I-antenna ye-GPS VS GNSS?
Inhloso kanye Nokumbozwa
Ezweni lobuchwepheshe bokuzulazula nokubeka izinto endaweni, Ama-antenna e-GPS kanye ne-GNSSidlala indima ebalulekile. Kodwa-ke, abantu abaningi abaqapheli umehluko phakathi kwalokhu okubili futhi bavame ukusebenzisa amagama ngokushintshana. Kuleli fayela, sizohlola umehluko phakathi Ama-antenna e-GPS kanye ne-GNSS, okukhanyisa ukusebenza kwazo okuyingqayizivele kanye nezinhlelo zokusebenza.
Ama-Gps, emele i-Global Positioning System, iyisistimu yokuzulazula yesathelayithi eyaziwayo enikeza ulwazi lwendawo nesikhathi kuzo zonke izimo zezulu, noma kuphi eMhlabeni noma eduze kwawo lapho kunomugqa ongabonakali wokubona amasathelayithi e-GPS amane noma ngaphezulu.Ama-antenna e-GPSzenzelwe ngqo ukwamukela izimpawu ezivela ku-GPS satellite constellation futhi zivame ukusetshenziswa ezinhlelweni ezahlukene njengokuzulazula kwezimoto, ukuzulazula olwandle, kanye nemisebenzi yokuzijabulisa yangaphandle.
Ngokolunye uhlangothi,I-Gnss, noma i-Global Navigation Satellite System, igama elihlanganisa izinhlelo eziningi zokuzulazula kwesathelayithi, okuhlanganisa i-GPS, i-GLONASS (i-Global Navigation Satellite System), i-Galileo, ne-BeiDou. Ama-antenna e-GNSS ayakwazi ukwamukela izimpawu ezivela kumaqoqo amaningi ezinkanyezi zesathelayithi, ahlinzeka ngolwazi olunembile noluthembekile lokuma uma kuqhathaniswa nama-antenna e-GPS kuphela. Leli khono lokwamukela izimpawu ezivela ezinhlelweni eziningi zesathelayithi lizuzisa kakhulu ezindaweni lapho izimpawu ze-GPS zingase zivinjelwe khona, njengezigodi zasemadolobheni noma amaqabunga aminyene.
Ukutholakala Nokuthembeka
I-GPS itholakala kabanzi futhi ithembekile, inezinhlelo zokusebenza eziningi ezimbonini ezifana nezokuthutha, ezolimo, kanye nezokuzijabulisa. Kodwa-ke, ukutholakala kwayo kanye nokuthembeka kwayo kungathinteka yizici ezifana nokuxinana kwesignali noma ukuphazamiseka.
Ngakolunye uhlangothi, i-GNSS inikeza ukutholakala okuqinile kanye nokuthembeka ngenxa yokusebenzisa izinhlelo eziningi. Uma uhlelo olulodwa lungatholakali noma lungathembekile, abasebenzisi basengakwazi ukufinyelela ulwazi lwendawo kanye nokuzulazula kusuka kwezinye izinhlelo. Lokhu kungaba wusizo ikakhulukazi ezindaweni lapho ukumbozwa kwe-GPS kulinganiselwe noma kungathembekile.
Umehluko oyinhloko
Umehluko oyinhloko
Omunye wemehluko omkhulu phakathi Ama-antenna e-GPS kanye ne-GNSSkulele ekumbozweni kwawo kanye nokunemba kwawo. Nakuba ama-antenna e-GPS ekhawulelwe ekwamukeleni izimpawu ezivela ku-GPS satellite constellation, Ama-antenna e-GNSSbanekhono lokwamukela izimpawu ezivela ezinkanyezini eziningi zesathelayithi, okuholela ekuqondeni nasekuthembekeni okuthuthukisiwe, ikakhulukazi ezindaweni ezinzima. Lokhu kwenza ama-antenna e-GNSS abe yisinqumo esikhethwayo sezinhlelo zokusebenza ezidinga indawo enembile kakhulu, njengokuhlola, ezolimo ezinembile, kanye nokwakha.
Omunye umehluko obalulekile ukutholakala kwezimpawu. Ama-antenna e-GPSbathembele kuphela ezimpawini ezidluliselwa yi-GPS satellite constellation, ezingase zibe sengozini yokuvaleka noma ukuphazamiseka kwezimpawini ezindaweni ezithile. Ngokuphambene nalokho, ama-antenna e-GNSS angasebenzisa izimpawu ezivela ezinhlelweni eziningi zesathelayithi, okwandisa ukutholakala kwezimpawini futhi kuncishiswe umthelela wokuvaleka noma ukuphazamiseka kwezimpawini. Lokhu kwenza ama-antenna e-GNSS abe nokuguquguquka okuningi futhi aqine ezimweni zokusebenza ezahlukahlukene.
