GPS-pūihi: whakaahuatanga, whakaaro, āhuatanga

GPS-pūihi - ko tetahi o nga mea timatanga tino nui o te hanganga ahokore tenei. Mai i te whiriwhiri tika me te mahi tika o mea whakaaro whakawhirinaki i runga i te mahi o te pūnaha katoa, mai whakatau ratou te whānuitanga mōrahi o te whakaaro, takere hōkaiipurangi o kōrero me etc.

Hē eke GPS-pūihi i raro i ngā āhuatanga huarere pai, taea ki te whakarato i te hononga tika tika ko, engari i roto i te ua hiona ranei ka ngoikore atu ka mutu katoa mahi ranei. Ahakoa tona tapatahi kitea, ētahi wā titau atu kaha, me ngā rauemi atu i te hanganga o ngā pūrere hiko matatini te hoahoa o Antennas.

Ko kaua poto Whakarōpū o te GPS-pūihi. Ko ratou:

• kaha, me te hāngū;
• pūrere waho, me te mountable i runga i tiaki (whakapuru momo).

I teie mahana tuku he kōwhiringa nui o rihi, engari e kore e wareware e kia noa'tu te haumaru, me te kaha hei te pūrere ki te te whakamahia te reira ki te GPS-pūihi iti-te kounga, e matara i te hunga kī nga āhuatanga hangarau o te pūnaha. Ko te mahi o te pūrere taua e kore e kawea ki te hua e tūmanakohia ana ki te kaiwhakamahi.

Active GPS-pūihi ko te tauira hāngū paerewa ki tīwerawera hanga-i roto i. Taua whakaaro e whakamahia i roto i te GPS-farii, i roto i nei i reira he kore whakaaro ā, i roto i tenei take i runga i te tūhono putanga whare mo te pūihi waho. He pai i roto i te tūtohutanga wā hāngū whakaaro Hohe, hua ana o ratou te ōwehenga o te taumata tohu ki te taumata haruru, whakaiti i te pānga o tetahi raweketia katoa. Ko te tohu i te pūihi hāngū te kaha kitea ki radiation hiko, me rite ki te hua tae i te kaiwhiwhi i roto i te huru ngāwari, me te fakakehei. kaha tohu pūrere rerekē tīwera nui nui atu taua o hāngū. Na roto i te kōwhiri i te GPS-pūihi kia kia wehewehea, tango ki pūkete te momo o kaiwhiwhi, no te mea kia roto kē etahi whakaaro he hanga-i roto i te tīwerawera pūihi.

Manufacturers o GPS-Antennas whakahere he whānui o Antennas roto, o waho ngā. rerekē ratou i roto i ngā o te ngaohiko supply (3-5V) i roto i te tua i te amplifiers tohu me ngā tātari bandpass, e kua tapahia tohu no rapae i waho te awhe auau hiahiatia. GPS-pūihi (waka) mahi i te auautanga 1575,42 ± 3 MHz. I roto i te tirohanga o te whanui tātari bandpass pekepeke ropu ko 10 MHz. Ko te uara toharite o te pūihi taonga ko 4 DB, te 1W mana tohanga. E taea e ki te whakarato mahi pono i roto i te whānuitanga pāmahana i -40 ki te +100 nekehanga centigrade i te haumākū whanaunga o 100 ōrau taua whakaaro. E rite rawa Antennas ki ngā momo rerekē o te taura ki ngā momo rerekē o tūhono, kia taea e koe te whakamahi i ratou ki tetahi momo o te fariiraa i ngā pūrere. Ka taea e te roa taura kia ake ki rima mita, no te mea o nei tino e ohie te tāutanga o te GPS-pūihi.

Hei whakarāpopoto, mōhio tatou e kua papaitia whakaaro hou kia rite ki ngā paearu whakatau, pēnei i te taonga nui, iti kohi mana, utu iti, rahi iti.
