Marine Satellite Speed ​​Log SDME

Satellite ceev cav tau dhau los ua qhov tseem ceeb hauv kev lag luam marine nyob rau ob peb xyoos dhau los hauv kev saib xyuas lub nkoj ceev thiab kev nyob deb. Lawv kuj tseem hu ua Cov Khoom Siv Ntsuas Ceev thiab Kev Ntsuas, lossis SDME.
Yog li dab tsi yog satellite ceev cav thiab lawv ua haujlwm li cas? Qhov tseem ceeb, cov khoom siv no siv cov teeb liab satellite los txiav txim siab lub nkoj ceev thiab qhov deb tau taug kev los ntawm dej. Lawv ua hauj lwm los ntawm emitting ib lub teeb liab los ntawm lub nkoj uas yog ces khaws thiab xav rov qab los ntawm satellites. Lub cav ceev ces ntsuas lub sij hawm nws yuav siv sij hawm rau lub teeb liab taug kev los ntawm lub nkoj mus rau lub satellite thiab rov qab los, thiab siv qhov no los xam lub nkoj ceev thiab nyob deb li cas mus.
Cov khoom no yog ib qho cuab yeej navigation los ntsuas lub nkoj ceev thiab cov voyage. Nws muab cov ntaub ntawv qhia meej txog txoj haujlwm thiab cov ntaub ntawv ceev thiab cov lus qhia rau cov tswv nkoj, thiab paub txog cov zaub thiab ceeb toom ntawm lub nkoj cov ntaub ntawv kev txav mus los.
Cov txiaj ntsig:
Ua ntej, lawv yog qhov tseeb thiab txhim khu kev qha, muab cov ntaub ntawv hauv lub sijhawm ntawm lub nkoj ceev thiab kev mus deb. Qhov no tuaj yeem yog qhov tseem ceeb hauv ntau qhov xwm txheej, xws li thaum taug kev los ntawm kev thauj khoom tsis khoom lossis thaum huab cua phem. Nws tseem tuaj yeem pab cov tuam txhab xa khoom kom txhim kho lawv txoj hauv kev thiab txo qis kev siv roj, nrog rau muab cov ntaub ntawv tseem ceeb rau kev tshaj tawm thiab ua raws cov hom phiaj.
Tsis tas li ntawd, satellite ceev cav yog ib qho yooj yim rau nruab thiab tswj, thiab tuaj yeem ua ke nrog lwm cov tshuab onboard. Qhov no txhais tau hais tias cov neeg tsav nkoj tuaj yeem nkag mus rau ntau yam ntawm cov ntaub ntawv thiab cov ntaub ntawv nyob rau hauv ib qho chaw, ua kom yooj yim navigation thiab saib xyuas cov txheej txheem.

Khoom nta:
Kev tshawb fawb algorithm, kom meej meej decompose cov ntaub ntawv ntawm transverse motion ntawm hneev nti thiab stern.
Tsis muaj cov khoom siv kho tshuab, kev tu-dawb, tsis muaj nqi rov ua dua, yooj yim installation
Ntau NMEA0183 outputs muab cov ntaub ntawv qhia txog kev xa nkoj kom raug thiab meej rau radar, plotter, tsheb kauj vab, ntses nrhiav, sonar thiab lwm yam khoom siv hauv nkoj hiav txwv.
Txhawb CAN tso zis, nqe lus, txoj hauj lwm, ceev, mileage thiab tus cwj pwm tso zis.
Cov cuab yeej tsis cuam tshuam los ntawm dej kub thiab ntsev, thiab yuav tsum tau tiv thaiv cov cua daj cua dub thiab cua daj cua dub.
Kev xaiv 7 nti xim kov lub vijtsam zaub, muab SDME thiab compass dual hom, cov ntaub ntawv nkag siab ntau dua, cov khoom siv yooj yim dua.
