Abstract
Satellite constellations will soon play a fundamental role in global broadband and heterogeneous communication architectures. These constellations will offer ubiquitous access to interactive multimedia services. Spatial embedded systems must evolve accordingly to provide a robust real time support, including a dynamically extensible runtime environment. In other words, these systems must allow new services or features to be dynamically loaded and linked to the embedded software. Object technology answers the need for dynamically extensible systems. But can it also answer the constraints of embedded real-time systems? First experiments with Java indicate that an efficient real time scheduling of Java tasks can be implemented on top of a real-time kernel. The paper also brings solutions for an efficient and robust memory management Thus, the paper shows that it is realistic, proficient and cost effective to use object technology for designing the new generation of real-time embedded systems.
