Software System Architecture

for a Space Communication System

Customer's Challenge

Our customer needed a software system architect who could quickly get up to speed on the task so that decisions could be made fast on key components. The complex communication system (physics, mechanics, optics, electronics, FPGA (Field Programmable Gate Array), software, digital signal processing) had to be considered in the software architecture.

Outcome

Solcept evaluated microcontrollers for space requirements (ECSS, European Cooperation for Space Standardization). For this purpose, the requirements for memory and computing power were first elicited. These strongly depend on the system and software architecture. Therefore, many system aspects such as interfaces, error states and handling, operating system (RTOS), algorithms and communication protocols were defined in order to evaluate the controller with low risk.
