Separation kernels are becoming more important for real-time sensor processing in uncrewed systems. Nick Flaherty explains how they work. Real-time operating system (RTOS) implementations are changing as uncrewed system platforms evolve. The technology is used widely, from small operating systems for UAVs to larger and more complex implementations running critical systems in driverless cars.

Hybrid system-on-chips increasingly integrate heterogeneous processors. However, developers see them as one component that they want to develop as integrated as possible. A homogeneous RTOS and hypervisor ecosystem for both MPU- and MMU-supported processors provides the critical convenience gain.

When developing embedded systems that are to be real-time capable, one of the first and most important questions is whether the applications should run under a real-time operating system (RTOS) or whether a bare-metal solution should be developed. Bare-metal programming is generally understood to mean that an application is written directly on the hardware without using an external programming interface, i.e. an operating system. Applications access here directly hardware registers of…

Development of certifiable systems and software for European Space Applications requires strict adherence to the ECSS standards. ECSS - the European Cooperation for Space Standardization - is a cooperation of the European Space Agency (ESA), national space agencies and the European Industry Association Eurospace with the aim of developing and maintaining coherent, commercially oriented and user-friendly standards for space applications. The main intention is to improve the performance and…

When people think of satellite-based GPS, they envision a high-tech satellite navigation system that can pinpoint locations worldwide to within a few meters. But global navigation systems (GNSS) such as the American GPS or the European Galileo struggle with many environmental interferences. So-called satellite-based augmentation systems (SBAS) improve the performance of these navigation systems by correcting their data. From 2022, the Korean peninsula will also benefit from the PikeOS-based SBAS…

In many applications in the railways, aircraft or automotive industry the interaction between safety and security is of particular importance, since there are many dependencies between them and they can therefore no longer be considered separately.
