Error Control Coding (ECC) is applied in satellite data communication with Automatic Repeat Request (ARQ) method. Bit error checking use the calculation of 15 bit Cyclic Redundancy Check (CRC) Controller Area Network (CAN) standard. The calculation of CRC is attached in CAN frame over IP communication protocol between primary OBC and secondary OBC. The triple modular redundant system implemented on a Linux-based operating system that installed on the on-board computer. The CAN frame over IP simulation with manual input corrects all corrupt data. When the simulation use the network emulator, the system corrects 100 % data in 0-10 % value of corrupt with maximum time transfer 84.472 seconds. ION DTN corrects all corrupt data with the value from 0 to 2 % and maximum delay at altitude 50,000 kms orbit of data using network emulator for TMTC mission. The testing results shows that the system will keep carrying out its mission as long as the fault does not occur on all three on-board computer at the same time.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Automatic repeat request,CAN frame over IP,Controller area network,Cyclic redundancy check,Data-communication,Error control coding,Onboard computers,Triple modular redundant[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]CAN frame over IP,CRC,ECC,ION-DTN,OBC[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICICI-BME.2015.7401377[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
