GPS-antenna: incazelo, inhloso, izici

GPS-antenna - lokhu ingenye izici ezibalulekile ingqalasizinda engenantambo. Kusukela ukukhetha okuhle ukuze operation efanele wathi amadivayisi zincike ukusebenza ohlelweni lonke, ngoba sithole ububanzi esiphezulu amadivaysi, iziteshi komkhawulokudonsa yokuxhumana futhi njll

Ngokungalungile ukukhwezwa GPS-antenna ngaphansi evumayo izimo zezulu, iyakwazi ukunikeza ubuhlobo sasivumela ehloniphekile, kodwa ngesikhathi imvula noma kweqhwa ngeke luntengantenge noma okunye konke lizoyeka ukusebenza. Naphezu alula sobala, ukuklanywa antenna ngezinye izikhathi sidinga umzamo owengeziwe nezisetshenziswa than dalo amadivayisi eziyinkimbinkimbi electronic.

Ukwahlukanisa GPS-antenna kunalokho iDemo. Ziyakwazi:

• yekwentiwa;
• kudivayisi yangaphandle futhi mountable litshaja (uhlobo obandayo).

Namuhla inikeza ukhetho olukhulu izitsha, kodwa ungakhohlwa ukuthi kungakhathaliseki ephephile futhi enamandla kanjani kungenzeka kudivayisi uma isetshenziswa nge yekhwalithi ephansi GPS-antenna, izici lobuchwepheshe kohlelo zikude ashiwo. Umsebenzi we-idivayisi ezinjalo ngeke ulethe yi kulindeleke ukuba umsebenzisi.

Active GPS-antenna uyisibonelo ejwayelekile yekwentiwa kanye amplifier esakhelwe ngaphakathi. Amadivayisi anjalo asetshenziswa GPS-abamukelayo, lapho azikho amadivayisi angaphakathi, kuleli cala ku isixhumi izindlu okukhipha for antenna kwangaphandle. Imishini esebenzayo njengabakhulu e ukuzwela izimo yokwenziwa, yini ukwandisa isilinganiso isignali level umsindo ezingeni, ukunciphisa umthelela noma yikuphi ukuphazamiseka leze. Isignali kusukela antenna yokwenziwa kakhulu wadalula emisebeni kagesi, futhi ngenxa yalokho ufike esikhumulweni umamukeli usesimweni esikhululekile futhi angahleliwe. isignali bedivayisi esebenzayo kuyahluka amplitude okukhulu kunalokhu ka yekwentiwa. Ngokukhetha GPS-antenna kufanele ngamuntu munye, ikhumbula uhlobo umamukeli, ngoba amanye amadivayisi kungenzeka ibe esakhelwe antenna amplifier.

Abakhi GPS-antenna ukunikela anhlobonhlobo antenna zangaphakathi nezangaphandle. Ziyahlukahluka kuye ngokuya supply voltage (3-5V) abe ngaphezu yokukhulisa umsindo isignali futhi bandpass izihlungi, okuyinto bafa amasignali nezingahlobene nendaba ngaphandle oyifunayo imvamisa ububanzi. GPS-antenna (imoto) usebenza imvamisa 1575,42 ± 3 MHz. Uma sicabangela ububanzi bandpass isihlungi kweqiwe band 10 MHz. Inani isilinganiso antenna kubhedere 4 DB, lo 1 iviki amandla ukushabalalisa. Amadivayisi anjalo ukwazi ukunikeza ukusebenza onokwethenjelwa kule uhla lokushisa kusuka degree angu -40 kuya +100 centigrade ngesikhathi umswakama nesihlobo 100 amaphesenti. Antenna anemisila izinhlobo ezahlukene izintambo nezinhlobo ezahlukene nezixhumi, ukuze ukwazi ukusebenzisa kwabo nanoma uhlobo ethola amadivaysi. Ubude ikhebula lingafika ngamamitha amahlanu, ngenxa okuyinto wenza kube lula ukufakwa kwe-GPS-antenna.

Kufinyeta, siphawula ukuthi amadivayisi yesimanje zithuthukuselwe ngokuvumelana nezimfuno izinqumo ehlukahlukene, ezifana inzuzo okusezingeni eliphezulu, low power ukusetshenziswa, amanani aphansi, usayizi amancane.
