Nyob rau hauv peb lub sijhawm, thaum satellite navigation devices tau dhau los ua ib qho chaw, nws zoo li tias kev ploj hauv hav zoov yuav luag tsis yooj yim sua. Txawm li cas los xij, hauv kev xyaum qhov no tsis yog li ntawd. Txhua xyoo, tshwj xeeb tshaj yog thaum lub caij nceb thiab txiv hmab txiv ntoo, EMERCOM cov neeg ua haujlwm yuav tsum tau tshawb nrhiav cov neeg ploj hauv ntau thaj tsam ntawm Russia - tsis yog pej xeem nkaus xwb, tab sis kuj yog cov neeg xav txog hav zoov lawv lub tsev.
GPS-navigator yog qhov tseem ceeb tshaj plaws. Tab sis txhua yam tuaj yeem tshwm sim hauv hav zoov: lub roj teeb tau khiav tawm, poob, tawg, thiab lwm yam. Yog li ntawd, qhov yooj yim magnetic compass yuav los cawm. Qhov no yog ib yam khoom uas tau paub rau noob neej rau ntau tshaj ib puas xyoo. Qhov tseem ceeb yog kom paub siv lub tshuab raj hauv hav zoov.
Lub tshuab sib nqus yog qhov yooj yim tshaj plaws tab sis cov cuab yeej txhim khu kev qha tshaj plaws. Nws lub hauv paus ntsiab lus ntawm kev ua haujlwm yog ua raws li kev sib cuam tshuam ntawm lub ntiaj teb magnetic teb thiab ib rab koob magnetized, uas, rotating ib ncig ntawm nws axis, yog ib txwm nyob rau hauv lub magnetic teb kab.
Hauv paus ntsiab lus, lub compass yooj yim siv. Ib tug tsuas yog tso cov koob sib nqus, thiab tom qab ob peb vib nas this nws muaj nws xiav kawg, uas feem ntau yogzoo li tus xub taub hau, tig mus rau sab qaum teb. Qhov rov qab kawg ntawm tus xub (liab) yuav taw tes rau sab qab teb. Yog li ntawd, yog tias koj sawv ntsug rau sab qaum teb, ces sab hnub tuaj yuav nyob ntawm koj sab xis, thiab sab hnub poob mus rau sab laug. Nws yuav tsum nco ntsoov tias nyob ze cov kab hluav taws xob lossis kev tsheb ciav hlau (nrog rau thaj chaw ntawm cov hlau nplaum sib nqus), cov ntawv nyeem ntawv yuav raug cuam tshuam.
Txhua tus, tsis hais poj niam txiv neej lossis hnub nyoog, tuaj yeem pom lawv tus kheej nyob rau hauv qhov xwm txheej uas lawv yuav tsum tau txiav txim siab lawv qhov chaw thiab kev taw qhia ntawm kev txav, thiab yog li kev paub yuav ua li cas kawm siv lub tshuab ntsuas tsis ua mob rau leej twg.
Tshuaj xyuas cov cuab yeej ua haujlwm
Thaum mus rau ntuj thiab rov hais dua yuav ua li cas siv lub compass hauv hav zoov, koj yuav tsum paub tseeb tias nws ua haujlwm. Rau qhov no koj xav tau:
- Tso lub compass rau ntawm ib theem.
- Cia tus xub nqis los.
- Nqa cov khoom siv hlau mus rau lub compass kom tsis txhob sib npaug ntawm rab koob, thiab mam li tshem cov khoom sai sai.
- Ua kom tus xub rov qab los rau nws txoj haujlwm qub. Yog tias qhov no tsis tshwm sim, koj siv tsis tau cov cuab yeej zoo li no.
Yuav ua li cas siv lub ntsuas phoo hauv thaj teb
Ua ntej mus rau hauv hav zoov:
- Ua ntej tshaj plaws, koj yuav tsum xaiv rau koj tus kheej cov chaw tsim khoom uas yuav pab koj nrhiav txoj hauv kev rov qab rau yav tom ntej. Hauv lwm lo lus, koj yuav tsum "txuas" rau thaj chaw.
- Cov khoom tawm (txoj kev, kev tshem tawm, kab hluav taws xob, thiab lwm yam) yuav tsum raug xaiv ua thaj chaw, uas koj tuaj yeem mus rau txhua qhov chaw, tab sistsuas yog ntawm txoj cai kaum.
- Tom qab qee qhov kev ncua deb ntawm thaj av kom nws nyob hauv kab ntawm qhov pom, koj yuav tsum tig mus rau fim nws, khaws lub compass thiab tso xub. Tom qab nws nres rotating, tig lub cev ntawm lub cuab yeej nyob rau hauv ib tug kab rov tav dav hlau kom cov xub taw tes nrog nws xiav kawg rau inscription "C" ("N"), thiab lub liab kawg rau "S" ("S").
- Ntawm lub ntsuas ntsuas, txiav txim siab cov kev taw qhia hauv qib mus rau qhov chaw xaiv tseg (koj tuaj yeem ua nws pom lossis nrog kev pab ntawm qee yam khoom, hais, twig). Qhov no yog qhov kev taw qhia uas koj yuav tsum tau rov qab los - nws yuav tsum nco ntsoov. Tam sim no koj tuaj yeem nkag mus rau hauv hav zoov ntawm qhov sib txawv ntawm qhov ntsuas ntawm 180 degrees.
Yuav ua li cas siv lub ntsuas phoo hauv hav zoov kom rov qab mus rau qhov chaw:
- Tig lub compass nyob rau hauv koj txhais tes kom cov kab mob pom kev hla mus rau hauv nruab nrab ntawm lub compass thiab lub azimuth muab.
- Tshuav tus xub thiab, tig ib ncig ntawm nws qhov axis, ua kom nws coincide nrog rau sab qaum teb-sab qab teb kev taw qhia.
- Tsiv mus rau qhov kev taw qhia koj saib yog taw qhia.
Yuav kom tsis txhob poob, nws yog qhov zoo tshaj rau ncua sij hawm hloov txoj kev ntawm txoj kev - ob qho tib si thaum tsiv mus rau hauv hav zoov thiab thaum tawm mus.
Txawm tias koj paub siv lub ntsuas phoo hauv hav zoov, koj yuav tsum ua raws li txoj cai yooj yim - ua ntej koj mus rau thaj chaw tsis paub, koj yuav tsum xav ua ntej yuav tawm ntawm nws li cas. Tsis muaj teeb meem koj yuav tsum deviate los ntawm lub hom phiajtxoj kev. Yog tias qhov no tshwm sim, tsis txhob poob siab. Koj yuav tsum ua siab ntev nkag siab txog qhov xwm txheej thiab txiav txim siab kom raug.
