Abstract :
This paper includes development of a distributed data processing system for both space mission vehicles and test results by ground experiment. We developed test models of OBC (On-Board Computer), RIU (Remote Interface Unit), and MIL-STD-1553B data bus to meet requirements of a space vehicle. OBC and RIU hardware specifications, memory size, number of channels, data acquisition frequency and CPU throughput are designed followed by quantitative analysis considering its mission requirements. Tests of the developed systems were conducted with a satellite attitude control simulator to demonstrate their applicability on space mission vehicles. Experimental results show the developed system can be applied to space mission vehicles through further enhancement of performance in the future
