Simulation of coding layer of telecommand based on the Consultative Committee for Space Data Systems recommendation

Abstract

Telecommand is a command sent to control a remote system or systems not directly connected to the place from which the telecommand is sent. In the telecommand process, there is a data processing process so that the command data that will be sent can be read / translated and processed accurately by the satellite. The Consultative Committee for Space Data Systems (CCSDS) provides recommendations for the telecommand process. CCSDS uses layering model to describe telecommand process, one of them is coding layer. This paper will talk about the simulation of coding layer of telecommand process based on CCSDS recommendation. The simulation involves randomization process, BCH encoding, and BCH decoding using MATLAB software. The result of this simulation shows encoding and decoding process successfully managed and produced data format which complies with CCSDS recommendation.
