Lembani 70 Fiber Strapdown Inertial Navigation System
Mafotokozedwe Akatundu
FS70 Fiber Optic Integrated Navigation System, njira yotsogola yomwe imaphatikiza mosasunthika komanso magwiridwe antchito apadera.Dongosolo lakutsogololi limamangidwa pazitsulo zotsekeka za fiber optic gyroscope, accelerometer, ndi bolodi yolandila ya GNSS yapamwamba kwambiri, kuwonetsetsa miyeso yolondola komanso yodalirika.
Pogwiritsa ntchito kuphatikizika kwa ma sensor ambiri ndi ma aligorivimu oyenda, dongosolo la FS70 limakwaniritsa kulondola kosayerekezeka pakuyesa malingaliro, mutu, ndi chidziwitso cha malo.Idapangidwa kuti ikwaniritse zofunikira zamakina apakati mpaka apamwamba kwambiri oyezera mafoni, magalimoto akuluakulu osayendetsedwa ndi anthu (UAVs), ndi mapulogalamu ena osiyanasiyana.
Ndi FS70 Fiber Optic Integrated Navigation System, mutha kumasula milingo yatsopano yolondola komanso yodalirika pamachitidwe anu.Kusinthasintha kwake komanso kuphatikiza kosasinthika kumapangitsa kuti ikhale chida chofunikira kwambiri m'mafakitale monga kufufuza, kupanga mapu, kuzindikira kutali, ndi zina zambiri.
Dziwani za tsogolo laukadaulo wapanyanja ndi FS70 Fiber Optic Integrated Navigation System ndikukweza magwiridwe anu apamwamba.
NTCHITO YAIKULU
Dongosololi limakhala ndi njira yophatikizira inertial / satellite navigation mode komanso njira yoyera ya inertial.
Mumayendedwe ophatikizika a inertial/satellite navigation, cholandila cha GNSS chimatenga zambiri za satelayiti zomwe zitha kugwiritsidwa ntchito pophatikizana.Njirayi imatulutsa mayendedwe, mpukutu, mutu, malo, liwiro, ndi nthawi.Pakatayika chizindikiro, malo owerengera inertia, liwiro ndi malingaliro amatuluka.Phokoso ndi mpukutu zimafunikira kusanjidwa bwino ndi kosi yogwira kwakanthawi kochepa ndipo imatha kukwaniritsa kulondola kwamamita pakanthawi kochepa.
Njira yoyera ya inertial (ndiko kuti, kuphatikizika kwa GPS sikunachitikepo pambuyo poyatsa, ndipo ngati itayikanso loko pambuyo pa kuphatikizika, ndi ya integrated navigation mode) imakhala ndi ntchito yoyezera malingaliro ndipo imatha kutulutsa mawu, roll, ndi mutu.Inertia yoyera imatha kusaka kosasunthika kumpoto.
