WHAT CHALLENGES WERE BEING FACED?
A key goal was to find alternatives to the ARINC429 data bus that would offer lower cost, better performance, more flexibility, and broad applicability in aircraft and avionics systems. Cost considerations included not only non-recurring engineering but also the impact of certification, operations, and logistics. These were weighed against the key performance factors of throughput, latency, and quality of services.
WHY WAS LYNX SELECTED?
Modified for the specific requirements of aircraft applications, the Avionics Full Duplex (AFDX) switched Ethernet standard was specified by Airbus. CES developed a range of AFDX hardware modules, with the LynxOS RTOS at their core. LynxOS ensures real-time deterministic computing for flight tests and simulation. The POSIX compliance of LynxOS is helpful in simulation systems since the various contributing equipment vendors can provide specific models for the sub-systems, with the knowledge that compatibility will be assured.
WHAT IS LYNXOS?
LynxOS is a POSIX, multi-core hard real-time operating system for embedded devices in avionics, automotive, and more. LynxOS has been deployed in millions of embedded devices and has operated reliably for 30+ years across multiple safety- and security-critical embedded markets. It is a tried-and-true approach for hosting applications on a Unix-like OS model wherein all resources and application services reside.
