In this paper the development and implementation of a Telecommand (TC) receiver application for microsatellite communication is presented. The TC receiver application is executed and operated by a highly integrated Generic Software-Defined Radio (GSDR) platform. This platform architecture is designed for the reliable operation of multiple radio frequency applications on spacecraft. For the development and implementation process of the TC receiver application, a new model-based development workflow by Matlab/Simulink is used and evaluated.
