This　paper　investigates　the　decoding　performance　of　channel-coded　ship-based　satellite　communications　on-the-move　(SSCOTM)　between　ships　and　satellites.　In　practical　communications,　ship　antennas　deviated　from　satellites　by　wind　waves　suffer　rapid　channel　degradation　with　serious　burst　errors　and　even　losing　all　the　data.　To　address　this　issue,　we　first　establish　a　mathematical　model　to　study　the　influence　of　wind　waves　and　derive　the　effective　signal-to-noise　ratio　(SNR)　in　SSCOTM.　Second,　we　propose　a　vertical　Reed-Solomon　(RS)　with　cyclic　redundancy　check　(CRC)　and　low-density　parity　check　(VRC-LDPC)　code,　where　the　RS　code　and　LDPC　code　are　treated　as　the　inner　code　and　outer　code　to　correct　both　burst　and　random　errors,　respectively.　Moreover,　both　the　encoder　and　the　decoder　of　the　proposed　VRC-LDPC　can　be　carried　out　in　parallel　implementations.　Finally,　simulation　results　show　that　the　proposed　VRC-LDPC　performs　much　better　than　the　conventional　codes　of　the　Consultative　Committee　for　Space　Data　Systems　(CCSDS)　standard.　Thus,　this　paper　provides　an　excellent　alternative　channel　code　for　reliable　error-correction　systems　of　SSCOTM.　©　2013　IEEE.
