPS ngokuvamile banembile ngaphakathi kwamamitha angu-15, futhi amamodeli amasha asebenzisa isistimu ye-Wide Area Augmentation System (WAAS) enembile ngaphakathi kwamamitha amathathu.
Ukulinganiselwa kwe-GPS
- Izimpawu ze-GPS zingavinjelwa amahlathi aqinile, izindonga ze-canyon, izakhiwo eziphakeme, amabhuloho, izindonga, nokunye okunjalo, okwenza ukuhamba kwe-GPS okunembile kunzima noma kungenzeki.
- Ngokufanayo, i-GPS ayisebenzi kahle ezindaweni zangaphakathi nangaphansi komhlaba.
- Ukugcinwa kwesathelayithi, ukuphazamiseka kwomsakazo, neziphepho zelanga kungabangela izikhala zokufaka.
I-International Effort
I-GPS ephethwe yi-US kanye ne-operated GPS yisistimu yokuhamba nge-satellites esekelwe indawo esetshenziswa kakhulu emhlabeni, kepha i-constellation ye-satellite ye-GLONASS yaseRussia inikeza nesevisi yomhlaba wonke. Amanye amadivayisi we-GPS abathengi asebenzisa kokubili izinhlelo ukuthuthukisa ukunemba nokwandisa amathuba okuthola idatha eyanele yokuma.
Amaqiniso Okuthakazelisayo Nge-GPS
Ukusebenza kwe-GPS kuyimfihlakalo kubantu abaningi abasebenzisa nsuku zonke. Lezi zinto ezingase zenzeke zingase zikumangaze:
- I-GPS ye-Military isebenzisa ama-frequencies amabili, kuyilapho umphakathi ungasebenzisa eyodwa kuphela. Lokhu kwandisa ukunemba. Amadivaysi e-Dual-frequency GPS atholakala kubahlali, kodwa izindleko nezayizi zabo zenza zingasebenzi.
- Uhulumeni wase-US uhlanganyele ohlelweni oluqhubekayo, olwenziwe ngamabhiliyoni angama-dollar nokuthuthukiswa kwamanje.
- Abakhokhi bentela base-US bakhokhela izinsizakalo zezwe ze-GPS, ikakhulukazi kuMnyango Wezokuvikela. Isabelomali sika-2017 sasingaba ngu-$ 900 million.
- Iqembu elihlangene laseMelika elibambisene nomphakathi / lezempi, iKomidi eliPhezulu likaZwelonke lokuPhakamisa indawo, UkuHlola, nokuPhatha, liqondisa i-GPS. I-US Air Force igcine futhi isebenze.
- Kusukela ngo-2017, ama-satellites angu-24 ajikeleza i-GPS emhlabeni.
- I-GPS ibalulekile emadivaysi, okulula, nezinsizakalo esithatha kalula ngosuku lonke, njengamafoni, amawashi, amakhompyutha, ukubikezela isimo sezulu, ukulethwa kwamandla, ukuhamba, nokuphuthumayo / impendulo yezinhlekelele.
- Amabhizinisi avela ebhange, ukwakhiwa, ukuhamba kwezindiza, nokuthunyelwa ezimakethe zezimali, ukulima, nokunye okuningi kuncike ekutheni kwe-GPS.
- I-GPS ibalulekile ekuvikelekeni kazwelonke. Yonke imishini yamasosha entsha ihlonywe yi-GPS.
- I-GPS izisa umoya wezwe, ulwandle, kanye nemigwaqo yokuhamba endleleni.
