Internet Protocol Based Satellite On-Board System
Abstract: The reliability of
satellite data communication can be enhanced by designing two subsystems involving
data communication among subsystem and data communication between satellie and
GroundStation (GS). In this paper, Error Control Coding (ECC) is applied in
satellite data communication withAutomatic Repeat Request (ARQ) method.
Further, bit error checking uses the calculation of 15 bit CyclicRedundancy
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. OBC is designedby implementing Triple Modular Redundant system
on a Linux-based operating system. The CAN frameover IP simulation with manual
input is found to correct all corrupted data. When the simulation uses NetEM,
the system corrects 100 % data with 0-10 % value of corruption with maximum
time transfer of84.472 seconds. ION DTN is also found to correct all corrupted
data with values from 0 to 2 % andmaximum delay at an altitude of 50,000
kilometer orbit using NetEm for TMTC mission. The testing results show that the
system will keep carrying out its mission as long as a fault does not occur on
all three OBC at the same time.
