Nyob rau hauv lub sij hawm ntawm kev siv technology tshiab strides, navigation systems tau tshwm sim raws li lub hauv paus ncej, tsav tsheb ntau yam, tshwj xeeb tshaj yog nyob rau hauv precision-tseem ceeb sectors. Txoj kev taug kev los ntawm rudimentary celestial navigation mus rau sophisticated Inertial Navigation Systems (INS) epitomizes tib neeg lub unyielding endeavors rau kev tshawb nrhiav thiab pinpoint raug. Qhov kev tshuaj xyuas no nkag mus tob rau hauv INS cov kev sib txuas ntawm cov tshuab, tshawb xyuas cov cuab yeej siv hluav taws xob ntawm Fiber Optic Gyroscopes (FOGs) thiab lub luag haujlwm tseem ceeb ntawm Polarization hauv Kev Tswj Fiber Loops.
Part 1: Txiav txim siab Inertial Navigation Systems (INS):
Inertial Navigation Systems (INS) sawv tawm raws li kev tswj hwm kev tswj hwm kev pabcuam, suav nrog lub tsheb txoj haujlwm, kev taw qhia, thiab kev tshaj tawm, ywj siab ntawm cov lus qhia sab nraud. Cov tshuab no ua kom sib haum xeeb ntawm cov lus tsa suab thiab kev sib hloov sensors, sib txuas ua ke nrog cov qauv kev suav rau thawj zaug tshaj tawm, txoj hauj lwm, thiab kev taw qhia.
Ib qho archetypal INS encompasses peb lub ntsiab lus tseem ceeb:
· Accelerometers: Cov ntsiab lus tseem ceeb no sau npe lub tsheb txoj kab nrawm, txhais cov lus tsa suab rau hauv cov ntaub ntawv ntsuas.
· Gyroscopes: Ib qho tseem ceeb rau kev txiav txim siab angular tshaj tawm, cov khoom no yog qhov tseem ceeb rau kev taw qhia.
· Computer Module: Lub paj hlwb ntawm INS, ua cov ntaub ntawv ntau yam kom tau txais txiaj ntsig ntawm txoj haujlwm ntawm lub sijhawm tiag tiag.
INS txoj kev tiv thaiv rau kev cuam tshuam sab nraud ua rau nws tseem ceeb hauv kev tiv thaiv kev lag luam. Txawm li cas los xij, nws cuam tshuam nrog 'drift' - qhov tseeb maj mam lwj, xav tau cov kev daws teeb meem zoo li sensor fusion rau kev ua yuam kev mitigation (Chatfield, 1997).
Ntu 2. Kev Ua Haujlwm Dynamics ntawm Fiber Optic Gyroscope:
Fiber Optic Gyroscopes (FOGs) tau tshaj tawm lub sijhawm hloov pauv hauv kev hloov pauv, siv lub teeb cuam tshuam. Nrog rau qhov tseeb ntawm nws cov tub ntxhais, FOGs yog qhov tseem ceeb rau lub tsheb aerospace 'stabilization thiab navigation.
FOGs khiav lag luam ntawm Sagnac nyhuv, qhov twg lub teeb, traversing nyob rau hauv txee cov lus qhia nyob rau hauv ib tug rotating fiber coil, manifests ib theem hloov correlating nrog rotational tus nqi hloov. Qhov no nuanced mechanism txhais mus rau qhov tseeb angular tshaj tawm metrics.
Cov khoom tseem ceeb muaj xws li:
· Lub teeb Source: Lub inception point, feem ntau yog laser, pib lub teeb coherent taug kev.
· Fiber Coil: Ib coiled optical conduit, prolongs lub teeb lub trajectory, li no amplifying lub Sagnac nyhuv.
· Photodetector: Cov khoom tivthaiv no pom cov qauv sib cuam tshuam ntawm lub teeb.
Ntu 3: Qhov tseem ceeb ntawm Polarization tuav Fiber Loops:
Polarization Maintaining (PM) Fiber Loops, quintessential rau FOGs, paub tseeb tias lub teeb pom kev zoo polarization ntawm lub teeb, qhov tseem ceeb ntawm kev cuam tshuam cov qauv precision. Cov fibers tshwj xeeb no, sib ntaus sib tua polarization hom dispersion, txhawb FOG rhiab heev thiab cov ntaub ntawv tseeb (Kersey, 1996).
Kev xaiv PM fibers, dictated los ntawm kev ua haujlwm exigencies, lub cev cwj pwm, thiab kev sib haum xeeb, cuam tshuam rau kev ntsuas kev ua tau zoo.
Ntu 4: Daim Ntawv Thov thiab Cov Ntaub Ntawv Pov Thawj:
FOGs thiab INS pom resonance thoob plaws ntau daim ntawv thov, los ntawm orchestrating unmanned aerial forays kom ntseeg tau tias cinematic stability nyob rau hauv ib puag ncig unpredictability. Ib daim ntawv pov thawj rau lawv txoj kev ntseeg tau yog lawv txoj kev xa mus rau NASA lub Mars Rovers, ua kom yooj yim rau kev ua haujlwm tsis muaj kev nyab xeeb (Maimone, Cheng, thiab Matthies, 2007).
Kev lag luam trajectories kwv yees ib qho kev loj hlob zoo rau cov thev naus laus zis no, nrog rau kev tshawb fawb vectors tsom rau kev tiv thaiv kev tiv thaiv kab mob, kev ua kom zoo, thiab kev yoog raws (MarketsandMarkets, 2020).
