Nucleus Selected for the CNX80

Developers at Garmin began evaluating embedded operating systems for their navigation application. They needed a reliable and tested OS, provided with full source and with a flexible business model. Nucleus RTOS was chosen for the CNX80.

In addition to these requirements, Garmin developers were looking for an OS that they could certify through the FAA to meet the airborne software requirements from DO-178B for Level B software. Certification requires adequate documentation that every decision point in the source code is fully tested to ensure safe operation of an aircraft. Developers tested the Nucleus RTOS kernel and received FAA certification with no changes required.
