RTOS for NASA Dream Chaser cargo spacecraft will be sourced from DDC-I
NewsJune 19, 2020
PHOENIX, Ariz. Mission-critical software provider DDC-I has been chosen to provide its Deos safety-critical real-time operating system (RTOS) for use in a communications subsystem destined for the Dream Chaser Cargo System, which Sierra Nevada Corporation (SNC) is building for NASA.
The DDC-I subsystem will provide on-board communication signal processing capabilities for the Dream Chaser, which is a cargo transportation spacecraft being developed by SNC under the NASA Commercial Resupply Services (CRS2) program.
Greg Rose, vice president of marketing and product management at DDC-I, said of the selection: "We are excited to have been selected by MDA to provide the safety-critical RTOS platform for this prestigious project. Deos has a proven pedigree in the avionics industry, and our DO-178C processes track well with NASA and ESA assurance requirements. Add to that a modular, reusable architecture that decouples I/O device drivers from the RTOS and BSP and you have a tailor-made platform for rapid development, certification, and deployment of the most demanding safety- and mission-critical applications.”
The spacecraft is scheduled for at least six cargo delivery missions to and from the International Space Station between 2020 and 2024.
