Key Takeaways
- Cov kws tshawb fawb tau los nrog lwm txoj hauv kev siv cov tshuab quantum es tsis siv GPS.
- GPS cov tshuab tuaj yeem kaw lossis tsis muaj.
- Qee lub tsheb uas muaj kev ywj pheej tuaj yeem taug kev siv qhov pom kev pom los ntawm lub koob yees duab, radars, thiab lidars cuam tshuam nrog cov ntaub ntawv qhia chaw.
Koj tsis ntev yuav tsis xav tau GPS nrhiav koj txoj hauv kev.
Ntiaj teb no positioning systems (GPS) tau dhau los ua ubiquitous nyob rau hauv txhua yam ntawm xov tooj mus rau lub tsheb. Tab sis cov kws tshawb fawb tau los nrog ib txoj kev tshiab uas siv quantum mechanics kom taug qab cov lus qhia es tsis txhob siv satellite network.
"Muaj ib lub sijhawm uas GPS tsis muaj," Sandia National Laboratories kws tshawb fawb Peter Schwindt hais rau Lifewire hauv kev xam phaj email. "Tej zaum koj nyob hauv thaj chaw uas koj tsis tuaj yeem tau txais GPS, xws li hauv nroog canyon lossis lub qhov. Tsis tas li ntawd, GPS tau yooj yim jammed. Yog li, yog tias cov ntawv thov tsis tuaj yeem zam qhov kev pheej hmoo ntawm GPS tsis muaj, yuav tsum muaj lwm txoj hauv kev."
Ua Haujlwm Nrog Tsis Paub
Schwindt thiab nws cov npoj yaig tsis ntev los no tau piav qhia txog quantum ntaus ntawv hauv ib daim ntawv luam tawm hauv AVS Quantum Science. Nws yog avocado-zoo li gadget nrog titanium hlau phab ntsa thiab sapphire qhov rais uas muaj ib tug huab ntawm atoms ntawm txoj cai tej yam kev mob rau meej navigational ntsuas.
Lub tshuab nqus tsev yuav nkag mus rau hauv atom interferometer, accelerometer, lossis gyroscope. Peb lub high-precision accelerometers thiab peb lub gyroscopes tsim ib chav ntsuas inertial, uas ntsuas me me hloov hauv kev taw qhia.
"Atom interferometer thev naus laus zis muaj peev xwm ua tau lub siab muaj tseeb inertial sensor uas tuaj yeem tso cai rau kev siv sijhawm ntau teev yam tsis muaj kev hloov kho sab nraud yog tias qhov tseeb hauv chav kuaj tuaj yeem txhais ua cov cuab yeej siv tau," Schwindt hais.
Muaj ob txoj hauv kev tseem ceeb ntawm kev taug kev yam tsis muaj GPS, Schwindt tau hais. Txoj kev siv ntau tshaj plaws yog siv lwm cov teeb liab sab nraud kom tau txais cov ntaub ntawv xov xwm, xws li xov tooj ntawm tes teeb liab. Lwm qhov yog siv cov inertial sensors, uas ntsuas qhov acceleration thiab kev sib hloov (xws li, lub tsheb lossis dav hlau) yam tsis tas yuav muaj cov teeb liab sab nraud. Kev ntsuas inertial tau ua tiav tas li txhawm rau muab qhov hloov tshiab tas li rau lub platform txoj haujlwm, kev taw qhia, thiab tshaj tawm.
Robocars Xav Tau Cov Duab Zoo dua
Cov tuam txhab tsheb Autonomous tab tom nrhiav kev rau lawv lub tsheb mus rau qhov tsis muaj GPS. Cov tsheb uas muaj kev ywj pheej no siv cov duab pom los ntawm lub koob yees duab, radars, thiab lidars cuam tshuam nrog cov ntaub ntawv qhia chaw, John Fischer, tus lwm thawj ntawm kev tshawb fawb thiab kev loj hlob ntawm lub tuam txhab navigation Orolia, hais rau Lifewire hauv kev sib tham hauv email.
"Ib yam li koj tsis xav tau GPS tsav tsheb hauv koj lub zej zog-koj muaj cov duab qhia chaw thiab cov duab pom tau khaws cia hauv koj lub hlwb-autonomous nav systems tam sim no muaj cov ntaub ntawv loj loj thiab cov kev pom los siv," nws hais ntxiv. "Ntxiv rau qhov no inertial navigation system-siv gyroscopes thiab accelerometers los ntsuas cov txheeb ze txav-thiab koj muaj kev taw qhia zoo."
Sandia National Laboratories
Rau cov neeg uas yuav tsis tau dhia hauv Tesla, GPS, nws tus kheej, yuav tsum tau hloov kho. Ib tiam tshiab ntawm lub ntiaj teb qis orbit (LEO) satellites twb nyob rau hauv qhov chaw muaj teeb liab mus txog 1,000 lub sij hawm muaj zog nyob rau hauv lub ntiaj teb nto, thiab yuav siv tau raws li lwm txoj rau GPS.
Tsis tas li, qhov tshiab 5G xov tooj ntawm tes yuav muab Kev Pabcuam Qhov Chaw Nyob (LBS) uas yuav ua rau GPS qhov tseeb, Fischer tau hais.
Ib txoj hauv kev uas cov neeg siv tuaj yeem tau txais txiaj ntsig los ntawm lwm txoj hauv kev rau GPS yog txhim kho kev ruaj ntseg, tus kws tshaj lij cybersecurity Magda Chelly hais rau Lifewire.
"Kuv xav tias txhawj xeeb txog daim ntawv thov GPS thiab lub peev xwm los hloov cov ntaub ntawv ncaj ncees lossis hloov lub GPS tiag tiag ntawm lub tsheb lossis lwm yam khoom siv," nws ntxiv. "Peb tab tom pom ntau txhiab daim ntawv thov mobile muab kev pabcuam raws li kev tswj hwm GPS. Txawm li cas los xij, qhov cuam tshuam yog tias GPS kev tswj hwm tuaj yeem raug spoofed yog tias daim ntawv thov tsis siv kev ruaj ntseg zoo."
Txawm tias koj siv GPS, muaj txoj hauv kev los txhim kho kev paub dhau los. Lub tsheb tsav tus kheej tuaj yeem txhim kho nrog kev siv thev naus laus zis, xws li daim ntawv qhia HD uas sib txuas cov lidar thiab optical sensors, Tatiana Vyunova, tus thawj coj ntawm lub tuam txhab ua daim ntawv qhia NTAWM Technologies, hais rau Lifewire.
Atom interferometer thev naus laus zis muaj peev xwm ua tau qhov siab tshaj plaws inertial sensor uas tuaj yeem tso cai rau kev taw qhia rau cov xuab moos yam tsis muaj kev hloov kho sab nraud…
Mercedes-Benz, piv txwv li, siv Here's HD Live Maps ntawm qee lub tsheb, ua rau cov neeg siv "pom dhau" GPS thiab ntau yam ntawm onboard sensors.
"Cov chaw ntxiv ntawm kev nyob hauv cheeb tsam thiab qhov chaw muab cov txheej txheem ntxiv nrog kev ruaj ntseg, kev nyab xeeb, thiab rov ua dua," Vyunova tau hais. "Ib yam ua rau muaj xws li GPS jamming, spoofing lossis teeb liab yuam kev hauv nroog canyons."
