Kuphi kufanele usebenzise i-GPS jammer yendrone ukulawula ukuthi kusebenze ngempilo?

Ukuthi I-Jammer Yokugcina i-GPS Yendrone Iyakhubaza Iindrone Ezingavumelekileyo

Ukukhubaza Isignali Yokuqondisa i-GNSS: Ukukhubaza i-GPS, i-GLONASS, ne-Galileo Ukuze Kuvalelwe Ukuphatha Ukuphatha Kwezindawo

Iindrone ezingavumelekileyo ziyasebenzisa ngokupheleleyo i-Global Navigation Satellite Systems (GNSS)—kubandakanya i-GPS, i-GLONASS, ne-Galileo—ukufaka izindawo, ukugcina ubude bokwesibhakabhaka, nokuphatha ngokwesibhakabhaka. I-jammer yokugcina i-GPS yendrone iyasebenzisa le ndlela yokusebenza ngokuthi iyathumela isithunzi esikhulu sesithunzi sokuhlanganisa ngaphakathi kwezinye zezindawo zokugcina i-GNSS (kakhulu 1.227 GHz ne-1.575 GHz), okuyikhubaza isignali esincane sasezinkampani ezihlanganiswayo esifundwa ngumshini wendrone wokugcina. Lokhu kukhindza ukuthi kwenziwe ukubala kwezindawo ngokucophelela futhi kuvuleka ukungafani kwezinhlelo zokusebenza ngokushesha:

• Ukudlula kwendawo: Ukungabonakali kwezindawo zokugcina kuzoba nesiphumo sokudlula ngokungafani noma ukungafani kokuhlala emhlabeni
• Ukukhuphuka kwe-Navigation: Imisebenzi yezindawo eziphakathi zikhubazeka; izinkundla zokubuyela ekhaya (RTH) ziphulula noma zihlukaniswe
• Ukwenza ukuthi isimo sokubuhlungu sivulekile: Izidrone zonke zokusebenza ngendlela yokuziloba nezodlame zingakhetha ukuthi zihlale phansi, ukulanda kwesikhathi esiphambili, noma ukubuyela ngendlela engeziwe

Le ndlela iyasebenza kakhulu ngaphezu kwezidrone ezitholakala ngokuzenzekelayo enenani elincane lezinhlobo—ukuvimba izinkinga ngaphezu kwezindawo zezingu-100–500 mete, kusukela ku-ouput yomshayeli wokuvimba, isiqhameko isimo sokwakha, nemizamo yezindawo njengokugcina kwezindawo zokuziloba noma ukugcina kwezindawo zokuziloba.

Ukuthamela Kweminyathelo Yezindawo Ngokweminyathelo Yezidrone Zokuziloba Nokubuhlungu Kwezindlela Zokubuhlungu

Izidrone zezintandokazi zimanje zinamaphuzu okubuhlungu—kufaka ukuthamela kwezindawo zokuziloba (FHSS), izinkundla zokuziloba eziphathelwe ngokuphatha, namabhalo amanjiwe ayezindawo zokuziloba—ukubhekana nokuvimba okungavumelekile. Ukubhekana nalo, izidrone zokuvimba kwe-GPS zezintandokazi zokuziloba zinamaphuzu okuchaza ispekthremu ngokushesha nokuthamela ukuthamela okuvumelana. Ngemizuzwana eminye yokuqondwa kokuthi izidrone ziyathola isigaba sokuziloba, zibeka ukuvimba okuvumelana ngaphezu kwe:

• Izindawo zokuziloba: Ukujama kwe-GPS L1/L2, GLONASS G1, nokwe-Galileo E1 ngokufanayo
• Izindawo zokulawula: Ukuthinteka kokugcina okuhambisana nezindawo zokulawula ze-2.4 GHz ne-5.8 GHz
• Ukuzilungiselela ngokutshona: Ukubuyisela kakhulu ukusukela ekuvumelweni kwe-FHSS noma ukuguqula phakathi kwezindawo zokulawula zezinhlangano zezinkambo zokuphatha izinkambo (GNSS)

Lokhu ukuzilungiselela kungavimbi ukubuyisa kwezinkambo zokuphatha izinkambo (inertial navigation) noma ukubuyisa kwezinkambo zokubona (visual odometry) ngeminyaka yokuqala yokungafanele—futhi kungavimbi izidwaba ukubuyisa kwezinkambo zokuphatha izinkambo (backup protocols). Ngokubhalwe ngu-Ponemon Institute ekubhalweni kwakhe we-2023 UAS Security Assessment, “93% yezidwaba zokusebenza ngokomlando zibuyisa kumodi yokuqhandwa lapho i-GNSS ingafanele,” okwenza isikhathi esikhulu sokuthinteka kwezindawo zokuphatha izinkambo (operator disorientation) nokuthinteka kwesithunzi (physical interdiction). Ukusebenza kahle kungabikho ngokwesifundiswa sokubhala (brute-force broadcasting), kodwa ngokwesifundiswa sokubhala esihambisana nesimo (intelligent, context-aware signal suppression).

Izindlela zokuphatha esivumelweyo zokubhala izidwaba zokuphatha i-GPS

Ukuvikela izinkambo ezingcono kakhulu kusuka kwezindlela zokubona noma ukuthumela izinto eziningi

Izikhishimiso zesithunzi, izindawo zokuchitha amanzi, nezindawo zokugcina idatha zihlwa ngamathuba okukhombisa kwe-drone nokuthumela izinto ezingavumelekile. Kulezi zindawo, i-jammer yase-GPS yase-drone inikeza indlela eyengeziweyo yokubulunga ukuthula kwesikhathi esingavumelekile ngaphambi kokukhombisa noma kokuthumela. Ngokuvimbela ukuthola kwe-GNSS, iyabulunga ukuthula kwe-drone ukuze libeke kulesi sikhundla noma libuyele ekhaya lalo, ngaphandle kokuthwala amazwi okuhlonipha noma kokuthiwa kwezinto zokuphatha. Uma ibhalwe ngamandla amanqambu amanqambu nezinhlobo zokubalwa kwamandla, ukubulunga kungakhiywa kumiphakathi yezindawo, okufaka isibonelo sokubulunga kwezindawo ezinye noma abasebenzi bese-GNSS basebantwana.

Ukuvikela Isikhumbuzi Esedlakini Kwesikhumbuzi Sesihlwayo, Izindawo Zasegoverenment, Nezindlela Eziningi Zokuhlola Abantu Abanamandla

Amaphutha amadala asebenza kwi-GPS esingathwaliyekile ukusebenzisa izindikimba zokufika ngokuphelele njenge-WAAS ne-GBAS; ukugcina kwe-GNSS ngendlela efutshane kuyakwenzela imizimbi eminingi yokuphila. Ngokufanana, amaphutha amadala amagovrenment nezindlela ezingaphakamile ziyabulawa ngamadroni okukhombisa okungafanelekile noma okubhekisekile kumzimbi. Umkhombisi we-GPS wamadroni uyakwenza indawo engavunyelwanga yokuqonda ngokuxhaswa ngokuphansi kokuthi akhangelelwe ukusiza kwesikhathi esifutshane—okuzosika amadroni ukukhangelela isikhundla, ukuvula izindlela zokusebenza, noma ukususa kwezindawo ezisondwe. Ngokulingana ngezinkokhelo zokuphinda, akasiza ukuthi kwenzeke ukuthwala kwezinto, futhi akasiza imizimbi yezinhlelo zokuphatha okuhambisana nokuphatha kwesikhathi sokuphatha kwezindawo zokuphatha, okusiza ukuthi kwenziwe ngokuphelele kwezindawo zokuphatha ezinamandla apho ukuphila nokuphatha kwezinhlelo zokuphatha kuyisisekelo esiphakeme.

Izindima zokuphatha nokuziqonda izimizimbi zokusebenzisa umkhombisi we-GPS wamadroni

FCC, ITU, nezinhlelo zokuphatha zaseNingizimu Afrika zisilisa ukusebenzisa umkhombisi we-GNSS kwezindawo zokuphatha

Ukusebenzisa i-GPS jammer yezindiza ngokwesibonelo kuzokwenzeka ngokungafanelekile kuwo wonke amadoda. Kwe-United States, i-Federal Communications Commission (FCC) isiqinisekisela ngokuphelele ukuthi akukho ukubambisana okwenzekile ngokwesibonelo ngezinhlangano zokuhlanganisa izinkambo zokuhlanganisa ngaphansi kwe-Section 333 yokuqondisa kwemithombo yezinkambo—kuyabambisana ngokuphelele imali yokubambisana engaphezulu kwe-$100,000 ngalokho okwenzekile. I-International Telecommunication Union (ITU) iyakhipha ukubambisana kwe-GNSS njengokuthi kuyakhiwa ngokungafanelekile ukuthi kubambisana ngezinhlangano zokuhlanganisa, futhi abaphathi besebenzisa izinhlangano zokuhlanganisa—kodwa kufuneka kubhekwe e-Ofcom (UK), BNetzA (Germany), ne-ACMA (Australia)—bavumela ukuthi kubambisane ngokufanayo. Kunezindlela ezifanayo kuphela kubasebenzisi abavunywe: izinsizwa zokuphatha izinsizwa, izihlombe zokuphatha izinsizwa zokuphatha zokuphatha ngokwesibonelo sokuphatha, noma abasebenzisi bezinhlangano ezikhulu abavunywe ngokuphelele ukuthi babambisane ngokwesibonelo sokuphatha ngokwesibonelo sokuphatha.

Ukuthi kubambisana kwezinhlangano zokuphatha izinsizwa, ukuphatha izinsizwa zokuphatha, nokubambisana kwezinhlangano zokuphatha ezingaphakade

Amajamme e-GPS ase-droni ayenza izinhlayiya ze-RF ezingavamile okungakhathali kwezinye izindawo ezibalulekile ngaphandle kwezinye ezithakelwe. Amakhompyutha e-aviation esebenzisa izinkundla zokufunda i-GPS—kukhona izi-transponder ze-ADS-B nezindlela zokufunda e-RNP—ziyathakelwa ukuthi isinyathelo sesinye siphinde sifanele. Abasemthwakini abasebenzisa izi-radiyo ezenziwe ngokusebenzisa i-GNSS noma izisayensi zezikhospital ziyathakelwa ukuthi isinyathelo sesinye siphinde sifanele noma isikhundla asizange sibonakaliswe kahle. Kusenziwe kwesikhathi esithi 2023 emkhambini we-Guizhou, kwalokho kwenziwe ukuthi kubekhala ukuthakatha kwezinhlayiya zokuphatha amakhompyutha e-aviation emkhaya wokuphatha kahle kusukela ku-90 minithi, okuvumela ukuthi kubekhala ukuthakatha kwezinhlayiya zokuphatha amakhompyutha e-aviation kusukela ku-$740,000. I-Ponemon Institute’s 2023 UAS Risk Report iyavuma ukuthi ukuthakatha kwezinye izinhlayiya kuyisibopho esibalulekile kakhulu sokuthakatha okungasalwa—okuvumela ukuthi abasebenzisi bakhululekwe kubukho kwezinkinga zokuthakatha, ukuthakatha kwezinhlayiya zokuphatha, nokuthakatha kwezinye izinhlayiya zokuphatha uma izinhlayiya ezingathakelwe zihlala kusukela ku-ukuthakatha noma izinkinga zokuphatha.

I-Jammer ye-GPS yase-droni vs. Izindlela ezingafaniyo zokuphatha i-UAS: Lapho kuyisikhundla esihle

Ukukhetha i-jammer ye-GPS yendrone kufanele ikhombise isimo sesiqondiso, indawo, nokuthintana nesifundo sokuziphatha. Isiphezi sakho sikhona ekupheleni kwakho kokubambisana ngokushesha, ngaphandle kokusebenzisa amandla okuphuma, kwezindwendwe zokubambisana kwe-GNSS—okukhuluma ukulanda kwezindwendwe ngokuphelele noma ukubuyela emuva (RTH) ngaphandle kokuthintana nendlela yokuphuma. Lokhu kuyasebenza kakhulu kumathuba awaphansi, apho izindwendwe ezingcono kakhulu ziyabamba, apho izindwendwe ezisemthwakweni ziyathintana nokuthintana nokubonakaliswa kwezindwendwe noma ukubonakaliswa kwezindwendwe. Kepha, ukusebenza kuyadlula phambi kwezindwendwe ezinamathuba okusebenzisa i-inertial measurement units (IMUs), i-visual odometry esebenzisa i-AI, noma izindwendwe ezisebenzisa izinhlangano zezindwendwe eziningi—ukungathi zihambaniswe nezindlela zokuvumela nokuvumela kwe-RF.

Isistrategi esihle sekubambisana nezindiza zokusebenza ngokwesibonelo isebenzisa indlela eyodwa: ukubambisana ngokwesibonelo esikhona konke, ukubambisana ngokushesha, nokubambisana ngokwesibonelo esifanayo—kukhulula ukubambisana ngokwesibonelo lapho kuvunyelwe ngokwesibonelo. Izijamme ziyabuyela emthethweni wokubambisana ngokwesibonelo lapho zisebenziswa ngokwesibonelo kodwa ukusebenzisa kuzodinga ukubonwa ngokwesibonelo, ukubonwa ngokwesibonelo lwesayensi, nokubambisana ngokwesibonelo lwesayensi.
