National Marine Electronics Association (NMEA) yog lub koom haum kev lag luam uas tau tsim cov txheej txheem kev sib txuas lus ntawm cov khoom siv hluav taws xob hauv hiav txwv. Cov txheej txheem no yog siv los ua kom cov ntaub ntawv sib koom ntawm cov khoom siv xws li GPS receivers, chartplotters, fishfinders, thiab radar systems.
Txhawm rau nyeem GPS cov ntaub ntawv, NMEA raws tu qauv siv cov kab lus qauv uas tau kis los ntawm GPS txais mus rau lwm yam khoom siv. Cov kab lus no muab cov ntaub ntawv ntawm ntau yam ntaub ntawv suav nrog latitude, longitude, ceev, chav kawm, thiab lwm yam ntaub ntawv tseem ceeb navigational.
NMEA raws tu qauv siv cov qauv kev sib txuas lus uas muaj cov cim ASCII. Qhov no ua rau nws yooj yim rau cov khoom siv sib txuas lus nrog ib leeg vim tias cov ntawv xov xwm sib xws thiab sib xws.
Txhawm rau kom ntseeg tau tias cov cuab yeej muaj peev xwm sib txuas lus nrog ib leeg, NMEA raws tu qauv kuj suav nrog cov txheej txheem rau kev tsim cov ntaub ntawv, tus nqi sib kis, thiab kev tshawb pom qhov yuam kev. Qhov no yuav pab tiv thaiv kev ua yuam kev thiab xyuas kom meej tias cov ntaub ntawv kis tau raug ntawm cov khoom siv.
