Fiber Optic Integrated Navigation System
Nga waahanga hua
Ko te punaha whakatere whakauru S300D e hangai ana i runga i te gyroscope muka kati-koropiko, te whakatere me te poari whiwhi GNSS teitei-mutunga, na roto i te whakakotahitanga-maha me te otinga whakaterenga algorithm whakatinanatanga hei whakatutuki i nga hiahia o te waea pūkoro reo me te tino tika. nga punaha ine, nga UAV nui, etc.
Ko te mara tono me ine tika mo te waiaro, te upoko me nga korero tuunga.
Nga tauari tono
Kei te punaha he aratau whakatere inertial/satellite me te aratau inersia parakore.
Ko nga amiorangi ka taea e te kaikawe GNSS i roto i te aratau whakatere inertial/satellite integrated navigation aratau korero whakatakotoranga mo te whakatere whakakotahi;te whakaputa i te tuunga otinga inertial i muri i te ngaronga o te waiaro tere tohu, me te tika o te tuunga taumata mita i roto i te wa poto.
Whai muri i te tiimatanga o te aratau inertia parakore, kei a ia te mahi o te inenga waiaro tika, ka taea te whakaputa i te tima okeoke me te upoko, ka taea e te inertia parakore te rapu i te raki.
