Operating system

JetOS RTOS Developer GosNIIAS Institute for System Programming Written in C OS family Unix-like real-time operating system Working state Current Marketing target Embedded systems Available in English Russian Supported platforms PowerPC x86 ARM

The **JetOS RTOS** ([Russian](/source/Russian_language): ОСРВ JetOS) is a [Unix-like](/source/Unix-like) [real-time operating system](/source/Real-time_operating_system) under development by the [Russian](/source/Russia) [State Scientific Research Institute of Aviation Systems](/source/State_Scientific_Research_Institute_of_Aviation_Systems) and the [Institute for System Programming](/source/Institute_for_System_Programming).[1][2] JetOS is primarily designed for use in embedded systems for civil aviation, as part of the Russian strategy of [import substitution](/source/Import_substitution_industrialization).[3]

JetOS is designed to power avionics systems on commercial aircraft such as the [Yakovlev SJ-100](/source/Sukhoi_Superjet_100) and [Yakovlev MC-21](/source/Yakovlev_MC-21), enabling real-time data acquisition, processing and display for control systems, navigation and other flight parameters.[4][5] The operating systems supports running up to 30 applications to be run during flight, meeting the requirements for [DO-178C](/source/DO-178C) and [ARINC 653](/source/ARINC_653).[6]

## History

Development of JetOS began in 2016 on order of the Ministry of Industry and Trade as part of import-substitution measures to create an alternative to foreign operating systems such as [LynxOS](/source/LynxOS), [VxWorks](/source/VxWorks) and [PikeOS](/source/PikeOS).[7]

The first version of the operating system was operational in 2019, with testing and integration continuing.[8]
