RTOS safety ranking
- ABI Research placed QNX, Wind River, SYSGO, and Green Hills at the top of its RTOS ranking for robotics safety. - The update highlighted BlackBerry's QNX expansion with NVIDIA as a notable business development for the RTOS market. - RTOS vendor positioning influences certifiable platform choices for safety-critical robotics and avionics systems.

A real-time operating system is the software layer that decides what a robot or flight computer does first, and ABI Research’s latest safety ranking put QNX, Wind River, SYSGO, and Green Hills at the top. (abiresearch.com) ABI Research published the ranking on April 22, 2026, and said the list focused on commercial real-time operating systems for robotics functional safety. The firm cited certified architectures, mixed-criticality support, and ecosystem partnerships as the main factors separating leaders from the rest of the field. (abiresearch.com) QNX said it placed first overall with a score of 87.1 and also took ABI Research’s “Top Innovator” designation. The company tied that result to its microkernel design and its QNX OS for Safety 8.0 product line. (qnx.software) This corner of the software market matters because safety-certified operating systems are the base layer for machines that cannot miss deadlines, including industrial robots, medical systems, and avionics computers. Wind River says its VxWorks Cert Edition is built for projects that need certification evidence under DO-178C, IEC 61508, ISO 26262, and IEC 62304. (windriver.com) SYSGO and Green Hills compete on the same certification-heavy terrain. SYSGO says PikeOS 5.1.3 is pre-certified for standards including DO-178C DAL A, ISO 26262 ASIL D, EN 50716 SIL 4, and IEC 61508 SIL 3, while Green Hills says INTEGRITY-178 and INTEGRITY-178 tuMP have delivered more than 80 DO-178B/C Level A and EAL 6+ certification packages. (sysgo.com) (businesswire.com) QNX’s business momentum got a separate boost on April 20 at Hannover Messe, where BlackBerry said it was expanding its collaboration with NVIDIA. The companies said QNX OS for Safety 8.0 will be integrated with NVIDIA IGX Thor and the Halos safety stack for robotics, medical, and industrial edge systems. (accessnewswire.com) That pairing joins two pieces buyers increasingly want in one platform: deterministic control software, which means tasks run on time every time, and high-end artificial intelligence compute at the edge. QNX says OS for Safety 8.0 is certified by TÜV Rheinland to ISO 26262 ASIL D, IEC 61508 SIL 3, IEC 62304 Class C, and ISO/SAE 21434. (qnx.software) The avionics angle is not theoretical. Wind River markets VxWorks Cert Edition directly for airborne software programs under DO-178C, and Green Hills said on April 23 that NASA and Lockheed Martin’s Orion spacecraft flew with INTEGRITY-178 on its most critical systems. (windriver.com) (businesswire.com) ABI Research’s ranking does not certify any product by itself, and vendors still have to prove compliance in each program with regulators, auditors, and customers. But for robotics makers and aerospace contractors choosing a software base in 2026, the short list now looks clearer than it did a week ago. (abiresearch.com)
