Fiber Optic Integrated Navigation System
Oloa Fa'ailoga
O le fiber optic integrated navigation system S300D e faʻavae i luga o le taugofie o le tapunia o le fiber optic gyroscope, accelerometer ma le maualuga o le GNSS receiving board, e ala i le tele-sensor fusion ma le faʻaogaina o faʻataʻitaʻiga algorithm faʻatinoga e fetaui ma manaʻoga o le telefoni feaveaʻi ma le maualuga. faiga fua, UAV tetele, ma isi.
O le fanua talosaga e manaʻomia le fua saʻo o uiga, ulutala ma faʻamatalaga tulaga.
Tala fa'atatau
O le faiga o lo'o i ai le tu'ufa'atasiga o le fa'aogaina o le inertial/satelite mode ma le mama inertial mode.
O satelite e mafai ona maua e le GNSS receiver i le inertial/satellite integrated navigation mode faʻamatalaga faʻatulagaina satelite mo faʻasalalauga tuʻufaʻatasia;tulaga fofo inertial output pe a uma le leiloa faailo saoasaoa uiga, ma mita-tulaga sa'o tulaga tulaga i se taimi puupuu.
A mae'a ona amata le tulaga mama inertia, o lo'o i ai le galuega o le fuaina o uiga sa'o ma e mafai ona gaosia le ta'avale ma le ulutala, e mafai e le inertia mama ona su'e i matu.
