Zog ntawm Guj kuj txuas ntxiv nws cov kev sim kom jam satellite navigation systems tom qab lub drone nres ntawm Engels Airbase thaum lub Kaum Ob Hlis 5th. Qhib cov ntaub ntawv qhia qhov loj ' npuas' ntawm jamming signals nyob ib ncig ntawm Moscow thiab ntau lub hom phiaj muaj peev xwm, suav nrog Engels airbase. Txawm li cas los xij, qhov no zoo li tsis muaj txiaj ntsig rau qhov kev tawm tsam tshiab drone ntaus lub airbase dua Hnub tim 25, tsis ntev tom qab lwm cov drones tsom lub Crimea.
Raws li satellite navigation tus kws tshaj lij Dana Goward, Thawj Tswj Hwm ntawm Resilient Navigation thiab Timing Foundation, Russia feem ntau tso siab rau hom jamming los tawm tsam ntev-ntev kamikaze drone tawm tsam. Thaum lub sijhawm luv luv drones feem ntau yog nyob rau hauv kev tswj hwm tus neeg teb xov tooj ncaj qha, kev tawm tsam ntev ib-txoj kev feem ntau cia siab rau GPS lossis lwm yam satellite navigation. Jam GPS thiab lub drone poob khiav ntawm qhov chaw nws yog; nws yuav ua tau tej yam kev puas tsuaj tab sis muaj tsawg lub sij hawm los tsoo lub hom phiaj.

Lub Engels airbase yog ib co 400 mais ntawm ciam teb nrog Ukraine thiab hosts Russia lub ntev-ntau aviation bomber rog; thaum lub sij hawm kawg ib tug xov tooj ntawm aircraft tau puas. Cov yeeb yaj kiab los ntawm sab nraud ntawm airbase ntawm 25th qhia qhov tawg ntawm qhov chaw tab sis tsis muaj pov thawj ncaj qha ntawm qhov tshwm sim. Cov tub ceev xwm Lavxias hais tias lawv tua cov drone tawm tsam uas tom qab ntawd tsoo rau hauv ib lub tsev, tua peb tus tub rog.
In cais qhov xwm txheej, Lavxias teb sab chaw hais tias xya drones launched los ntawm Odessa tawm tsam lub hom phiaj nyob rau hauv lub Crimea. Ib zaug ntxiv, cov neeg Lavxias hais tias txhua tus neeg tawm tsam raug tua, tab sis tsis muaj txoj hauv kev los txheeb xyuas qhov no. Qhov chaw hais los ntawm tus kws tshuaj ntsuam Sam Bendett, nco ntsoov tias cov drones muaj peev xwm khiav tawm cov tshuab hluav taws xob ua tsov rog thiab yuav tsum raug tua.
Qhov xwm txheej zoo sib xws rau txuas ntxiv kev tawm tsam drone los ntawm Iranian-muab Shahed-136s ntaus Ukrainian fais fab infrastructure: qeeb, nqi qis drones uas yog siv tau vim hais tias lawv muaj peev xwm raug launched nyob rau hauv loj thiab txaus los mus ua tej yam kev puas tsuaj.
GPS jamming feem ntau tsuas yog siv tau raws li kab-ntawm-pob qhov muag, yog li lub drone ya qis tsuas tuaj yeem cuam tshuam los ntawm qhov deb deb. Drones zoo li Shahed-136 nqa ib qho inertial navigation unit, ib tug thaub qab system uas tsis cia siab rau satellite signals. Cov 'drift' thiab sai sai poob qhov tseeb, yog li lawv tsis muaj txiaj ntsig zoo li GPS rau lub luag haujlwm ntev, tab sis yuav tsum ua haujlwm zoo txaus rau lub drone los ua kom nws los ntawm kev sau luv luv ntawm jamming. Thaum feem ntau Shahed-136s raug coj los, qhov no zoo li yog los ntawm rab phom los yog missiles tsis yog jamming. Nws zoo nkaus li tias Ukraine tau siv cov txuj ci zoo sib xws hauv nws tus kheej kev tawm tsam drones.
Cov koom haum koom nrog hauv Crimea nres tau hais tias yog raws li Suav Mugin-5 kev lag luam drones, raug nqi ib ncig $10k txhua - yog li nws kuj tseem pheej yig dua li Shahed-136s, thiab pheej yig dua li cov cuaj luaj xav tau los tua lawv.
Russian jamming yog tau txais txiaj ntsig nrog kev tshem tawm ntau ntawm Ukrainian drones thaum pib ntawm kev tsis sib haum xeeb, txawm tias qhov no yog tsis tau yug los ntawm cov duab ntawm cov khoom siv tiag tiag raug rhuav tshem, thiab tseem muaj cov duab ntawm drones bombing electronic warfare sites nrog zoo li impunity. Txawm li cas los xij, jamming tsis yog panacea tiv thaiv kev tawm tsam drone uas qee qhov kev cia siab.
Russia tau tshaj tawm pib txav chaw tiv thaiv huab cua nyob rau hauv txoj hauj lwm puag ncig Moscow, thaj ntshai ntawm kev tawm tsam nyob ib ncig ntawm kev ua koob tsheej Xyoo Tshiab. Yog Ukraine npaj ib tug drone Doolittle Raid, cov Russians tsis tuaj yeem cia siab rau jamming ib leeg los tiv thaiv lawv.
Goward hais tias "Ob tog pom tias tsis muaj kev tiv thaiv zoo tshaj plaws," Goward hais.
