GPS zvigadzirisheni zvinoshandisa kudonhedzana kuisa nzvimbo panzvimbo yepasi
Global Positioning System maitiro anoshandisa nzira yemasvomhu yekudengenyeka kuti aone kushandiswa kwevashandi, kukurumidza, uye kukwirira. GPS zvigaro zvinowanzogamuchira uye kuongorora zviratidzo zveredhiyo kubva kune dzakawanda dze satellites GPS. Vanoshandisa zviratidzo izvi kuti verengere nzvimbo yakananga kana kuti mararamiro kune imwe neimwe satanasi iri kuteverwa.
Izvozvo zvinoshandiswa sei
Kuparadzana inzira yakanakisisa yekutatura. Dhiyabhorosi kubva kune imwe sataiti inotarisa nzvimbo yakareba yepasi. Kuwedzera dheta kubva kune yechipiri satellite kunowedzera nzvimbo iyo kusvika kunharaunda iyo mazamu maviri e satanese data inowanikwa. Kuwedzera data kubva kune chetatu chetaneti kunopa nzvimbo yakanyatsonaka, uye mapoka ose eGPS anoda ma satellite matatu kuti awane nzvimbo yakarurama. Dhiyabhorosi kubva kunechina satetiti-kana masereti mana-anowedzera zvakajeka uye anogadzira kukwirira kwakarurama kana, kana pane ndege, kure. GPS vagamuchirwo vanowanzoona satelliti mana kana manomwe kana imwe chete panguva imwe chete uye vanoshandisa dutu kuti vaongorore ruzivo.
Dhipatimendi reUnited States rekudzivirirwa rinochengetedza ma satellite makumi maviri nemaviri anotumira pasi pasi rose. Gadhi yako GPS inogona kuramba yakabatana nematanhatu ma satellite pasinei nokuti uri kupi pasi, kunyange mumatanda kana masvingo makuru ane zvivako zvirefu. Chimwe nechimwe chendaneti chinotenderera pasi kaviri pazuva, nguva dzose kutumira zviratidzo pasi pano, pakakwirira anenge anenge 12 500 makiromita. Satellites anomhanya nesimba rezuva uye ane mabhetri ekuchengetedza.
GPS History
GPS yakatangwa muna 1978 nekutangwa kwekutanga shanduro. Yakarongedzwa uye yakashandiswa chete nemauto kusvika kuma1980. Nzvimbo yakakwana yevanhu makumi maviri nematanhatu ekushandira maStellite anotungamirirwa neU.S.SIA yakanga isiri nzvimbo kusvika muna 1994.
Apo GPS inokundikana
Apo gwagwa re GPS rinogamuchira zvisingakwanisi satellite data nokuti haikwanise kutarisa satetiti yakakwana, kuparara kunokundikana. Mufambisi wengarava anozivisa mushumiri panzvimbo yekupa ruzivo rwakakosha ruzivo. Satellite dzimwe nguva inokundikana kwenguva pfupi nokuti zviratidzo zvinotama zvishoma nezvishoma nemhaka yezvinhu zviri mu troposphere uye ionosphere. Zviratidzo zvinogonawo kubvisa dzimwe zvigadziro uye zvivako pasi pano, zvichikonzera kukanganisa kwekutapudza.
