High-Precision Stable Platform: Nrog nws qhov tshwj xeeb kev ruaj ntseg thiab precision, FS100 yog ib qho zoo meej haum rau high-precision ruaj khov platform daim ntaub ntawv, kom ntseeg tau tias kev ua tau zoo thiab raug.
Muaj kev paub txog qhov kawg ntawm kev ntsuas siab thiab tswj nrog FS100, kev daws teeb meem tsim los ua kom tau raws li qhov xav tau tshaj plaws hauv ntau qhov kev lag luam.
MAIN FUNCTION
Lub kaw lus tau ua ke inertial / satellite navigation hom thiab ntshiab inertial hom.
Inertial guide built-in GNSS board, thaum GNSS zoo inertial phau ntawv tuaj yeem ua ke nrog GNSS rau kev navigation, thiab muab txoj haujlwm ua ke, qhov siab, ceev, tus cwj pwm, nqe lus, acceleration, angular tshaj tawm thiab lwm yam navigation tsis rau tus neeg siv, thaum outputting GNSS txoj haujlwm, qhov siab, ceev thiab lwm yam ntaub ntawv.
Thaum GNSS tsis raug, nws tuaj yeem nkag mus rau hom ntshiab inertial (piv txwv li, nws tsis tau ua GPS fusion tom qab lub hwj chim rau, thiab yog tias nws poob xauv dua tom qab fusion, nws yog nyob rau hauv kev sib xyaw navigation hom) Tom qab pib, nws muaj qhov ntsuas tus cwj pwm raug. muaj nuj nqi, tuaj yeem tso tawm suab thiab dov taub hau, thiab ntshiab inertial tuaj yeem ua rau sab qaum teb nrhiav.
Lub luag haujlwm tseem ceeb suav nrog
l kev pib ua haujlwm ua haujlwm: inertial qhia lub zog rau thiab tos rau cov ntaub ntawv satellite yog siv tau, lub satellite siv tau rau 300s kev sib dhos, kev sib dhos ua tiav tom qab hloov mus rau kev sib xyaw navigation xeev inertial qhia;
l ua ke navigation muaj nuj nqi: tam sim ntawd tom qab thawj zaug ua ke mus rau hauv lub xeev navigation ua ke, inertial kev taw qhia siv lub sab hauv GNSS pawg thawj coj saib ua ke navigation, yuav daws tau tus cab kuj ceev, txoj hauj lwm thiab tus cwj pwm thiab lwm yam navigation ntaub ntawv;
l kev sib txuas lus muaj nuj nqi: daim ntawv qhia inertial tuaj yeem tso tawm cov ntaub ntawv ntsuas kev ntsuas inertial rau sab nraud raws li txoj cai;
l nrog lub peev xwm los txhim kho software hauv qhov chaw ntawm lub nkoj: cov software navigation tuaj yeem hloov kho los ntawm qhov chaw nres nkoj serial;
l nrog lub peev xwm tshawb pom tus kheej, thaum lub kaw lus tsis ua haujlwm, tuaj yeem xa cov ntaub ntawv tsis raug, ceeb toom rau cov khoom siv;
l nrog wobble alignment muaj nuj nqi.
