Ituaiga 50 Fiber Strapdown Inertial Navigation System
Fa'amatalaga o oloa
Ituaiga 50 Optical Fiber Integrated Navigation System, o se fofo sili ona lelei ua fa'ainisinia ma'oti e maua ai le fa'atinoga le mafaatusalia.O lenei faiga e aofia ai se gyroscope faʻapipiʻi faʻapipiʻi faʻapipiʻi ma mama e tolu-axis faʻapipiʻi tapuni, faʻavavevave, ma le kata taʻiala, e ofoina atu le taugata faʻapitoa.O le fa'aogaina o le tele-sensor fusion ma fa'atautaia algorithms, e tu'uina atu ai fua sa'o o uiga, ulutala, ma fa'amatalaga tulaga ma le sa'o lelei.
Fuafuaina ma le femalamalamaa'i i le mafaufau, o le ituaiga 50 faiga e maua ai lona fa'aoga atoatoa i faiga fa'atatau i fe'avea'i ma maualuga ma va'ava'ava'a i ta'avale ele'a (UAV).O lona tu'ufa'atasiga lelei ma le fa'atuatuaina o le fa'atinoga e avea ai ma aseta taua mo pisinisi eseese, e aofia ai su'esu'ega, fa'afanua, ata fa'a'ea, ma isi mea.
Tofo i le tumutumu o tekinolosi tau folauga ma le Type 50 Optical Fiber Integrated Navigation System, e mafai ai ona e tatalaina tulaga fou o le saʻo ma le lelei i au gaioiga.
GALUEGA AUTU
O le faiga e ofoina atu le tu'ufa'atasiga inertial/satelite navigation mode ma le mama inertial mode.
I le inertial/satellite navigation mode, o le GNSS receiver i totonu e faʻaogaina faʻamatalaga faʻatulagaina satelite mo faʻasalalauga tuʻufaʻatasia ma faʻaalia le pitch, taʻavale, ulutala, tulaga, saoasaoa, ma faʻamatalaga taimi.A leiloa le faailo, o le gaioiga e aofia ai le tulaga, saosaoa, ma uiga e fuafuaina e le inertia, faatasi ai ma se manaʻoga e faʻatumauina saʻo le pitch ma le taʻavale, faʻatasi ai ma se galuega puʻupuʻu o loʻo umia ma le saʻo o le tulaga mita.
O le mama inertial mode (leai se fusiga GPS e tupu pe a uma le paoa, ma afai e toe leiloa loka pe a maeʻa le fusi, e ulufale atu i le faʻaogaina faʻaogaina mode) faʻaalia se galuega saʻo fua o uiga, ma e mafai ona maua le pitch, taʻavale, ulutala, ma faia suʻesuʻega i matu. fa'avae i luga ole inertia mama.
