Te Aituā: Mai i ngā Ngaronga Tūpono ki te Ua Nui
Kāore i puta ohorere te wehenga nui o ngā amiorangi LEO a Starlink. Mai i te whakarewatanga tuatahi o te kaupapa i te tau 2019, he iti noa iho ngā mate o ngā amiorangi i te tīmatanga (2 i te tau 2020), he rite ki ngā reiti hekenga e tumanakohia ana. Heoi, i te tau 2021 ka piki ake te maha (78 ngā mate), ā, i muri mai ka piki haere tonu ngā taumata teitei (99 i te tau 2022, 88 i te tau 2023). I eke te raruraru ki tōna taumata teitei i te tau 2024 me te 316 ngā amiorangi i tahuna—e toru ngā tatauranga o ngā tau kua hipa—e 583 ngā mate katoa, he rite ki te ~1 amiorangi i ngaro i ia rā, ki te 1 rānei i roto i te 15 kāore i oti tana misioni.
Te Mahi a te Rā: Te Kaihara e Kitea ana
E whakaū ana ngā rangahau a NASA i te hononga tika i waenga i te hekenga o te amiorangi me ngā huringa o te rā. I tūtaki te whakarewatanga o te tau 2019 ki te iti rawa o te rā, engari i te kaha haere o te mahi a te rā, ka piki ake te tōia o te āhuarangi i ngā porowhita 340-550km mā te >50% i ngā wā o ngā awha geomagnetic. Ka puta tēnei ina:
- Ko ngā mura o te rā/ngā pananga papatipu korona e pupuhi ana i te Ao
- Ka wera, ka whakawhanui hoki ngā awha geomagnetic i te āhuarangi o runga
- Ka whakanuia e te hau whānui te tōia, ka pirau ai te porowhita
Paradox: He nui ake te whakamate o ngā tupuhi ngoikore
He rerekē ki ngā tumanakohanga, 70% o ngā ngaronga i puta i ngā awha aukume āhua-waenga/ngoikore. Mā ēnei huihuinga roa (ngā rā/wiki) ka heke haere te kaha o ngā porowhita, ā, ka kore e taea te whakaora, he rerekē ki ngā awha kaha engari poto. He tauira nui: 40 o ngā amiorangi Starlink 49 i whakarewaina i te Hui-tanguru 2022 i mate i ngā awha ngoikore tonu.
Ngā Tauwhitinga Āmiomio-Iti
Ahakoa e taea ana e ngā porowhita 550km o Starlink te whakawhitiwhiti kōrero iti-roa, ko tō rātou tata ki a Papatūānuku:
- Ka whakawhāiti i te roanga mahi ki te ~5 tau (ki te 400km te tawhiti o te ISS)
- Ka whakanui ake i ngā pānga tōia i te wā e kaha ana te rā
- Ka tino whakararu i ngā amiorangi whakamātautau i te teitei 210km
Ngā Wero o te Ao
Me te neke atu i te 6,000 ngā amiorangi Starlink e porowhita ana i te wā o te mōrahi o te rā—he huihuinga tawhito—e whakatūpato ana ngā kaipūtaiao mō:
- Te tere o te hekenga o te amiorangi
- Mā te tere o te whakakī me ngā kawa aunoa mō te hurihanga o te ozone ka whakaitihia te nui o ngā tukunga o te konumohe i te hokinga mai o SpaceX, engari he mea nui tonu te manawanui o te huringa o te rā puta noa i te umanga.
Whakamutunga
E whakaatu ana tēnei kaupapa i te mana o te taiao ki runga ake i te hangarau tangata, ā, e whakaatu ana hoki i te hiahia mō ngā hoahoa pūnaha LEO e whai whakaaro ana ki ngā awe o te rā huri noa.
He kaihanga ngaio a Chengdu Concept Microwave Technology CO.,Ltd o ngā wāhanga RF 5G/6G mō te whakawhitiwhiti kōrero amiorangi i Haina, tae atu ki te tātari RF iti-haere, te tātari teitei-haere, te tātari bandpass, te tātari notch/tātari aukati band, te duplexer, te wehewehe hiko me te hononga ahunga. Ka taea te whakarite i ēnei katoa kia rite ki ō hiahia.
