Integrated Control and Data System

The Integrated Control and Data System is the ideal framework for developing & verifying new satellite technologies. It represents the technological core of BayernSat, and includes the whole electronic system and the corresponding software for operating the satellite and the telepresence mission. BayernSat's ICDE offers technological innovation in the following areas:
high-performance processors
COTS components
redundancy strategies
reliability

ICDE

The ICDE is composed of a technological part and standard functionalities, which are necessary for satellite operation. The ICDE is a multidisciplinary cooperation of Bavarian companies and universities. The high-performance processor unit is composed of a power PC standard processor and a processing array (XPP). Both components have been developed as COTS for commercial use, but can easily be converted for space applications with relatively simple measures. The standard components were already developed for other space projects; they merely have to be reassembled specifically for BayernSat.

Software

Software Packages are required for the operation of BayernSat on the satellite as well as on the ground.

The ground software has to provide the well-known functionalities of commanding and monitoring the satellite. As the BayernSat cameras are to be steered from the ground by "randomly selected" users, the software (on the satellite and on the ground) has to allow adequate access to the satellite during this "telepresence stage". The overall system software and hardware has to facilitate the transmission of a steering command of the satellite within a second, and the reproduction of the new images of the camera on the ground.

A cooperation project with the University of Applied Sciences Hof was set up for the development and adaptation of these software packages. On the other hand, we are currently negotiating a possible cooperation with Astrium for the development of the OnBoard software to be able to use larger finished and qualified software modules within the BayernSat project.

As neither the Institute of Astronautics nor the University of Applied Sciences Hof have the required experience, and also as there is some time pressure, it was decided to use the commercially available software "Framtec" of the company CAM for the command and control software in the control centre of BayernSat at the LRT . Another advantage of the software is that it can also be used to steer the antennas at the LRT.
