I-GPS inikeza ulwazi olubalulekile emaZweni Okulwa
Ukusho ukuthi ama-satellite akha i-Global Positioning System's constellation yi-revolutionary inventory yi-understating of the 21st century. Ngendlela yokuzulazula nemifanekiso yayo, i-Global Positioning Systems (GPS) ibe enye yezobuchwepheshe obubaluleke kakhulu empini yase-US kusukela ekuthuthukiseni kwayo phakathi nawo-1900. Sebe yingxenye ebalulekile yezimpilo zethu kanye nezempi ukuthi manje ine-website yayo kahulumeni kubasebenzisi bomuntu siqu nabathengisi.
I-GPS iyisibonelo esihle sobuchwepheshe obuye besuka ku-tactical kuya ekusebenzeni.
Umlando we-GPS: Ukusiza Amasosha Ukuhamba
Eyaziwa yiziqalo zayo "GPS," i-Global Positioning System isetshenziselwe ukuhweba kuphela kusukela ngo-1994. Futhi uhlelo lwe-satellites lokuhamba nge-satellite olusekelwe endaweni yonke e-US lwaziwa kakhulu ngokusiza abashayeli bezemoto ukuthi bahambe ngendlela emigwaqweni yasemigwaqeni e-Smartphones kanye nemoto esekelwe izinhlelo.
Kodwa ubuchwepheshe - obuhlinzeka ngezinsizakalo zokuhamba ezinokwethenjelwa nemifanekiso eningiliziwe noma kuphi emhlabeni - kuye kwabonakala kuyithuluzi elibalulekile emaqenjini aseMelika namanye amabutho okuzivikela emhlabeni jikelele kusukela ngawo-1980.
Njengoba unamandla okunikeza ukubeka okunembile ngokuqhubekayo, imini noma ubusuku, kunoma yiziphi izimo, i-GPS isize amabutho omhlaba e-Iraq nase-Afghanistan ahambe ngezindawo zasemakhaya ezingenalutho ezinamatshe ambalwa noma izici ezihlukaniswayo. Baye babonisa ukuthi banokwethenjelwa ngeziphepho zesihlabathi uma ukubonakala kuncishisiwe.
Idivaysi ye-GPS ibuye ikwazi ukulwa namasosha ase-US kanye nabalingani bayo ukuba bahlukanise amasosha abungane nabasosha - ukunciphisa izenzakalo zomlilo onobungane ezindaweni zokulwa.
Indlela iStellation yeStellation esebenza ngayo
I-Global Positioning System - eyaziwa nangokuthi i-NavStar yombuthano umhlaba kabili ngosuku. Uma unomamukeli we-GPS emhlabathini, umamukeli we-GPS uthatha lolu lwazi futhi usebenzisa ama-satellite ama-3-4 ukuze alingise indawo ngqo yomsebenzisi.
Yisikhathi esiyisisekelo, ibanga, isivinini, izibalo zeziqondiso zama-satellites kulabo abamukelayo abasebenzisa ukuthola ukuthi umamukeli uvela kude kangakanani kusuka kuma-satellite wokubeka. Uhlu lwesikhathi litshela umamukeli we GPS ukuthi kude kangakanani i-satellite. Manje, ngezilinganiso zamakhilomitha avela kuma-satellite ambalwa, umamukeli anganquma isikhundla somsebenzisi futhi asibonise ebalazweni leyunithi.
Umamukeli we-GPS kufanele avaliwe kusignali okungenani ama-satellite amathathu ukuze abale ukuhamba kwebala nobude nokulandelela. Ngama-satellite amane noma ngaphezulu ekubonweni, umamukeli anganquma isikhundla se-3-D yomsebenzisi (latitude, ubude, nokuphakama). I-GPS iyakwazi ukubala olunye ulwazi, njengejubane, ukuthwala, ithrekhi, ibanga lokuhamba, ibanga ukuya endaweni, ukuphuma kwelanga nokushona kwelanga isikhathi nokuningi.
Isicelo esikhulu
Amadivaysi asekhona ezindizeni, e-helicopter, emajetsheni, emikhumbi yempi yempi, emotweni yemvelo kanye nasemabuthweni ngabanye. I-North Atlantic Treaty Organization (i-NATO) yenza amadivayisi we-GPS ajwayelekile ukusetshenziswa kwezizwe zalo malunga.
Izithombe ezitholakala nge-satellite ezinikezwa yi-GPS nazo zibaluleke kakhulu ekuhlakanipheni kwezempi . Amasosha asebenza ekuhlakanipheni athembele ku-GPS ngolwazi oluvumela ukuba benze izinqumo zokusebenza nezindlela zangempela ngesikhathi sangempela.
Ukusetshenziswa Kwesikhathi Esizayo Kwedivayisi
Kusukela ngo-September 1, 2016, kwakukhona ama-satellite satellites angu-31 ku-constellation ye-GPS. Akubandakanyi ama-satellite e-GPS ahlehlisiwe agcinwe ku-orbit uma kunesidingo sokuwavuselela kabusha. Ukubalwa kwama-satellites okusebenzayo kuphulwa ngama-satellite angu-12 aqaliswe ngo-1997-2004, 7 aqaliswa ngo-2004 -2009, futhi 12 aqaliswa ngo-2010-2016 ngama-satellites angu-31 asebenzayo okwenza ama-satellites angu-31 asebenzayo okwenza zonke izinhlelo ze-GPS zisebenze . Kube nezinhlelo zamanye ama-satellite ayishumi ukuze zifinyelele ku-orbit ngo-2016 -2017 ukuze zishintshe ama-satellites asebekhulile asebenze ngaphesheya kokuphila kwabo okucatshangelwe. Ukuze uthole ukwaziswa okwengeziwe kwesimo se-constellation, vakashela iwebhusayithi ye-NAVCEN eqhutshwa yi-Coast Guard.
Amaqembu ezombusazwe emhlabeni wonke abheka ukusetshenziswa okusha kwe-GPS.
Amadivayisi ayengezwa ngezikhali nezibhamu, kanti amanye amazwe - njenge-Army yase-Israel - ahlola ukuthi kungenzeka ukufaka amadivaysi e-GPS emigodini yempi kanye nemifomu ukuze abalawuli bezinsimu bakwazi ukulandelela ukuhamba kwawo amasosha ngesikhathi sangempela. Uhulumeni wase-Israel uthe ukufaka amadivaysi e-GPS amasunifomu amasosha kungasiza ekunciphiseni izigameko zomlilo onobungane.
