IFiber Optic Integrated Navigation System
Iimpawu zeMveliso
I-fiber optic edibeneyo yokukhangela inkqubo ye-S300D isekelwe kwiindleko ezisebenzayo ezivaliweyo ze-fiber optic gyroscope, i-accelerometer kunye ne-high-end ye-GNSS yokufumana ibhodi, ngokusebenzisa i-multi-sensor fusion kunye nokuphunyezwa kwesisombululo se-algorithm ukuhlangabezana neemfuno zeselula ephakathi kunye nephezulu. iinkqubo zokulinganisa, ii-UAV ezinkulu, njl.
Intsimi yesicelo idinga umlinganiselo ochanekileyo wesimo sengqondo, isihloko kunye nolwazi lwendawo.
Iimeko zesicelo
Inkqubo ine-inertial edibeneyo ye-inertial / imowudi yokuhamba nge-satellite kunye nemodi ecocekileyo ye-inertial.
Iisathelayithi ezinokufunyanwa ngumamkeli we-GNSS kwimo engasebenziyo/yesathelayithi ehlanganisiweyo yokukhangela imo yolwazi olukumiselo lwesathelayithi lokuhamba oludibeneyo;isiphumo sesisombululo se-inertial isikhundla emva kokulahlekelwa isimo sengqondo sesantya somqondiso, kunye nokuchaneka komgangatho wemitha ngexesha elifutshane.
Emva kokuba imowudi ye-inertia esulungekileyo iqalisiwe, inomsebenzi wokulinganisa isimo sengqondo esichanekileyo kwaye inokukhupha i-pitch rolling kunye nesihloko, inertia ecocekileyo inokukhangela emantla.
