GPS-eriyali: inkcazelo, injongo, iimpawu

GPS-eriyali - le yenye yezona zinto zibalulekileyo kwezibonelelo wireless. Ukususela ukhetho ekunene kunye nokusebenza ngokuchanekileyo uthe iingcinga zokuxhomekeka ukusebenza yonke le nkqubo, ekubeni ubone uluhlu iphezulu izixhobo, imijelo bandwidth yonxibelelwano kunye njl

Phosakeleyo imvelaphi inyuselwa GPS-eriyali phantsi kweemeko imozulu intle, uyakwazi ukunika ulwalamano ngokwanelisayo endilisekileyo, kodwa ngexesha imvula okanye ukuwa iya kufadalala okanye bonke baya kuyeka ukusebenza. Nangona elula ibonakale, ukuyilwa eriyali ngamanye amaxesha kufuna umgudu kunye nezibonelelo ngaphezu ukudalwa izixhobo ezintsonkothileyo-elektroniki.

Ukuhlelwa le GPS-antenna obufutshane. Zezi:

• esebenzayo neyokwenziwa;
• sixhobo sangaphandle uze mountable kwintlawulo (uhlobo engathethekiyo).

Namhlanje inikeza ukhetho olukhulu izitya, kodwa musa ukulibala ukuba kungakhathaliseki ekhuselekileyo kangakanani kwaye enamandla isenokuba ifowuni ukuba ezakusetyenziswa elisezantsi-umgangatho GPS-eriyali, iimpawu zobugcisa kwinkqubo kude kwezo lowu. Umsebenzi kwisixhobo onjalo akayi kuyitshabalalisa isiphumo kulindeleke ukuba umsebenzisi.

Active GPS-eriyali kukuba imodeli eqhelekileyo kwisixando kunye msindo eyakhelwe-ngaphakathi. izixhobo ezinjalo asetyenziswa ngayo GPS-balwamkele, apho akukho izixhobo zangaphakathi, kulo mzekelo kwi Isidibanisi imveliso yokuhlala-eriyali lwangaphandle. Izixhobo ezsbenzayo iphakeme uvakalelo kwiimeko zezenzi, bandile umlinganiselo kwinqanaba uphawu ukuya kwinqanaba ingxolo, ukunciphisa impembelelo naluphi na uphazamiseko na. Uphawu ukusuka eriyali kwisixando usekuhleni kakhulu kwimitha magnetic, yaye ngenxa yoko zifika kwisamkeli ikwimeko nesi- inokutyhefeka. uphawu isixhobo esebenzayo kwahlukile awo likhulu kakhulu ngaphezu koko ungawusebenzisi. Ngokukhetha i GPS-eriyali kufuneka individualised, kuthathelwa ingqalelo uhlobo receiver, ngenxa yokuba ezinye izixhobo kungenzeka ibe eyakhelwe-ngaphakathi eriyali umsindo.

Kubavelisi GPS-eriyali zinika uluhlu olubanzi eriyali lwangaphakathi nolwangaphandle. Ahluke ngokwemiqathango ombane yonikezelo (3-5V) abe ukongeza a yokukhulisa isignali kunye izihluzi bandpass, leyo, banqunyulwe Imiqondiso nendaba ngaphandle uluhlu kumaza afunekayo. GPS-eriyali (isithuthi) isebenza ngexesha rhoqo 1575,42 ± 3 MHz. Ngenxa ububanzi bandpass lokucoca Sexy ibhendi MHz-10. Ixabiso avareji eriyali Inzuzo 4 dB, lo 1w amandla ukusasaza. izixhobo ezinjalo nako ukunika intsebenzo enokuthenjwa kuluhlu lobushushu ukusuka degrees -40 ukuya +100 C kwindawo ukufuma usisizalwane 100 ekhulwini. Eriyali baxhotyiswa oluneentlobo ezahlukeneyo kweentambo ngeentlobo ezahlukeneyo izihlanganisi, ukuze uzisebenzise kunye naluphi na uhlobo nokufumana izixhobo. Ubude cable kunokuba ukuya kwiimitha ezintlanu, ngenxa leyo lula kakhulu ukufakela GPS-eriyali.

Ukushwankathela, siphawula ukuba izixhobo zale mihla ukuba isebenze ngokungqinelana izigqibo ezahlukeneyo nqobo, ezifana inzuzo aphezulu, ukhwaliti amandla, ixabiso eliphantsi, ubungakanani omncinane.
