Guhishura amabanga ya GNSS: Antena, Modules, na Receivers

Mu rwego rwo gushyira ibintu neza no kubigenzura neza, Gnss (Sisitemu y'ikoranabuhanga rya Global Navigation Satellite) igira uruhare runini. Ibice bitatu by'ingenzi - GNSS antenes, Moduli ya Gnsss, na Abakira GNSS– dukorera hamwe kugira ngo dukore neza aho duherereye – ibikoresho bizwi bikora neza nta nkomyi. Reka turebere hamwe isano yabyo, isano, n'itandukaniro ryabyo.

1. Antena za GNSS: Ibyuma bifata ibimenyetso

Antena za GNSSni ingabo zo ku murongo w’imbere zishinzwe gufata ibimenyetso bya satelite. Zakozwe kugira ngo zakire ibimenyetso bidakomeye biturutse ku matsinda y’inyenyeri nka GPS (Amerika), GLONASS (Uburusiya), BeiDou (Ubushinwa), na Galileo (Ubumwe bw’Uburayi). Izi antene zikora ku mirongo yihariye y’umuvuduko, nka L1 Band (~1575.42 MHz) ikoreshwa cyane mu bikorwa bya gisivili n’indi mirongo ikoreshwa mu buryo bwihariye.

Hari ubwoko bubiri bw'ingenzi: gikora n'ikidakora. Antena za GNSSIza ifite amplifier y’urusaku ruto (LNA). Iyi LNA ni ikintu gihindura umukino kuko yongera ibimenyetso bya satelite bitagaragara neza mbere yuko bigera kuri receiver, ibyo bikaba ari ingenzi mu bidukikije birimo ibimenyetso nk’ibiyaga cyangwa ibinyabiziga biri imbere mu mijyi. Ku rundi ruhande, izidakora, zidafite amplifier kandi zishingira ku bushobozi bwa receiver bwo kongera ijwi.

2. Module za GNSS: Ibigo byo Guhuza

 Moduli za GNSS, ni nk'ibigo by'amashanyarazi bito, byose muri kimwe. Bihuza ibice byinshi, harimo RF (radio frequency) circuitry, ndetse na antene (iyo byitwa modules za antene za GNSS). Izi module zagenewe koroshya guhuza ibikoresho bitandukanye bidafite insinga, byaba telefoni igendanwa, indege itagira umudende, cyangwa sisitemu yo gukurikirana imodoka.

IgisanzweModuli za GNSS,ishobora gushyigikira sisitemu nyinshi za satelite (GPS, BeiDou, GLONASS, Galileo, nibindi). Urugero, module zimwe na zimwe zishobora gukurikirana ibimenyetso bivuye kuri satelite zirenga 50 mu matsinda atandukanye y’inyenyeri. Zitunganya ibimenyetso byakiriwe (akenshi bifatwa na antene) kugira ngo zikuremo amakuru y’igihe n’andi makuru y’ingenzi akenewe mu gushyira ahagaragara. Mu by’ukuri, zikora nk'ikiraro kiri hagati yo gufata ibimenyetso bya antene n’aho uwakira aherereye byarangiye.

3. Abakira GNSS: Ibigo byo Kubara

Abakira GNSS niho haba habera igikorwa cyo kubara ahantu hadasanzwe. Iyo antene imaze gufata (niba bikenewe, nyuma yo kongera ingufu hakoreshejwe antene ikora) yohereza ibimenyetso bya satelite, kandi module igatunganya amakuru fatizo ku rugero runaka, icyuma gifata umwanya. Gikoresha amakuru y'igihe aturuka kuri ibyo bimenyetso kugira ngo kibare intera iri hagati ya buri satelite. Mu guhuza amakuru aturuka kuri satelite nibura enye binyuze mu buryo bwitwa trilateration, gishobora kumenya aho umukoresha aherereye nyayo.

Imashini zikira amakuru zishobora kuba ibikoresho byigenga cyangwa zigashyirwa muri sisitemu nini. Zigomba kuba zihuye n'ibimenyetso bitunganywa na modules kandi bigafatwa na antene. Imashini zikira amakuru zikoresha ikoranabuhanga rihanitse, nk'izikoreshwa mu bushakashatsi cyangwa mu ndege, zishobora kubyaza umusaruro ibimenyetso bikoresha frequency nyinshi biva muri modules na antene za GNSS kugira ngo zirusheho gukora neza, zirinde kubangamira no gukora amakosa y'ibimenyetso.

Isano n'Imibanire

●Urugendo rw'ikimenyetso: Antena ya GNSS ibanza gufata ibimenyetso bya satelite. Iyo ari antene ikora, yongera ibimenyetso. Ibi bimenyetso bihita bijya kuri GNSS Module, itunganya ibimenyetso bya RF mu buryo bworoshye. Amaherezo, GNSS Receiver ikoresha aya makuru yatunganyijwe kugira ngo ibare aho iri binyuze mu guteranya ibice bibiri.

●Kwishyira hamwe: Module za GNSS zikunze guhuza antene (zikora module za antene za GNSS) kugira ngo zigire igisubizo gito kandi cyoroshye guhuza. Kandi antene na module byombi ni ingenzi kugira ngo icyuma gifata amakuru kibone amakuru akenewe kugira ngo kimenye aho giherereye. Mu bikoresho byinshi, nka telefoni zigendanwa, ibi bice bitatu bishyirwa mu buryo antene iba igice cya module, kandi module ikorana n'urusobe rw'ibikoresho by'imbere byakira.

Itandukaniro

●Icyibandwaho cy'Imikorere:

○Antena zose zirebana no gufata ibimenyetso, kandi mu zikora, zigamije kongera imbaraga mbere y'igihe.

○Modules zibanda ku guhuza ibice n'ibimenyetso mbere yo gutunganya icyuma gitanga amakuru.

○Imashini zikira amakuru zigamije kubara ibintu bigoye kugira ngo zimenye aho ziherereye, umuvuduko n'igihe.

●Ishusho isanzwe:

○Antena zishobora kuba iz'inyuma (nk'antene yo hejuru y'imodoka) cyangwa iz'imbere (agace gato k'ibumba kari muri telefoni igendanwa), zifite imiterere n'ingano bitandukanye bitewe n'imiterere yazo (urugero, icyerekezo cyose kugira ngo zigere ku buryo bwagutse).

○Modules akenshi ziba ari nto, zishobora gushyirwaho ku buso, zagenewe kwinjira mu mbaho ​​z'ibikoresho.

○Udukoresho twakira amakuru dushobora kuva ku duce duto two mu gikoresho kugeza ku dukoresho tunini twigenga two gukoresha ibikoresho by’abahanga mu gupima.

●Ingorane za tekiniki:

○Antena zikora ku gufata ibimenyetso bya RF no kongera imbaraga (mu bihe bikora), zishingiye ku mahame ya electromagnetic.

○Module zikubiyemo guhuza imiyoboro ya RF, antene zishobora kuba, no gutunganya ibimenyetso by'ibanze, bisaba ubumenyi bwo guhuza ibikoresho n'uburyo bikoreshwa.

○Utumashini twakira amakuru ni two tugoye cyane, dukoresha uburyo bwo gukosora amakosa, no guhangana n'ibimenyetso byinshi bya satelite icyarimwe.

Mu gusoza, Antena za GNSS, Modules, na Receivers ni intwari zitavugwa inyuma ya buri porogaramu yo kugenzura neza, sisitemu yo gukurikirana imodoka, n'ubushakashatsi bugezweho. Gusobanukirwa inshingano zabo zidasanzwe n'uburyo bakorana bidufasha kwishimira ikoranabuhanga ritangaje rituma tuguma mu murongo mwiza mu isi yacu ya none ishingiye ku gace iherereyemo. Waba ukunda ikoranabuhanga, umuhanga mu bya porogaramu, cyangwa umuntu wishingikiriza kuri telefoni ye igendanwa kugira ngo aguhe amabwiriza, ibi bice ni inkingi y'uburambe bwo gushyira ibintu mu buryo buboneye akenshi dufata nk'ibintu bisanzwe.
