GLB3300MG GPS fibre optic extender
Incazelo Yomkhiqizo
Isixhumanisi sefayibha ye-GLB3300MG singaletha i-GNSS (GPS, GLONASS, Galileo, Beidou) isignali ye-RHCP RF yesathelayithi yokuzulazula isuka othini yangaphandle iye kunoma yiliphi ihhovisi elingaphakathi ngaphakathi.10Ibanga le-fiber Km.
I-GNSS i-Global Navigation Satellite System, ikakhulukazi ihlanganisa i-GPS (US), GLONASS (Russia), GALILEO (European Union) kanye ne-BDS (China). Ngokusekelwe kumasathelayithi amaningi azungeza umhlaba, i-GNSS inikeza abasebenzisi izinsiza zokubeka, ukuzulazula, kanye nesikhathi (PNT) emhlabeni jikelele noma wesifunda. Le sistimu iqukethe amasegimenti amathathu: ingxenye yesikhala, ingxenye yokulawula, kanye nesegimenti yomsebenzisi. .
Njenge-inthanethi, i-GNSS iyingxenye ebalulekile yengqalasizinda yolwazi lomhlaba wonke. Imvelo yamahhala, evulekile, nethembekile ye-GNSS iholele ekuthuthukisweni kwamakhulu ezinhlelo zokusebenza ezithinta yonke ingxenye yempilo yesimanje. Ubuchwepheshe be-GNSS manje sebukukho konke kusukela kumaselula namawashi asesihlakaleni kuya ezimotweni, ogandaganda, iziqukathi zokuthutha, nama-ATM.
Zonke izimpondo zesathelayithi zidinga indawo evulekile ukuze zithole amasiginali e-RF esibhakabhakeni. Isignali ye-GNSS RF inokubambezeleka okuphezulu phezu kwentambo ye-coaxial. Isixhumanisi sefayibha ye-GLB3300MG sinweba isevisi ye-GNSS kanye namasiginali wokulingisa we-GNSS kusukela ngaphandle kuya endlini nangaphansi. Isevisi ye-GNSS ingatholakala emahhovisi angaphakathi, ezimakethe ezingaphansi komhlaba, emhubheni, kuma-metro, ezindaweni zokupaka zezakhiwo eziphakeme.
Izinga le-GNSS RF cishe li- -120dBm, lingaphansi kakhulu kunokusakaza okuvamile kwe-Satellite TV. I-GLB3300MG yakhelwe ngaphakathi izikhulisamsindo eziphansi ze-GaAs, i-laser yomugqa ophezulu kanye ne-photodiode ukuze kuqinisekiswe ikhwalithi yesignali ye-GNSS ehamba phambili ngemva kokudluliswa kwefayibha. I-GLB3300MG isebenza kahle ku-GPS phezu kwefayibha, i-BDS ngaphezu kwezinhlelo zokusebenza zefayibha. I-GLB3300MG ingasebenza nesifanisi se-GNSS ukuze inikeze iphuzu elilodwa kumasiginali wokuzulazula wamaphuzu amaningi phezu kwezintambo ze-fiber optic.
Ezinye izici:
•I-Aluminium Die Cast Housing noma 19” 1RU izindlu zangaphakathi.
•Isekela i-GPS GLONASS Galileo Beidou Satellite RF isignali phezu kwefayibha.
•Inikeza amandla angu-5.0V DC we-antenna yangaphandle ye-GNSS.
•I-laser ephezulu yomugqa ne-Photodiode.
•I-GaAs Low Noise Amplifier.
