Yintoni iintlobo ze-autonomous tractors, i-high-speed trading, i-Amazon delivery, i-airline schedules, i-power grids, i-Uber rides, kunye ne-blue dot yefoni yakho? Zonke ziquka i-signal ebandayo, ebandayo kwi-12,550 iiyunithi ephezulu kweZizwe, ifumaneka kwi-power level ebandayo, i-engineer eyaziwa "Iinxalenye yesigidi yeemilionth of a billionth of a watt." Yintoni i-GPS. Kwakhona, ngoko kunokwenzeka, i-single point of failure yehlabathi yesimanje. I-Infrastructure ye-Critical ye-You've Never Thought About Xa i-GPS yasungulwa ngo-1995, i-miracle ye-military ingenuity. Namhlanje, i-GPS ibekwe ngokucacileyo kwiinkqubo ezininzi ze-civil. Finance: I-Stock exchanges iintengiso ze-timestamp usebenzisa i-GPS. Umthamo: Iinkqubo ze-power grids zihlanganisa ixesha le-GPS ukuba ziyafumaneke. I-Agriculture: Ukusetyenziswa kwe-precision farming isebenzisa i-GPS ekubeni kunye nokukhula. Telecom: Iintambo ze-cell usebenzisa i-GPS ukuqhagamshela izignali kwi-networks ye-4G kunye ne-5G. I-Logistics: Ukucaciswa kwePakethe, Ukucaciswa kweFlothe, kunye ne-time yokuthumela? Zonke i-GPS. Kwimeko, i-London Economics ibekwe ukuba ukususela ngokupheleleyo kwe-GPS kunokuhlawula i-US Economy ngaphezu kwe-$1 billion ngosuku. Oku ayikho i-typo. Kuyinto i-ticking time bomb. Oregon: Lost in the Snow, Guided by GPS Nceda siqonde oku kwi-example yehlabathi - ngqo. KwiNovemba 20, 2024, amahora angama-20 e-Oregon ziye zithunyelwe nge-GPS ukusuka kwi-I-84 kunye neRuckle Road, i-rute ye-forest service ebizwa ngokuba yi-great snow ngeveki. Zonke iifowuni ze-20 ziye zithunyelwe. Abaninzi abahambayo baye ziye ziye ziye ziye ziye zibonise i-satellite SOS to be rescued (MSN). I-GPS waza wathi. Ukukhusela kwinkqubo ye-navigation iye yaye yaye yaye yaye ngexesha elide - kwaye ngexesha elide. Xa i-Sky Gets Dark Ngiyafikelela njani ukuba i-GPS ayikwazi ukuqhagamshelane ngokufanelekileyo - uya kutyusa ngokupheleleyo. Ndingathanda i-glimpses xa: Kwi-May 2024, i-solar storms iye yenza iingxaki ze-GPS kulo lonke iMidwest ngexesha lokuvelisa. Iintractors ezihlangene kunye neentliziyo ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye ziye zibe. Kwi-Eastern Europe, izigidi ezininzi ze-aircraft zangaphindwe kunye neengxaki ze-spoofing, zihlanganisa iingxowa, iingxowa ze-aborted, kunye neengxaki ze-safety yeemigodi (i-Wired). I-IATA lithunyelwe ukwandisa i-65% yeengxaki ze-GPS kwi-2024 phezu kwi-2023. Ziziphi na iingxaki ze-Blips ze-statistical. Ziziphi na iingxaki ze-advertising. Ukushicilela Solar Yintoni iinqwelo ezininzi kunye ne-tractors Thina siphile: Yintoni i-GPS ye-disconnect ye-GPS eyenza kwiinkalo ezininzi? Ukuhambisa: Izindiza ziye zithunyelwe. Izibane zeTraffic zithunyelwe. Iiplatforms ze-Rideshare zithunyelwe. Iinkonzo zokuthunyelwa zithunyelwe. I-Telecom: Iinkonzo ze-cellular zihlanganisa. Isantya se-Internet isaphantsi. Iinkonzo ze-emergency ayikwazi ukufumana abathengi. Iimali: izindlu ze-trade zihambe. I-timestamps iye haywire. Ukuhlaziywa kwe-fraud ibonakaliswa. I-Power Grids: I-Generators ifumaneka kwi-phase. I-Blackouts ifumaneka kwi-regionally. I-Supply Chains: I-Inventory Tracking Systems ifumaneka. I-Ports, i-Trucks, kunye ne-Retailers ziya kuxhomekeke kwi-Chaos mode. Ukusabela Ukusabela Ukusabela Ukusabela Ukusabela Ukusabela Ukusabela Ukusabela Ukusabela Ukusabela Ukusabela Ukusabela Ukusabela Yonke ngenxa enye ingxelo eluhlaza, esifutshane, unencrypted, amandla eliphantsi. Yintoni hhayi kuthatyalaliswa oku? Umbuzo Great. I-U.S. Department of Transportation yenzelwe ukwakha inkqubo ye-GPS backup ngexesha elide ngo-2004. Kwixesha elide: izivumelwano ezininzi, ama-memos, kunye ne-executive orders. Kodwa akukho i-backup eyakhelwe. Ngexesha elide, amazwe afana neChina zinezinto ezintathu: BeiDou (i-space), i-fiber-optic timing, kunye ne-eLoran (i-radio). KwiRashiya i-GLONASS kunye ne-CHAYKA. I-US.? Kwakhona i-National PNT Advisory Board yeTshayina White wamkelwa ngexesha elidlulileyo ukuba iinkqubo yaseMelika ye-GPS ye-resilience "ukubonisa okanye i-priority ebonakalayo ye-system, okanye i-accountability ebonakalayo" (i-Breaking Defense). I-Illusion ye-redundancy Yes, iinkqubo ezininzi ukuba bafumane i-backups - kodwa ama-backups ezininzi ziquka kwi-GPS yokubhalisa okanye engabonakali kakhulu ukusetyenziswa okuqhubekayo. Ukucinga Ngokwesibonelo, iifowuni ingaba ama-sensors ze-inertial (i-gyroscopes kunye ne-accelerometers), kodwa abaqhelekanga ngokukhawuleza. I-aeroports ingasebenzisa ama-beacons zendawo, kodwa ngaphandle kwe-timing esekelwe kwi-GPS, ukuxhaswa kwabo kunye ne-system ye-national. Njengoko uphando ka-GPS World ngo-June 2024, kuphela ama-aerodroms eziqhelekileyo kunye ne-AltPNT (njenge-DFW kunye neDenver) bakwazi ukugcina ukusebenza ngexesha le-GPS. Yintoni ndingathanda? (ngoku) Nazi iindaba elungileyo: Akukho kufuneka ukhangele umdla. Singakwazi ukwenza. Ukusetyenziswa kwe-eLoran – Umgangatho we-timing kunye ne-nav ephakamileyo, ebonakalayo. Kwakhona kusetyenziswa eChina kunye neRashiya. I-Fund quantum timing research - Njengoko i-National Timing Centre ye-UK ibekwe ukuvelisa i-satellite-free timing ehlabathini lonke (IoT World Today). Yenza iintlobo ezahlukeneyo ze-AltPNT - i-Fiber timing, i-M-GPS®, i-AI visual systems kunye nokunye. Ukukhuthaza ulwazi lwabathengi – GPS ayikho kuphela ibhodi yeefowuni yakho. Yintoni isakhiwo seCivilization. Qhagamshelane njenge. Ukuvunwa kwe-resiliency testing – Ukuvunwa zonke abasebenzi be-infrastructure ezibalulekileyo ukuba zibonise izifundo ze-”day without GPS”, njengoko i-Air Force isebenze. I-Coordinates yeMphathiswa Sithuba ekhaya kwi-GPS house yeenkcukacha. Kwaye umoya uhamba. Ukuba ukhangela oku kwi-smartphone yakho, ufunde oku: iitebhasi yakho, iitebhasi yakho, imali yakho, amandla yakho - zonke zithunyelwa nge-spectra signal ukusuka kwihlabathi ukuba nayiphi na umntu ngeentlobo emininzi kunye neengxaki. Ixesha lokugqiba ukuba i-GPS iya kuba njalo - kunye nokufaka ukuyila ngosuku. **Ukuba le ngosuku ayikho ngexesha elidlulileyo. Kubonakala, isikhwama isikhwama, isikhwama isikhwama, isikhwama isikhwama.
