Nā nīnau hoʻohālike ukali geostationary

2 Nā laʻana o nā nīnau ukali geostationary

1. ʻO nā satelite geostationary a i ʻole nā ​​satelite geosynchronous he mau satelite ia e kū ana ma hoʻokahi a me ke kiko like ma luna o ka equator o ka Honua. Hoʻohana ʻia kēia mau satelite e hoʻouna i nā hōʻailona kamaʻilio (TV, kelepona paʻalima), nā wānana o ke aniau, a pēlā aku. Pehea ke kiʻekiʻe o nā satelite geostationary ma luna o ka ʻili o ka Honua?
G = ke kūpaʻa umekaumaha honua = 6,67 x 10^-11 N m²/ kg²
M = ka nuipa o ka honua = 5,97 x 10²⁴ kg
T = ka manawa o ka hoʻohuli ʻana o ka ukali = ka manawa o ka hoʻohuli ʻana o ka Honua = 24 hola = 24 (3600 kekona) = 86.400 kekona = 8,64 x 10⁴ ka lua

Ua helu ʻia ke kiʻekiʻe o ka satelite me ka hoʻohana ʻana i kēia ʻano hana:
Ma hea ʻo r = ka mamao o ka satelite mai ke kikowaena o ka honua
Hiki ke aʻo ʻia ka loaʻa ʻana o kēia ʻano hana ma ka ʻatikala e pili ana Satellite Geostationary.
Ka mamao o ka ukali mai ke kikowaena o ka honua = 4,22 x 10⁷ mika = 4,22 x 10⁴ km = 42.200 km
Ka radius o ka Honua = 6,38 x 10⁶ mika = 6,38 x 10³ km = 6.380 km

Ka mamao o ka ukali mai ka ʻili o ka honua = ka mamao o ka ukali mai ke kikowaena o ka honua - ka radius o ka honua
Ka mamao o ka ukali mai ka ʻili o ka honua = 42.200 km – 6.380 km
Ka mamao o ka ukali mai ka ʻili o ka honua = 35.820 km

No laila, ʻo ke kiʻekiʻe o ka satelite ma luna o ka equator he 35.820 kilomita.

2. I mea e noho mau ai kahi satelite geostationary ma kahi like ma luna o ka equator, pono e like ka wikiwiki orbital o ka satelite geostationary me ka wikiwiki orbital o ka Honua. He aha ka wikiwiki orbital o kahi satelite geostationary?
G = ke kūpaʻa umekaumaha honua = 6,67 x 10^-11 N m²/ kg²
M = ka nuipa o ka honua = 5,97 x 10²⁴ kg
r = ka mamao o ka ukali mai ke kikowaena o ka honua = 4,22 x 10⁷ mika

Hiki ke helu ʻia ka wikiwiki o kahi ukali geostationary me ka hoʻohana ʻana i kekahi o nā ʻano hana ʻelua aʻe.
Hiki ke aʻo ʻia ka loaʻa ʻana o kēia ʻano hana ma ka ʻatikala e pili ana Satellite Geostationary.

ʻO ka wikiwiki o ke kaʻapuni o ka satelite he 3.070 mika/kekona.

Hiki ke helu ʻia ka wikiwiki orbital o kahi ukali geostationary me ka hoʻohana ʻana i ka hoohalike ma lalo nei.
ʻO ka wikiwiki o ke kaʻapuni o ka satelite he 3.070 mika/kekona.
