I. Ka da fɛnsɔrɔsiraw kɔrɔlenw kan waati min ka bon-Tiɲɛni na
Sitimɛ kɔrɔ suguya caman na, waati ɲɔgɔndan tigitigi tɛ fɛɛrɛko dɔrɔn ye, nka a ye lakana ni sabatili garanti ye. I n'a fo:
Power Grid Systems: A bɛ waati ɲɔgɔndan nanosekɔndi-nivo de wajibiya walasa ka fili yɔrɔ sɔrɔ, fasa sumani, ani sabatili kɔlɔsili lakanani. Waati jiginni bɛ se ka kɛ sababu ye ka lakanani baarakɛbaliya walima rezow basigibaliya.
Kumaɲɔgɔnya rezow : Kɛrɛnkɛrɛnnenya la, yɔrɔ minnu ka dɔgɔ-latɛmɛnenw na i n’a fɔ 5G ani fɛnw ka Ɛntɛrinɛti (IoT), waati ɲɔgɔndan basigiyɔrɔw ni ɲɔgɔn cɛ, o bɛ nɔ bila kumaɲɔgɔnya jogo la ani spektrum nafama na.
Nafolo jago siraw: Jagokɛlaw ka caya-frequency, blockchain settlement, ani baara wɛrɛw bɛ u jigi da microsecond-level timestamps kan walasa ka jagokɛcogo sigicogo n’a fɛn caman sɛmɛntiya.

O baarakɛminɛnw bɛ fɛn caman ɲini waati taamasiyɛnw taabolo, u tiɲɛni ani u dannayako la. Hali n’a y’a sɔrɔ sateliti taamasiyɛnw bɛ se ka diɲɛ kɔnɔ, waati tigitigi-fɛrɛnkanko ɲɛfɔliw di, u ka se ka sigida nɔfɛkow kɛ, o bɛ dɔ fara u kan ani ka u lakana sigida ka waatilan minɛnw fɛ minnu sabatilen don kosɛbɛ.
II. Fɛɛrɛko wajibiyalen jɔnjɔnw Sateliti-OCXO kalibrelenw na
Walasa ka sateliti taamasiyɛnw tigɛcogo walima fɛn tiɲɛnenw ɲɛnabɔ minnu bɛ se ka kɛ, sateliti-kalibre OCXOw ka kan ka nin fɛɛrɛ gɛlɛn ninnu dafa:
Waati yɛrɛmahɔrɔnyalen ɲuman-Seko ni dɔnko marali:
Ni kɛnɛma jateminɛ taamasiɲɛw tununna, OCXO ka kan ka frequency bɔli mara a ka high-stability oscillator fɛ. A ka waati kunkurunnin ni waati jan-fɛrɛnkan sabatili ka kan ka bonya kosɛbɛ walasa ka a to sistɛmu waati filiw ka to dan na min bɛ sɔn taamasiyɛnw tiɲɛni waati.
Teliya sɔrɔli ani segin-ka-bɔnye seko:
Ni sateliti taamasiyɛnw seginna, OCXO ka kan ka teliya ka segin ka -dabɔ ani ka jateminɛ kɛ, ka finɛtiri dɔgɔya, sistɛmu bɛ baara kɛ min kɔnɔ k’a sɔrɔ waati tigitigi ma kɛ. Yɛlɛma teliya algorisimuw ani mankan dɔgɔman-fasa-mankanw dilanni ye fɛnba ye walasa ka o seko in sɔrɔ.
Laminiko ladamuni ni dannaya barikama:
Tuma caman na, yɔrɔ minnu nafa ka bon, olu bɛ bila sigida suguya caman na, i n’a fɔ kɛnɛma, minɛnw so ani dugujukɔrɔyɔrɔw. OCXOw ka kan ka baara sabatili sabati funteni ni nɛnɛ jiginni, yɛrɛyɛrɛ, ani kuran sɔgɔli cogoyaw la, minnu bɛ kɛ ni sɔgɔsɔgɔninjɛ barikama ye, funteni bɔli, ani lakanani dilancogo.
Dɛmɛ min bɛ kɛ ka ɲɛsin caman-Sistɛmu bɛnkan ma ani Anti-Interference seko ma:
Bi waati jatebɔ moduluw ka teli ka sateliti sigida caman dɛmɛ, i n’a fɔ GPS, BeiDou ani GLONASS, ani ka filɛri ni taamasiyɛnw bonya fɛɛrɛw don u kɔnɔ walasa ka baarakɛcogo ɲɛ kuran sigida gɛlɛnw na.
III. Aplikasi kɛcogo minnu bɛ kɛ cogoya la
Waati ɲɔgɔndan minɛnw ka ɲɛsin Smart Grids ma:
Gara fitininw ni ciyɔrɔw la, waati jateminɛminɛn minnu bɛ ni OCXO ye, olu bɛ kɛ master walima extension clocks ye. Ni u bɛ cogoya la, u bɛ jateminɛ kɛ sateliti taamasiyɛnw fɛ. Ni sateliti dakun tununna, OCXO bɛ se ka waati tiɲɛni sabati, ka baara kɛtaw sabati i n’a fɔ layini danfara lakanani ani ko kɛlenw sɛbɛnni.
Waati-Frequency Supply Units ka ɲɛsin kumaɲɔgɔnya basigilenw ma:
Kɛrɛnkɛrɛnnenya la, yɔrɔjanw na walima so kɔnɔ, sateliti taamasiyɛnw barika ka dɔgɔ yɔrɔ minnu na walima minnu tɛ sɔrɔ, OCXOw bɛ se ka sigida wagati sɔrɔyɔrɔ sabatilenw di basigiyɔrɔw ma, ka fɛnw tabaga ka ɲɔgɔndɛmɛ ni karamɔgɔ waatiw sabati, ani ka ɛntɛrinɛti kumaɲɔgɔnya sabati min tɛ tigɛ.
Waati Serverw ka ɲɛsin Nafolo kunnafonidilanw ma:
Nafolosɔrɔsiraw ka sariya ni jatebɔ ɲininiw ɲinini gɛlɛnw bɛ waati kɔnɔ. Waati baarakɛla minnu bɛ baara kɛ ni sateliti-OCXO jateminɛlenw ye, olu bɛ se ka waati jateminɛ kelen ni dannayalen mara hali ni kunnafonidilanw tɛ se ka sateliti taamasiyɛnw sɔrɔ, ka baara nafamaw dɛmɛ i n’a fɔ gafemarayɔrɔw tilatilali ani jagokɛlaw ka ɲɛnabɔli.
Telewisɔn min bɛ bɔ kɛnɛ kan, o ye ɲɔgɔndɛmɛ siraw ye:
Telewisɔn cikanw ni u jɛnsɛnni rezow kɔnɔ, yɔrɔ caman bɛ ɲɔgɔndɛmɛ gɛlɛn de wajibiya walasa taamasiyɛnw kana ɲɔgɔn dafa walima ka u tigɛ. OCXOw bɛ se ka taa a fɛ ka wagatiw di minnu bɛ bɛn ɲɔgɔn ma ni sateliti taamasiyɛnw bɛ nɔ bila waati walima dugukoloko fɛnw na, o bɛ kɛ sababu ye ka kunnafonidi lakanani sabati.
IV. Kuncɛli
Jamana ka fɛnsɔrɔsiraw nizɛriyali ni ɲɔgɔndɛmɛ bɛ ka taa ɲɛ cogo min na, waati ɲɔgɔndanba -tiɲɛni kɛra "ɲɛnamaya sira dogolen" nafamaba ye min bɛ sigida baarakɛcogo dafalen dɛmɛ. Sateliti-kalibre OCXOw bɛ sateliti taamasiyɛnw diɲɛ kɔnɔ tiɲɛni fara ɲɔgɔn kan ni sigida jiginniw sabatili waati kunkurunnin-la ye, ka waati dɔgɔyali barika gɛlɛn dɔ da taamasiyɛnw anomaliya waatiw la. Don nataw la, ni taamasiyɛnw yɛrɛmahɔrɔnyalenw kɔgɔli ye i n’a fɔ BeiDou ani ko kɛlen kuraw bonya i n’a fɔ IoT ani Ɛntɛrinɛti izini, nin fɛɛrɛ in bɛna jɔyɔrɔba ta ko nafamabaw la, ka jusigilan jɔnjɔn sigi fɛnsɔrɔsiraw kura waati jateminɛw kama.
