Nii riigid kui \u00fcksikisikud kasutavad odavaid kuid j\u00e4rjest keerukamaid elektroonilise s\u00f5japidamise s\u00fcsteeme, peamiselt droonir\u00fcnnakute nurjamiseks ja nutulaengute nullimiseks, kirjutab The Wall Street Journal.<\/p>\n
M\u00f5ned segajad, mis v\u00f5ivad summutada suhteliselt n\u00f5rgad GPS-signaalid satelliitidelt 20 000 kilomeetri k\u00f5rgusel orbiidil, on nutitelefoni suurused ja maksavad alla 100 dollari.<\/p>\n
Segamine on m\u00f5nda aega olnud tavan\u00e4htus Venemaa ja Ukraina piirialadel, kuid n\u00fc\u00fcd kannatab selle all Hormuzi v\u00e4in, mille kaudu liikus 20 protsenti maailma naftat.<\/p>\n
P\u00f5hja-Euroopas on lennujaamade l\u00e4histel segatud signaalide t\u00f5ttu suunatud tagasi reisilennukeid. \u00dchel puhul tuli alternatiivsele lennuv\u00e4ljale l\u00e4kitada teraslind, mis k\u00e4tkes Euroopa Komisjoni presidenti.<\/p>\n
Kongressile esitatud dokumendi kohaselt langes Ukrainas 70 protsendilt 6 protsendile \u00fche USA satelliitjuhitud relva tabamusm\u00e4\u00e4r \u2013 p\u00e4rast seda, kui Venemaa v\u00f5ttis kasutusele laiap\u00f5hjalise GPS-segamise taktika.<\/p>\n
Paljud riigid on l\u00e4inud ka GPSi lollitamise teed, saates eetrisse libasignaale.<\/p>\n
Paljud finants- ja sides\u00fcsteemide pakkujad, lennuliinid ja teised elut\u00e4htsad teenused otsivad usaldusv\u00e4\u00e4rseid asemikke. Insenerid on m\u00f5nede kallal aastaid vaeva n\u00e4inud ja need on kas kasutuses v\u00f5i selle veerel.<\/p>\n
Raketijuhtimine miniatuuris<\/p>\n
Juba enne GPS-satelliitide v\u00f5rgu tekkimist maakera \u00fcmber vajas USA kaitseministeerium viisi, kuidas garanteerida ballistiliste rakettide tabamist\u00e4psust. Insenerid otsisid lahendust varajastes rakettides kasutatud inertsip\u00f5hisest navigatsioonis\u00fcsteemist.<\/p>\n
Kasutama hakati g\u00fcroskoope, et m\u00f5\u00f5ta kiirendust ning m\u00e4\u00e4rata selle muutused arvuti abil. Kui s\u00fcsteem teab stardipositsiooni kaardil ning v\u00f5tab arvesse tegurid nagu tuule jms, saab ta asukoha paika m\u00e4rkimisv\u00e4\u00e4rse t\u00e4psusega.<\/p>\n","protected":false},"excerpt":{"rendered":"Nii riigid kui \u00fcksikisikud kasutavad odavaid kuid j\u00e4rjest keerukamaid elektroonilise s\u00f5japidamise s\u00fcsteeme, peamiselt droonir\u00fcnnakute nurjamiseks ja nutulaengute nullimiseks,…\n","protected":false},"author":2,"featured_media":125324,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[80],"tags":[26,27,37,33,35,34,36,31,32,12321,21,28,29,95,19,25,23,24,22,20,30,92,93,94],"class_list":["post-125323","post","type-post","status-publish","format-standard","has-post-thumbnail","category-maailm","tag-breaking-news","tag-breakingnews","tag-ee","tag-eesti","tag-eesti-keel","tag-estonia","tag-estonian","tag-featured-news","tag-featurednews","tag-gps","tag-headlines","tag-latest-news","tag-latestnews","tag-maailm","tag-news","tag-populaarseimad-lood","tag-top-stories","tag-topstories","tag-uldised-uudised","tag-uudised","tag-viimased-uudised","tag-world","tag-world-news","tag-worldnews"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@ee\/116204030165491143","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/posts\/125323","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/comments?post=125323"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/posts\/125323\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/media\/125324"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/media?parent=125323"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/categories?post=125323"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/tags?post=125323"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
