Digital Compass - indlalifa ikhampasi kazibuthe

Kukhona nezimpikiswano emlandweni, kusobala esasizobhujiswa ekubeni noma kunjalo impendulo engafanele, ngoba zisekelwe iphutha elibi kakhulu. Esinye salezo kwavela muva nje, njengoba isintu eseke uhlelo of global positioning: umuntu abe ngqo - ikhampasi digital noma kazibuthe? Abantu babuza lo mbuzo, ngokusobala into engakaze yenziwe esikolweni geography izifundo ...

Lena incazelo yokuqala umbuzo: ku onjani isigxobo ufuna ukuya?

Kubonakala sengathi impendulo isobala. bubonakala nakakhulu sezidomu ne workshop ku geography, uma idivayisi for orienting ikhampasi uHadrian wakhonza emhlabathini (manje into ezingavamile, konje), perforce wafunda ukuthi blue ekupheleni inaliti yekhampasi njalo uveza enyakatho. Ngakho, lapho isigxobo enyakatho. Ngakho, ebomvu ukuphela - eningizimu.

Kunengqondo, kodwa akusilo iqiniso lelo. Ukusabela ngale ndlela kungafaneleka, isibonelo, ekhulwini XVIII, lapho sphericity Zomhlaba isivele luhlolwe kodwa phezu kwekhanda lakhe futhi "antipode" ohlangothini has noyedwa abacwaningi akazange ababukele. Nokho, umlando nekhampasi ngokuvamile akukho izingongolo wayazi ebusheni bakhe. ekuqaleni nje ne yamaShayina yasendulo, siqhaphele ukuthi uzibuthe yensimbi inaliti njalo uveza luhamba luye ohlangothini olulodwa, futhi ukujabulela navigation ezweni nasolwandle. Lapho ikhampasi ekhulwini XIII sisendleleni ngokusebenzisa Arabhu wafika e-Europe, izinduna imikhumbi ekuqaleni wangabaza ukusebenzisa eseyintsha - babesaba emangalelwa obuthakathi. Kodwa lapho esiphethweni ukuthi kwakwenzekani, ngaqala zpoha Omkhulu okutholakele womhlaba, okuyiwona ikhampasi weqiniso engena uhlu ezisunguliwe enkulu yingqondo yomuntu.

Ekhulwini XIX, nge esingaba iminyaka engu-10 i-British wamazwe polar Dzhon Ross kanye nomshana wakhe James ufinyelelwe, ngokulandelana, nasenyakatho, naseningizimu izingongolo kazibuthe Zomhlaba. Futhi ngokushesha sinqume ukuthi abazi uqondane izigxobo kwendawo.

Kamuva kwathi akwanele - ngisho drift on surface eMhlabeni. Kwakungafanele bazikhohlwe ukuthi ikhampasi digital, i-magnetic akukho ukweba. I ngesivinini esingamakhilomitha ukunyakaza - 10 amakhilomitha ngonyaka. eminyaka Mayelana emithathu nengxenye, enyakatho magnetic wazulazula insimu yase-Canada, futhi engxenyeni kwekhulu elidlule yesibili, konke kusenjalo ne "esibi" Izinga (ngo-2009 - 64 amakhilomitha ngonyaka) waklebhula eRussia, kuya Peninsula Taimyr. Ngakho manje magnetic Ikhampasi inaliti, uma ulandela kahle kuzokusa-Arctic ice iphakethe, kuze kube seqophelweni nge izixhumanisi 85 ° 54 'imizuzu enyakatho nenkabazwe-147 degrees longitude empumalanga.

Manje njengoba sesikhulumile ngo waqonda, siyowuqonda ikhampasi digital, kuba electronic. Ayikho odonsa lapha, yebo, kungadingeki. Nesamukeli amasignali kusuka iziphuphutheki GPS noma GLONASS inquma indawo yayo, ubeka idatha igridi Ukudidiyela ibalazwe futhi ngokushesha ubonisa indawo kwesikrini enyakatho, kodwa kulokhu - ivuliwe isigxobo kwendawo.

Zonke ezinye nemisebenzi zobuchwepheshe kunqunywa injongo yawo. I eziphambili kakhulu futhi usizo lungisa ukukhumbula imizila kweshumi angamakhulukhulu angabanjwa, ukukala ibanga nesivinini, ukubala izinyathelo ezithathwe, kanye kanye kilojoule eyayishiswa ngesikhathi esifanayo. Nokho, iqiniso liwukuthi, kungcono ngisho ikhampasi, navigation.

Bese kuthi-ke okwesibili kubalulekile ukucacisa kokuphetha ngokuthi ikhampasi digital onawo engqondweni. Njengoba kukhona amadivayisi usebenzisa i-Orientation ezimbili-eksisi resistors kazibuthe. Ngomqondo onabile, zingabantu - Ikhampasi efanayo Classic, eqinisekisa isiqondiso izinti Amandla kazibuthe omhlaba. Yonke imiphumela.

Kodwa, abathandi izinto electronic abathandekayo, wenzani uma yonke imishini kukadoti noma baphelelwe amandla? Akusizi kuleli cala ubudala ikhampasi yakho okuhle kazibuthe?
