Design, development, and implementation of a cFS, RTEMS, and LEON3 platform

Abstract

As interest in space missions and the services they provide grows, the need to design, develop, and implement new platforms that can support the necessities of these services becomes more evident. To this end, the implementation of one of the most used software architectures in space missions, the core Flight System (NASA), to work in the Real Time Operative System RTEMS and the 32-bit LEON3/SPARC V8 processor. In order to test this platform, some applications which prove the main functionalities of the cFS software framework have been developed such as communication between components through a publish subscribe pattern, events, and data storage. These applications have been characterized and modeled using the AADL language, thus allowing the creation by a non-specialized user, through auto-code, of new custom applications.
