I-IP67 GPS yangaphandle Antenna 1575.42 MHz 34 dBi
Isingeniso Somkhiqizo
I-IP67 GPS Active Antenna yangaphandle enemvamisa engu-1575.42 MHz kanye nenzuzo efinyelela ku-34dBi.Idizayinelwe ukusetshenziswa ngaphandle, i-antenna ilungele izinhlelo zokusebenza ezahlukahlukene ezihlanganisa ukulandelela isitimela se-RTC, ukulandelela izimoto zamasosha namafa, ukulima okunembayo, nokulungiswa komehluko.
Imvamisa yale antenna esebenzayo yi-1575.42 MHz, okuqinisekisa ukwamukela okuqinile nokuthembekile kwesignali ye-GPS.Inenzuzo ephezulu ye-34dBi, eqinisekisa ukusebenza okuhle kakhulu ngisho nasezindaweni ezikude neziyinselele.Kungakhathaliseki ukuthi ulandelela isitoko, izimoto zamasosha noma izinto zezolimo, lolu luthi luzokunikeza idatha enembile nenembile.
Izinti zethu ezilinganiselwe nge-IP67 ziyakwazi ukumelana nezimo zangaphandle ezihlanganisa imvula enkulu nothuli.Ukwakhiwa kwayo okuqinile kuqinisekisa ukusebenza okuhlala isikhathi eside futhi ilungele ukusetshenziswa ezindaweni ezinokhahlo.Noma ngabe ukushisa okushisayo, amakhaza ashubisa umnkantsha noma imvula enamandla, lolu luthi luzoqhubeka nokuletha imiphumela emihle.
Lolu thi olusebenzayo lwe-GPS luklanyelwe ukulandelela isitoko esigingqikayo se-RTC, ukulandelela izimoto zamasosha kanye nokulandelela impahla, ezolimo ngokunemba kanye nezinhlelo zokusebenza zokulungisa umehluko.Ngokuzwela kwayo okuphezulu nokunemba, iqinisekisa ukulandela ngomkhondo nokuqoqwa kwedatha.Noma ngabe udinga ukugada ukuhamba kwezimoto, ukulandelela impahla noma uqinisekise ukuma okunembile kwezolimo, le-antenna ilungile.
Ngezici zabo ezithuthukile kanye nomklamo omangelengele, izimpondo zethu ze-GPS ezisebenzayo zifanele izimboni nezinhlelo zokusebenza ezihlukahlukene.Ukuguquguquka kwayo kuyenza ibe yithuluzi elisebenzayo lochwepheshe kwezokuthutha, ezokuvikela, ezolimo nokunye.Uma kukhulunywa ngokulandelela nokubeka indawo, le antenna ngeke idumaze.
Kafushane, i-antenna yethu yangaphandle ye-IP67 GPS esebenzayo ihlanganisa izici ezinamandla njengefrikhwensi engu-1575.42 MHz, inzuzo engu-34dBi kanye nesilinganiso se-IP67.Ukuqina nokuthembeka kwayo kuyenza ilungele ukusetshenziswa ngaphandle, iqinisekisa ukulandelwa okunembayo, okunembile kanye nokuma.Noma ngabe usembonini yezokuthutha, ezokuvikela noma yezolimo, lolu luthi luyisinqumo esihle kakhulu kuzo zonke izidingo zakho ze-GPS.Izwa ukusebenza okuthembekile futhi uthole okuningi kumathrekhi akho ngothi lwethu olusebenzayo lwe-GPS.
