Kev sib tham ntawm lub xov tooj cua satellite xov tooj cua

Satellite xov tooj xov tooj radios, ua cov khoom siv hluav taws xob muaj xwm txheej ceev rau kev tsim kho cov txheej txheem thiab kev teeb tsa kom ntseeg tau tias cov chaw ua haujlwm nyuaj. Kab lus no piav qhia cov kev tsim kho cov kev tsim kho los ntawm peb kev xav: kev teeb tsa ib puag ncig, khoom ua haujlwm, thiab kev nyab xeeb.

I. Kev teeb tsa ib puag ncig cov qauv

Kev xaiv tus xaib yuav tsum tau ua kom tau txais kev pab cuam sab nrauv thiab kev tiv thaiv lub cev. The satellite phone antenna should be installed in an open area, away from obstructions such as high-rise buildings and mountains that may affect satellite signal reception. Qhov nce kaum sab xis ntawm tsawg kawg 10℃thiab thaj chaw ntshiab dawb ntawm cov electromagnetic cuam tshuam. Yog hais tias lub xov tooj cua moduule nyob rau ntawm cov cim shortwave, nws yuav tsum nyob deb ntawm high- kev cuam tshuam thiab tshuab hloov pauv. Cov khoom siv uas siv tau yuav tsum muaj IP65 kev ntaus nqi lossis siab dua, kev ua haujlwm tsawg dua 60 xyoo) kom tiv thaiv kev puas tsuaj rau lub voj voog thaum lub sij hawm nag xob nag cua thaum nag xob nag cua.

Ii. Cov Khoom Siv Khoom Ua Haujlwm

Tshaj tawm -} Kev Txhim Kho Kev Tiv Thaiv yog qhov yuav tsum tau ua hauv ntau qhov ntev. Lub xov tooj satellite yuav tsum xeem dhau lub teeb liab ntau dua lossis sib npaug ntawm - 120dbm) kom muaj kev sib txuas ruaj khov rau lub satellite txuas. Lub xov tooj cua ntaus ntawv yuav tsum yog ntsuas rau cov zaus ntau zaus (piv txwv li, AM 520}} 1710.5-108mhz), thiab lub suab nrov nrov tshaj tawm yuav tsum tshaj 40db. Tag nrho cov kab sib txuas yuav tsum tau siv oxidation-resistant kub-plated txuas, thiab cable bend radius yuav tsum muaj tsawg kawg 10 zaug nws lub taub kom tiv thaiv teeb liab attenuation. Thaum lub sij hawm ua haujlwm ntsuas theem, cov xwm txheej xws li hluav taws xob thiab lub roj teeb hluav taws xob yuav tsum tau hloov kho lub sijhawm hloov mus ntxiv lossis sib npaug rau 48 teev).

III. Kev Nyab Xeeb thiab Txij Nkawm

Kev tsim kho yuav tsum ua raws cov kev nyab xeeb hluav taws xob thoob plaws tag nrho cov txheej txheem, thiab siab {{voltage ua haujlwm yuav tsum tau ua nrog daim ntawv tso cai. Kev tshawb xyuas ib txwm (peb hlis) yuav tsum tau tom qab kev tshaj tawm, tsom rau cov teeb meem xws li tshuaj tiv thaiv kev xeb thiab kev laus. Tus neeg siv phau ntawv yuav tsum tau qhia meej meej rau cov cheeb tsam kev tsim kho polar, cov cheeb tsam ntawm cov cheeb tsam kom ntseeg tau tias niaj hnub ua haujlwm.

Nruj dua rau cov qauv no tuaj yeem txhim kho cov kev sib txuas lus ua tau zoo ntawm lub xov tooj satellite thiab cov haujlwm ua haujlwm.
