High Frequency (VHF) Cov Khoom Siv: Lub luag haujlwm luv luv -cov haujlwm sib txuas lus, suav nrog thaj tsam li 30 nautical mais. Channel 16 ua haujlwm raws li kev mob siab rau thoob ntiaj teb kev sib txuas lus kev ntxhov siab thiab kev nyab xeeb, thaum Channel 70 yog siv rau Digital Selective Calling (DSC) kev ceeb toom ntxhov siab. Ua raws li * Cov Kev Cai Txheej Txheem rau Txoj Cai Kev Tshawb Fawb Hauv Tebchaws ntawm Hiav Txwv Navigation -going Ships (2020)*, lub zog xa hluav taws xob ntawm VHF cov cuab yeej yuav tsum nruj me ntsis txwv rau thaj tsam ntawm 6 txog 25 watts.
Medium/High Frequency (MF/HF) Cov Khoom Siv: Siv rau nruab nrab - mus rau -ntev -nkoj ntau yam - mus rau - kev sib txuas lus ntawm ntug dej. Nws yog nruab nrog DSC davhlau ya nyob twg thiab nqaim -Band Direct-Printing (NBDP) cov cuab yeej; saib-ua kom muaj ntau zaus suav nrog kev sib txuas lus thoob ntiaj teb xws li 2182 kHz (MF) thiab 4125 kHz (HF).
Satellite Communication Terminals: INMARSAT-SES muab kev pabcuam thoob ntiaj teb rau xov tooj, xa cov ntaub ntawv, thiab ceeb toom kev ntxhov siab. Cov terminals no yuav tsum tau siv hluav taws xob los ntawm lub vaj huam sib luag tshwj xeeb thiab txuas nrog lub zog hluav taws xob thaum muaj xwm txheej ceev.
