Kev tsom xam ntawm kev siv thiab faib cov 1250mHz zaus band

Lub 1250MHz zaus band nyob rau hauv xov tooj cua thiab tau siv dav hauv teb xws li satellite sib txuas lus thiab kev sib txuas lus satellite. Nws ntev teeb liab kis nrug thiab qis attenuation muab nws tshwj xeeb rau cov txiaj ntsig zoo hauv cov ntawv thov.

Cov chaw thov tseem ceeb:

Satellite sib txuas lus: 1250MHz zaus band yog siv rau kev sib tham ntawm satellites ntawm satellites ntawm satellites thiab chaw nres tsheb hauv av. Txoj kev sib txuas lus no tuaj yeem ua kom muaj kev pab cuam dav dav, muaj cov kev tiv thaiv dav dav, thiab yog cov muaj zog tshaj tawm hauv tebchaws, kev sib txuas lus mobile thiab satellite tshaj tawm xov xwm.

Navigation system: nyob rau 1250MHz zaus band, L2 zaus band ntawm lub ntiaj teb satellite qhov system (Gnss) siv qhov kev ntsuas no kom haum txoj haujlwm thiab taug qab. Gns tau dav siv hauv kev thauj mus los, Aerospace, nkoj thauj khoom thiab kev tshawb nrhiav goological.

Cov xwm txheej tam sim no ntawm Cov Khoom Siv Hluav Taws Xob:

Raws li "xov tooj cua ua ntu ntawm cov neeg lub koom pheej sib cais ntawm xov tooj cua zaus kom tau raws li cov kev xav tau ntawm cov kev xav tau sib txawv ntawm cov lag luam sib txawv.

Txawm li cas los xij, cov ntaub ntawv faib tshwj xeeb ntawm 1250mHz zaus band tsis paub meej hauv cov ntaub ntawv pej xeem.

Thoob Ntiaj Teb Spectrum Them Nqi Zog:

Lub Peb Hlis 2024, Asmeskas Cov Neeg Saib Xyuas Cov Neeg Saib Xyuas Kev Pom Zoo ntawm 2024, thov kom muaj kev sib tw ntawm 1.

Yav Tom Ntej Outlook:

Nrog rau kev txhim kho kev sib txuas lus nrawm nrawm ntawm cov wireless kev sib txuas lus siv thev naus laus zis, qhov kev thov rau cov peev txheej spectrum yog loj hlob. Tsoomfwv thiab cov chaw lis haujlwm muaj feem xyuam tau kho cov tswv yim Spectrum cov tswv yim kom tau raws li qhov kev xav tau ntawm kev siv tshuab tawm ntawm cov thev naus laus zis. Raws li ib nrab-band spectrum, 1250mHz band tau zoo tshaj tawm cov yam ntxwv thiab yuav siv hauv ntau daim teb hauv lub neej yav tom ntej.

Hauv cov ntsiab lus, lub 1250MHz Band yog tam sim no tsuas yog siv hauv satellite kev sib txuas lus thiab kev sib txuas lus. Nrog rau kev txhim kho thev naus laus zis thiab kev hloov kho ntawm cov cai tswj hwm kev tswj hwm kev tswj hwm, daim ntawv thov tau txais kev tswj hwm ntawm no band yuav tsum tau txuas ntxiv mus ntxiv.
