Overview

The TTC (or TT&C) is the communication module of the CubeSats from SpaceLab. It is responsible to make the communication between the earth (a ground station) and a satellite, and is divided in two sub-modules: Beacon and telemetry.

The beacon is a independent sub-module who transmits a periodic signal containing an identification data (ID) of the satellite and some basic telemetry data. The telemetry sub-module is the main communication device. It has a bidirectional data link to receive telecommands from the earth and transmit all the requested data. The telemetry sub-module is controlled by an external device (as example, an OBDH module).
