Mafoni a Satellite

Mafunso Ofunsidwa Kawirikawiri

Kubwereketsa mafoni a satellite
Kubwereketsa foni ya satana pamwezi ndi mtengo wapakati wa PLN 1000 - PLN 1300 kapena PLN 50 patsiku.

Kubwereka foni ya satellite kungakhale njira yabwino komanso yotsika mtengo kwa anthu kapena mabungwe omwe amafunikira mwayi wolumikizana kwakanthawi kapena kwakanthawi kogwiritsa ntchito ma satellite, makamaka m'malo opanda intaneti. Mwachitsanzo, apaulendo opita kumadera akumidzi kapena akumidzi, anthu omwe akuchita nawo ntchito zakunja, kapena mabungwe omwe ali ndi anthu ogwira ntchito m'munda akhoza kupindula ndi kubwereketsa mafoni a satellite.

Kulembetsa kwa foni ya satellite
Timakhazikitsa mapangano olembetsa kwa makasitomala aku Poland ndi Europe.

Mtengo wolembetsa wa Iridium ndi wofanana ndi USD 70 pamwezi. Mtengo wapakati wamayimba pamphindi ndi USD 1.40, SMS USD 0.50.

Kutsegula mu netiweki ya Thuraya kumawononga USD 26, kulembetsa pamwezi USD 16-35, kuyimba miniti USD 0.68 - USD 0.79 kapena USD 1.12-2.37, SMS USD 0.41.

Inmarsat imawononga USD 65 pamwezi, USD 1.00-1.20 pamphindi, USD 0.50 pa SMS.

Kodi foni ya satellite imagwira ntchito bwanji?
Foni ya setilaiti imagwira ntchito polumikizana ndi ma satelayiti omwe amazungulira Padziko Lapansi kuti apereke ntchito zoyankhulirana zamawu ndi data m'malo opanda netiweki yapadziko lapansi. Foni ili ndi cholumikizira chomwe chimatumiza ndikulandila ma siginecha kupita ndi kuchokera kumasetilaiti. Transceiver imatembenuza ma siginecha omvera kuchokera pa foni kukhala ma siginecha a wailesi, omwe kenako amatumizidwa ku ma satellite. Kenako masetilaitiwo amatumiza ma siginali ku siteshoni yapansi, yomwe imatumiza ma siginoloji ku foni ya wolandirayo kapena ku netiweki ya telefoni ya public switched (PSTN) kuti ipitirire ku foni yapansi kapena lamya ya m’manja. Njirayi imasinthidwa pama foni obwera.

Kuti foni ya satellite igwire ntchito, iyenera kukhala ndi mzere wowonekera bwino wakumwamba, popeza chizindikirocho chiyenera kuyenda kuchokera pa foni kupita ku ma satellites ndi kubwerera. Mawonekedwe azizindikiro angakhudzidwe ndi nyengo, ndipo latency (nthawi yomwe siginecha imayenda kuchokera pa foni kupita ku satelayiti ndi kubwerera) nthawi zambiri imakhala yokwera kuposa maukonde amtundu wapadziko lapansi. Komabe, mafoni a satana amapereka njira yodalirika komanso yabwino yolankhulirana kwa anthu ndi mabungwe omwe ali kutali kapena kumidzi, panyanja, kapena mlengalenga, kumene njira zina zoyankhulirana sizikupezeka.

Smartphone ya satellite
Opanga ma foni a m'manja angapo akugwira kale ntchito pazinthu za satellite pama foni am'manja. Ku China, Huawei Mate 50 imakupatsani mwayi wotumiza ma SMS a satellite mothandizidwa ndi netiweki ya BeiDou navigation. Apple iPhone ili ndi njira iyi ku US, Canada, Germany, Ireland ndi UK. Qualcomm ikugwira ntchito kale pa Snapdragon Satellite chip yomwe imathandizira mawonekedwe ofanana ndi mafoni a Android. SpaceX yalengezanso kukhazikitsidwa kwa ntchito zoyankhulirana za satellite zam'manja za 5G monga gawo la network ya Starlink.

Kodi mungayang'anire foni ya satellite?
Inde, ndizotheka kutsata foni ya satellite. Mafoni ena a satelayiti ali ndi luso la GPS lokhazikika, lomwe limawalola kuti azitsatiridwa munthawi yeniyeni. Izi nthawi zambiri zimagwiritsidwa ntchito pazachitetezo komanso chitetezo, makamaka kumadera akutali kapena kowopsa. Kuphatikiza apo, ena opereka mafoni a satellite amapereka ntchito zolondolera zomwe zimalola wogwiritsa ntchito kuyang'anira komwe foni ili.

Izi zitha kukhala zothandiza poyang'anira anthu ogwira ntchito m'munda kapena poyankha zadzidzidzi. Komabe, ndikofunikira kudziwa kuti kutsatira foni ya satellite kumafuna kupeza deta ya GPS ya foni yam'manja ndipo kumadalira kupezeka kwa ma siginecha a satellite ndi zolephera zina zaukadaulo. Kutha kuyang'anira foni ya satellite kumathanso kutsatiridwa ndi malamulo am'deralo, komanso malingaliro achinsinsi.

Kodi zokambirana za patelefoni za satellite zitha kujambulidwa?
Kukambitsirana pa foni ya satellite kumatha kulumikizidwa ngati njira ina iliyonse yolumikizirana. Komabe, chitetezo cha mauthenga a pa satellite pa telefoni chingadalire pazinthu zosiyanasiyana, kuphatikizapo njira zolembera ndi zovomerezeka zomwe zimagwiritsidwa ntchito ndi opereka mafoni a satana, ubwino wa mapulogalamu obisala, ndi chitetezo cha intaneti ya foni ya satellite.

Kawirikawiri, opereka mafoni a satana amagwiritsa ntchito njira zolembera ndi zovomerezeka kuti ateteze kulankhulana pakati pa foni ya satellite ndi satellite network, komanso pakati pa satellite network ndi siteshoni yapansi. Komabe, chitetezo cha njirazi chikhoza kusokonezedwa ngati pulogalamu ya encryption idabedwa kapena ngati maukonde sali otetezedwa bwino.

Ndikofunikira kudziwa kuti kulandidwa kwa zokambirana pa foni yam'manja kumayenderana ndi malamulo am'deralo, komanso malingaliro achinsinsi. Nthawi zina, maboma ndi mabungwe azamalamulo atha kuletsa mwalamulo kulumikizana ndi mafoni a satelayiti pofuna chitetezo cha dziko kapena kufufuza milandu.
Pofuna kuonetsetsa chitetezo ndi chinsinsi cha mauthenga a pa telefoni pa satellite, tikulimbikitsidwa kugwiritsa ntchito opereka mafoni a satana odalirika komanso odalirika, komanso kudziwa kuopsa kwa chitetezo chokhudzana ndi mauthenga a pa satellite.

Foni ya satellite yankhondo
Mafoni a satelayiti ankhondo ndi mafoni apadera a satellite omwe amapangidwa kuti azigwiritsidwa ntchito ndi asitikali omenyera nkhondo. Mafoniwa amapereka mautumiki otetezedwa ndi odalirika olankhulirana mawu ndi data kwa asitikali omwe ali kutali kapena kowopsa komwe maukonde akudziko lapansi sakupezeka. Mafoni a satellite ankhondo amapangidwa kuti athe kulimbana ndi zovuta zachilengedwe ndipo adapangidwa kuti azikhala olimba komanso olimba.

Kuphatikiza pa mawonekedwe amafoni a satellite, mafoni a satana amathanso kukhala ndi zida zapamwamba zachitetezo monga kubisa komanso njira zotsimikizira kuti ziteteze zambiri. Atha kupangidwanso kuti akwaniritse miyezo ndi zofunikira zankhondo, monga MIL-STD-810, yomwe imatanthauzira miyezo ya kulimba, kulimba, komanso kukana chilengedwe.

Mafoni a satelayiti ankhondo nthawi zambiri amagwiritsidwa ntchito ndi asitikali, kuphatikiza asitikali, amalinyero, airmen, ndi apanyanja, kuti alankhule ndi likulu lawo ndi magulu ena omwe ali m'munda. Amapereka ulalo wofunikira wa ntchito zankhondo ndi chithandizo, makamaka m'malo akutali kapena owopsa, pomwe njira zina zolumikizirana sizipezeka kapena zodalirika.

Timapereka mafoni a satellite ovomerezeka ankhondo ndi oyang'anira boma. Izi ndi mitundu ya Iridium 9555 GSA ndi Iridium 9575 GSA.
