Abstract
For the accomplishment of satellite's own missions, complicated control procedures and commands are required. Although absolute-Time Command and Command Sequences have been applied for controlling satellite and its operation historically, these command system only has a capability to manage sequential control process and has a limitation that cannot deal with decision and branch for corresponding to the condition of the time. To resolve above limitation, KARI has designed RTCSC which is mainly based on the existing RTCS but adopts a one-byte Op Code for supporting decision making and conditional branch. This paper introduces the design and implementation of RTCSC as On-Board Control System like OBCP, VML and IP.
