● Phau ntawv los yog lub cev muaj zog 2.4m C-band earth station antennas
● Phau ntawv los yog lub cev muaj zog 2.4m Ku-band earth station antennas
Peb lub tuam txhab muab ntau yam khoom sib txuas lus satellite. Tsis tas li ntawd, peb muab tag nrho cov kev pabcuam suav nrog kev tsim qauv engineering, kev teeb tsa, kev hloov kho, kev saib xyuas thiab kev cob qhia nrog kom zoo dua ntawm nws cov khoom siv technology tom qab, kev paub ntau yam engineering thiab cov cuab yeej siv siab heev.
Lub kav hlau txais xov yog ib qho yooj yim rau nruab, lub reflector tuaj yeem hloov pauv tau yooj yim thiab nws muaj qhov ua tau zoo dua - kev teeb tsa.
Peb tsim rau txhua yam ntawm peb lub ntiaj teb chaw nres tsheb kav hlau txais xov zoo-kho chaw thiab Az-EL locking device.
Peb muab cov neeg siv nrog cov ntawv qhia tshwj xeeb rau lub ntiaj teb chaw nres tsheb kav hlau txais xov teeb tsa, daim ntawv thov thiab kev saib xyuas nrog rau kev cob qhia kev siv tshuab los pab cov neeg siv nruab, kho, siv thiab tswj lub kaw lus.
Txij li thaum lub installation precision ntawm sub reflector muaj ib tug muaj zog nyhuv ntawm cov hluav taws xob kev ua tau zoo ntawm av kav hlau txais xov, peb tau tsim sub reflector thiab yuav muab lawv rau cov neeg siv, lub installation ntawm sub reflector yog yooj yim rau tswv, thiab yog li kom tsis txhob lub kav hlau txais xov kev ua tau zoo txo.
Peb yuav tsim tsim thiab muab cov khoom hloov pauv tsim nyog raws li ODU tsim los ntawm cov chaw tsim khoom uas tau xaiv los ntawm cov neeg siv khoom.

Qhov zoo:
● Cov2.4m kav hlau txais xov siv lub optimized tsim thiab advanced siv technology. Nws muaj qhov nce siab, qis sab lobe, me VSWR thiab lwm yam. Peb lub kav hlau txais xov tuaj yeem ua tau raws li CCIR580 thiab INTERSAT.
● Tag nrho cov hlau ntawm lub kav hlau txais xov yog tsim los ntawm kub-dip zinc uas tuaj yeem tiv thaiv zinc los ntawm volatilization. Tag nrho cov khoom siv tawv tau txais cov hlau tsis muaj steel los xyuas kom meej lub kav hlau txais xov 15 xyoo yam tsawg kawg nkaus lub neej expectancy txawm tias nws nyob rau hauv qhov chaw phem.
● 2.4m av kav hlau txais xov muaj linear polarization thiab ncig polarization pub, thiab koj tuaj yeem xaiv 2 qhov chaw nres nkoj, 3 chaw nres nkoj lossis 4 qhov chaw nres nkoj. Cov linear polarization tuaj yeem hloov mus rau lub voj voog polarization txiav nrog kev xaiv.
● Peb lub kav hlau txais xov 2.4m muaj qhov sib xws ntawm C, Ku, X thiab L bands, thaum tus neeg siv kawg xav siv band tshiab, lawv tsis tas yuav yuav lub kav hlau txais xov tshiab. Los ntawm kev hloov cov kab ke band, lawv tuaj yeem paub cov kev xav tau tshiab.
● Raws li qhov yuav tsum tau muaj ntawm cov neeg siv kawg, peb tuaj yeem nruab cov khoom siv deicing thiab snowmelt ntawm lub ntsiab reflector nrog kev tswj tsis siv neeg thiab muab cov nag thiab daus tshuab rau khoom noj. peb kuj tuaj yeem muab kev tiv thaiv xob laim thiab cov khoom siv hauv av, lub teeb tswj lub teeb ceeb toom aviation.
● Raws li qhov yuav tsum tau muaj ntawm cov neeg siv kawg, tsav hom 2.4m kav hlau txais xov tuaj yeem ua tau raws li 0-360℃azimuth thiab 0-90℃nce.
Daim ntawv thov:
● Nws yog dav siv los ntawm kev sib txuas lus.
● Nws tuaj yeem siv los ntawm Seismological Bureau, txoj kev thiab kev tsav tsheb, tsoomfwv, thiab lwm yam.
● Nws yog dav siv los ntawm Lub Xeev Weather Bureau.
