Hom 70 Fiber Strapdown Inertial Navigation System
Khoom piav qhia
FS70 Fiber Optic Integrated Navigation System, lub xeev-ntawm-tus-kos duab daws teeb meem uas seamlessly combines nqi-zoo thiab kev ua tau zoo tshwj xeeb.Qhov kev txiav-ntug no yog tsim los ntawm kev kaw-kab fiber ntau optic gyroscope, accelerometer, thiab high-end GNSS txais board, kom ntseeg tau meej thiab txhim khu kev ntsuas.
Los ntawm kev siv cov kev sib txuas ntawm ntau lub sensor fusion thiab navigation algorithms, FS70 system ua tiav qhov tsis sib xws hauv kev ntsuas tus cwj pwm, nqe lus, thiab cov ntaub ntawv qhia chaw.Nws yog tsim tshwj xeeb los ua kom haum rau cov kev xav tau nruj ntawm nruab nrab mus rau qhov siab tshaj qhov ntsuas lub xov tooj ntawm tes, cov tsheb loj tsis muaj neeg tsav dav hlau (UAVs), thiab ntau yam kev siv.
Nrog rau FS70 Fiber Optic Integrated Navigation System, koj tuaj yeem qhib qib tshiab ntawm qhov tseeb thiab kev ntseeg siab hauv koj txoj haujlwm.Nws muaj ntau yam xwm txheej thiab kev sib koom ua ke tsis sib haum ua rau nws yog ib qho khoom siv tsis tseem ceeb rau kev lag luam xws li kev soj ntsuam, daim ntawv qhia, kev paub txog tej thaj chaw deb, thiab lwm yam.
Ua rau yav tom ntej ntawm kev siv tshuab navigation nrog FS70 Fiber Optic Integrated Navigation System thiab txhawb koj qhov kev ua tau zoo rau qhov siab tshiab.
MAIN FUNCTION
Lub kaw lus nta ib qho ua ke inertial / satellite navigation hom nrog rau hom ntshiab inertial.
Hauv kev sib xyaw ua ke inertial / satellite navigation hom, GNSS receiver captures satellite positioning cov ntaub ntawv uas yuav siv tau rau kev sib xyaw navigation.Hom no outputs carrier pitch, yob, nqe lus, txoj hauj lwm, ceev, thiab lub sij hawm cov ntaub ntawv.Nyob rau hauv qhov kev tshwm sim ntawm lub teeb liab poob, lub inertia-xav txoj hauj lwm, tshaj tawm thiab tus cwj pwm yog tso zis.Lub suab thiab yob yuav tsum tau calibration meej nrog rau lub sij hawm luv luv tuav kev ua haujlwm thiab tuaj yeem ua tiav qhov ntsuas qhov ntsuas qhov tseeb hauv lub sijhawm luv.
Hom ntshiab inertial (uas yog, GPS fusion yeej tsis tau ua tiav tom qab lub hwj chim, thiab yog tias nws poob xauv dua tom qab fusion, nws yog rau kev sib xyaw navigation hom) muaj qhov ntsuas tus cwj pwm zoo thiab tuaj yeem tso tawm suab, yob, thiab nqe lus.Ntshiab inertia tuaj yeem ua qhov kev tshawb nrhiav sab qaum teb zoo li qub.
