Lub Tsev Kawm Ntawv Qib Siab Western Australia's 'TeraNet', lub network ntawm cov chaw kho qhov muag hauv av tshwj xeeb hauv kev sib txuas lus ceev ceev, tau ua tiav tau txais lub teeb liab laser los ntawm German low-Earth orbit satellite. Qhov kev tawg ua rau txoj hauv kev rau 1,000-fold nce bandwidth ntawm kev sib txuas lus ntawm qhov chaw thiab lub ntiaj teb.

TeraNet's laser kev sib txuas lus kuaj nrog OSIRISv1 cim ib kauj ruam tom ntej rau Western Australia hauv kev hloov cov xov tooj cua tshaj tawm nrog cov lasers ceev hauv qhov chaw sib txuas lus. Nyiaj txiag los ntawm Tsoom Fwv Australian, lub network tau tsim los txhawb ntau lub luag haujlwm thiab txhim kho cov ntaub ntawv muaj peev xwm kis tau thoob plaws ntau qhov chaw.
Pab pawg TeraNet, coj los ntawm Associate Professor Sascha Schediwy ntawm University of Western Australia node ntawm International Center for Radio Astronomy Research (ICRAR), tau txais cov teeb liab laser los ntawm OSIRISv1, laser kev sib txuas lus them nqi ntawm German Aerospace Center's (DLR) Lub Koom Haum rau Kev Sib Txuas Lus thiab Navigation. OSIRISv1 yog mounted ntawm University of Stuttgart's Flying Laptop satellite. Cov teeb liab tau kuaj pom siv ob lub TeraNet kho qhov muag hauv av chaw nres tsheb thaum lub sij hawm ya ntawm satellite hnub Thursday kawg.
"Qhov kev ua qauv qhia no yog thawj kauj ruam tseem ceeb hauv kev tsim kom muaj kev sib txuas lus chaw txuas ntxiv mus hauv Western Australia. Cov kauj ruam tom ntej suav nrog kev txuas lub network mus rau lwm qhov chaw kho qhov muag tam sim no tau tsim hauv Australia thiab thoob ntiaj teb," Associate Professor Schediwy tau hais.

TeraNet cov chaw nres tsheb hauv av siv lasers, es tsis yog cov xov tooj cua wireless ib txwm siv, xa cov ntaub ntawv ntawm satellites hauv qhov chaw thiab cov neeg siv hauv ntiaj teb. Vim tias cov lasers ua haujlwm ntawm ntau zaus ntau dua li xov tooj cua, cov ntaub ntawv tuaj yeem xa mus rau ib thib ob tuaj yeem muaj peev xwm siab li 1,000 gigabits.
Wireless xov tooj cua tshuab tau siv rau qhov chaw sib txuas lus txij li thaum lub community launch ntawm thawj satellite satellite, Sputnik 1, ze li ntawm 70 xyoo dhau los, thiab cov thev naus laus zis tseem tsis tau hloov txij thaum ntawd los. Raws li tus naj npawb ntawm satellites nyob rau hauv qhov chaw nce, thiab txhua lub satellite tshiab tsim cov ntaub ntawv ntau dua, qhov tseem ceeb hauv lub qhov chaw tam sim no tau tshwm sim los ntawm kev tau txais cov ntaub ntawv rov qab rau lub ntiaj teb.
Laser kev sib txuas lus zoo haum rau kev daws qhov teeb meem no, tab sis qhov downside yog tias laser teeb liab tuaj yeem cuam tshuam los ntawm huab cua thiab nag. Pab pawg TeraNet tab tom txo qhov tsis txaus no los ntawm kev teeb tsa lub network ntawm peb lub chaw nres tsheb hauv av kis thoob Western Australia. Qhov no txhais tau hais tias yog tias ib qho chaw nres tsheb hauv av yog huab, lub satellite tuaj yeem rub tawm cov ntaub ntawv mus rau lwm qhov chaw nres tsheb hauv av uas nws tshav ntuj.
Tsis tas li ntawd, ib qho ntawm ob lub TeraNet hauv av chaw nres tsheb uas tau txais satellite lub teeb liab laser yog tsim nyob rau sab nraum qab ntawm lub jeep tsim. Qhov no txhais tau tias nws tuaj yeem xa mus sai sai rau qhov chaw uas xav tau kev sib txuas lus ceev ceev, xws li cov zej zog nyob deb tau txiav tawm ntawm kev sib txuas lus ib txwm muaj los ntawm kev puas tsuaj ntuj tsim.
Kev kub ceev laser kev sib txuas lus los ntawm qhov chaw yuav hloov pauv cov ntaub ntawv xa mus los ntawm lub ntiaj teb soj ntsuam satellites, txhim khu kev ruaj ntseg ntawm kev sib txuas lus tub rog, thiab txhawb kev nyab xeeb kev ua haujlwm nyob deb hauv cov haujlwm xws li kev ua haujlwm mining autonomous, nrog rau kev npaj kev puas tsuaj hauv tebchaws thiab teb.
Pab pawg TeraNet ntawm ICRAR tau txais nyiaj los ntawm Australian Government, Western Australian Government thiab University of Western Australia hauv 2023 uas yog ib feem ntawm Australian Space Agency's "Moon to Mars Demonstration Mission" kev pab nyiaj. Txoj haujlwm $6.3 lab txhawb nqa kev tsim kho ntawm peb TeraNet kho qhov muag hauv av chaw nres tsheb hauv Western Australia, nrog rau German Aerospace Center (DLR) muab nws cov satellite hauv-orbit nruab nrog cov khoom siv sib txuas lus laser hauv hom.
TeraNet yuav txhawb nqa ntau qhov chaw ua haujlwm thoob ntiaj teb kev ua haujlwm ntawm lub ntiaj teb qis thiab lub hli, siv ob qho tib si cov qauv kev sib txuas lus kho qhov muag thiab cov thev naus laus zis zoo tshaj plaws, suav nrog kev sib txuas lus hauv qhov chaw sib sib zog nqus, kev sib txuas lus ultra-high-speed coherent, quantum ruaj ntseg kev sib txuas lus, thiab optical positioning thiab sij hawm.
Lub network muaj xws li chaw nres tsheb hauv av ntawm University of Western Australia, qhov chaw nres tsheb hauv av thib ob ntawm Mingenew Space Precinct, 300 mais sab qaum teb ntawm Perth, thiab lub chaw nres tsheb hauv av tau ua haujlwm ntawm European Space Agency lub chaw tshiab Norcia.
