Ib qho azimuth yog cov kev taw qhia ntsuas hauv degrees clockwise los ntawm sab qaum teb ntawm lub voj voog azimuth. Lub voj voog azimuth muaj 360 degrees. cuaj caum degrees sib raug rau sab hnub tuaj, 180 degrees yog sab qab teb, 270 degrees sab hnub poob, thiab 360 degrees thiab 0 degrees kos rau sab qaum teb.
Azimuth yog lub tswv yim ntuj heev. Nws sib raug rau lub ntuj xav ntawm "lub kaum sab xis ntawm ib qho kev taw qhia nrog rau sab qaum teb". Txawm li cas los xij, txhais nws hauv 3d yuav tsum muaj ob peb lo lus ntxiv.
Azimuth yog lub kaum sab xis ua nrog cov kab hlau nplaum qaum teb ntawm lub ntiaj teb. Nyob rau hauv lwm yam lus nws yog lub kaum sab xis cim rau ntawm koj lub compass nrog ib yam khoom nyob rau hauv lub qab ntug.
Nyob rau hauv lwm yam lus tseem, yog hais tias koj sawv nyob rau hauv nruab nrab ntawm ib tug tiaj los yog ntawm lub hiav txwv, qhov twg koj yuav saib tau ntawm ib tug taw tes ntawm lub qab ntug, thiab yog hais tias koj lub compass yog drected nrog nws 0 ntawm lub magnetic xub, lub azimuth. ntawm txhua lub qab ntug taw tes yog lub kaum sab xis uas koj tuaj yeem nyeem ntawm qhov ntsuas ntawm lub compass.
Vam tias qhov no yog qhov tseeb. Nws yog qhov yooj yim tshaj plaws los qhia, tab sis me ntsis ntxiv me ntsis los piav nrog cov lus.
Daim duab hauv qab no qhia lub hnub qub raws li nws tau txhais los ntawm nws qhov azimuth thiab qhov siab (tseem hu ua qhov siab).
Azimuth nyob rau hauv ib qho kev siv thav duab yog ib lub voj voog tag nrho ntawm kev taw qhia, clockwise thaum saib, thiab nrog rau xoom taw tes feem ntau muab rau qee yam sab qaum teb. Txawm hais tias koj tab tom ua haujlwm ntawm ib puag ncig lossis lub dav hlau, nws ua haujlwm li cas. Feem ntau, peb cov neeg siv degrees, feeb thiab vib nas this rau lub kaum sab xis, raws li qhov ntawd yog ib txwm muaj.
Qhov twg sab qaum teb raug xaiv rau xoom yog nyob ntawm tus neeg ua haujlwm, tab sis nws yuav tsum tau teev tseg. Tej zaum nws yuav muaj tseeb rau sab qaum teb, sib nqus sab qaum teb, sib nqus sab qaum teb ntawm qee hnub tshwj xeeb, kab sib chaws sab qaum teb (ntawm uas yuav luag ib qho kev xaiv tsis kawg) lossis lwm yam.
Hauv Teb Chaws Asmeskas, koj tuaj yeem muaj qhov 'arbitrary azimuth' qhov twg tus xoom yog kiag li arbitrary, uas yog ib yam dab tsi ntawm ib tug contradiction. Nyob rau hauv ib feem ntawm lub ntiaj teb no qhov twg lub quarter-lub voj voog bearings tau poob rau hauv kev tsis siv, lub sij hawm 'bearings' yuav siv tau rau qhov no 360 degree siv nrog ib tug arbitrary xoom, tsawg kawg ntawm cov neeg soj ntsuam. Ntawm cov navigators, 'cov kabmob' muaj lub ntsiab lus txawv me ntsis.
Yog li yog tias koj siv azimuths nrog degrees, sab qaum teb yog 0 degree, sab hnub tuaj yog 90 degree, sab qab teb yog 180 degree thiab sab hnub poob yog 270 degree. Koj tuaj yeem tau txais azimuths los ntawm daim ntawv qhia lossis daim ntawv qhia siv 360 degree protractor nrog xoom raws li kev coj ntawm sab qaum teb ntawm daim ntawv qhia lossis daim ntawv qhia. Ntawm cov kab kos nautical, feem ntau muaj tsawg kawg yog ib lub compass sawv, thiab koj tuaj yeem hloov ib qho kev taw qhia ntawm daim duab mus rau lub compass sawv rau kev ntsuas azimuth siv cov thawj coj sib luag. Qhov no tsis tas yuav tsum txheeb tawm cov protractors.
Lub voj voog azimuth uas tau ua qhov kev pabcuam sawv ntsug rau ntau xyoo, ua haujlwm tseem ceeb hauv kev taw qhia thiab paub zoo tias tsis muaj kev piav qhia yog xav tau. Txawm hais tias muaj rugged txaus los tiv thaiv kev siv tib yam, kev sib tsoo los yog siv tsis raug yuav ua rau muaj kev cuam tshuam. Thaum tawm ntawm kev hloov kho qhov txhaum yog qhov nyuaj rau kev txiav txim siab thiab kho nrog cov chaw pom hauv nkoj nkoj. Ib qho yuam kev nyob rau hauv lub voj voog fittings cuam tshuam rau azimuths, cuam tshuam rau cov chav kawm nteg los ntawm tus nqi ntawm qhov yuam kev. Raws li qhov piv txwv ntawm qhov kev sib raug zoo no, qhov kev paub ntawm ib lub nkoj tau muab. Lub nkoj no thaum taug kev ntev muaj qhov sib xws, tsis suav nrog txog kaum mais ib hnub. Raws li ib hnub dhau ib hnub dhau los nrog ib txheej ntawm kwv yees li qub, nws tau xav tias lub voj voog azimuth tsis hloov. Kev sib piv nrog lwm lub voj voog tsim qhov tseeb tias tsis muaj leej twg pom zoo. Tom qab ntawd thaum muaj ib lub sij hawm kom muaj lub voj voog xyuas nws tau pom tias yuav tawm ntawm ib tug degree thiab ib nrab, uas yuam kev yuav luag raws nraim accounted rau cov teeb pom kev zoo.
Ntau tus navigators xa cov voj voog azimuth mus rau Naval Observatory lossis mus rau lub khw muag khoom siv tub rog rau kev kuaj xyuas thaum muaj sijhawm txaus. Qee lub nkoj kho tam sim no tau nruab los kho cov voj voog. Yog tias nws tuaj yeem ua qhov kev kuaj xyuas zoo ntawm lub nkoj nkoj, ntau qhov haujlwm no tuaj yeem zam tau.
Qhov kev kuaj pom feem ntau yog kuaj lub azimuth los ntawm lub hnub tsom iav tiv thaiv ib qho ncaj qha azimuth nrog rau cov av hauv av. Qhov no kuj yog qhov ntsuas lub khw muag khoom, tab sis thaum ua tiav ntawm lub nkoj nkoj nws tsis yog qhov tseeb raws li nws xav tau qhov kev xav tias cov vanes hauv av tau hloov kho. Nws yog qhov tseeb hais tias cov vanes lawv tus kheej tsis yog li raug derangement raws li lub hnub-daim iav prism kev npaj, tab sis qhov kev ntsuam xyuas feem ntau yuav tsum tau siv daim iav tsaus nti thiab qhov kawg yuav raug derangement ntau dua li lwm qhov ntawm lub voj voog. Nyob rau hauv ib lub khw muag khoom, kev hloov pauv ntawm cov vanes terrestrial thiab daim iav tsaus tuaj yeem kuaj xyuas thiab tom qab hnub-daim iav tsom iav yog qhov tseeb.
Thaum nyeem thawj zaug, cov lus piav qhia yuav tshwm sim los ntawm kev txawj ntse, tab sis txhua tus nyeem ntawv uas txaus siab los rhuav tshem lub voj voog azimuth rau kev siv thaum nyeem ntawv yuav pom tias cov txheej txheem nkag siab yooj yim.
Nyob rau hauv cov ntaub ntawv yooj yim tshaj plaws, lub voj voog azimuth yog ua los ntawm lub suab nrov uas cim nrog tus xub uas tau kos rau lub ntiaj teb sab qaum teb. Nrog rau ib qho ntawm cov ntaub ntawv no, koj tuaj yeem tau txais qhov kwv yees kwv yees ntawm koj cov kabmob. Txhua lub compass tsim nyog nqa yuav suav nrog cov qhab nia qib kom paub meej dua. Cov cim ntau dua txhais tau tias muaj tseeb dua, thiab peb pom zoo kom nrhiav cov tub rog-style compass uas qhia tau 360 degrees.
Tsis txhob thab mus nqa nrog feeb thiab vib nas this (60 feeb ib degree, 60 vib nas this ib feeb). Ib txoj kab ruaj khov yuav qhia txog lub cev lub cev kev taw qhia nyob rau hauv kev sib piv rau lub floating dial.
Vim tias compasses yog cov cuab yeej sib nqus, nws yog ib qho tseem ceeb uas koj yuav tsum nco ntsoov xyuas koj ib puag ncig rau tej yam uas tuaj yeem cuam tshuam rau lawv txoj haujlwm. Cov khoom siv hlau me me npaum li rab phom tuaj yeem pov koj cov ntawv nyeem compass. Cov tsheb thiab cov kab hluav taws xob tuaj yeem cuam tshuam tshwj xeeb. Nyob deb ntawm koj tus kheej los ntawm cov khoom hlau loj kom tau txais kev nyeem ntawv tseeb dua.
Thaum koj tua koj azimuth, taug kev ncaj qha rau nws yog qhov ua tau zoo - tab sis tedious (thiab qee zaum ua tsis tau) - thev naus laus zis. Yog tias koj xaiv txoj kev no, xaiv cov ntsiab lus nyob ze lossis txwv kev ncig mus txog li kaum paces ntawm qhov rov pom dua tuaj yeem txhim kho qhov tseeb. Yuav tsum paub txog qhov xwm txheej zoo li qhov chaw nqes hav thiab hauv av li cas cuam tshuam rau koj lub rooj vag.
Peb pom zoo kom siv kev sib txuas ntawm kev nyeem ntawv compass thiab struts struts rau kev taw qhia. Pib los ntawm kev txheeb xyuas cov khoom ruaj khov raws koj lub azimuth thiab taug kev mus rau nws siv txoj hauv kev zoo tshaj plaws. Yog tias koj tuaj yeem pom qhov nruab nrab txhim khu kev qha, koj tuaj yeem zam kev hla dej sib sib zog nqus thiab tawm tsam los ntawm cov kab hauv qab tuab kom txav mus rau hauv txoj kab ncaj nraim.
Hmo ntuj navigation tuaj yeem ua rau nws ua tsis tau lossis ua tsis tau zoo los siv qhov pom ntawm koj lub compass nrog txoj kev sib piv-rau-cheek. Thaum zoo li no, koj yuav tsum tuav lub compass tiv thaiv koj lub cev nyob rau hauv qab ntawm koj rib tawb thiab perpendicular rau koj lub cev. Cov cim luminous yuav cia koj tau txais koj cov kabmob thiab taw qhia koj mus rau qhov raug. Nco ntsoov khaws lub compass kom nruj rau koj lub cev thiab tig siv koj txhais taw, tsis yog koj lub duav.
Magnifying iav
Feem ntau lub voj voog azimuth yog me dua li ntawm koj txhais tes, thiab kos 360 degrees ntawm lub voj voog uas me me tuaj yeem ua rau cov ntawv nyeem nyuaj. Lub lens magnifying yuav cia koj tau txais kev nyeem ntawv tseeb dua.
Kev pom qhov system
Yog tias koj npaj rau kev cia siab rau lub compass rau lub neej tiag tiag navigation, koj yuav tsum tau ua kom zoo dua li qhov yooj yim floating dial thiab index kab. Sighting systems tso cai rau koj pom qhov koj xav tau kev taw qhia (lub npe hu ua tua ib qho azimuth) los ntawm kev ua kom pom cov duab pem hauv ntej thiab nram qab los txheeb xyuas qhov tseeb ntawm qhov kev ncua deb uas koj xav tau mus txog kev mus rau qhov raug.
Bezel nplhaib
Lub nplhaib bezel yuav cia koj teem koj qhov kev kawm ib zaug rau yav tom ntej siv thiab tiv thaiv koj los ntawm kev ua yuam kev kim tom qab. Tub rog compasss siv lub nplhaib bezel uas txav peb degrees nrog txhua nias. Piv txwv li, txhawm rau tua 30-degree azimuth, koj yuav tig koj lub nplhaib bezel kaum clicks counter-clockwise. Los ntawm qhov taw tes rau pem hauv ntej, kab ntawm koj lub nplhaib bezel txoj kab luv luv nrog lub xub sib nqus yuav tsom koj cov duab pom ncaj qha mus rau 30 degrees.
Luminous cim
Lub compass uas ci hauv qhov tsaus ntuj tuaj yeem siv tau thaum hmo ntuj lossis hauv lwm qhov xwm txheej tsis pom kev. Tub rog compasss siv tritium, uas tsis tas yuav raug them los ntawm kev nthuav tawm lub teeb, muab cov cim luminous ntawm cov ntsiab lus tseem ceeb xws li sib nqus sab qaum teb, lub nplhaib bezel, thiab pom pem hauv ntej los pab thaum hmo ntuj navigation.
ntiv tes xoo
Lub voj ntiv tes xoo yuav pab koj tuav koj lub compass ruaj khov thaum tua azimuth. Siv lub compass kom yog yuav tsum tau precision, yog li siv tag nrho cov kev pab koj tuaj yeem tau txais.
Lub nraub qaum azimuth yog ib qho kev kwv yees ntawm azimuth los ntawm keeb kwm mus rau sab nraud ntawm lub voj voog azimuth. Muaj 360 degrees nyob rau hauv lub voj voog azimuth, yog li qhov kev coj rov qab yuav yog 180 degrees (ib nrab ntawm 360 degrees) los ntawm azimuth.
A rov qab azimuth yog xam los ntawm kev ntxiv 180 degree rau lub azimuth thaum lub azimuth tsawg dua 180 degree, los yog rho tawm 180 degree ntawm lub azimuth yog tias nws yog ntau tshaj 180 degree. Piv txwv li, yog azimuth yog 320 degree, lub nraub qaum azimuth yuav yog 320 degree - 180 degree=140 degree . Yog tias azimuth yog 30 degree, lub nraub qaum azimuth yuav yog 180 degree + 30 degree=210 degree .
Backsighting yog ib txoj kev pom uas siv azimuth nyeem ntawv rov qab. Backsighting siv lub azimuth pom thiab tig nws ib ncig los nrhiav txoj hauv kev rov qab mus rau qhov pib pib.
