Abstract

A preliminary design and implementation of a Telemetry and Telecommand (T&Tc) subsystem is presented by using Commercial Off The Shelf (COTS) modules. Telemetry data are collected, stored, and then transmitted to the Ground Station (GS). Commands are executed in both autonomous and GS controlling modes. Commands are executed on the On Board Computer (OBC) according to prepared scheduled commands and patch files. Updated patch files can be loaded from the Ground Control Center (GCC) to the OBC.
