This is because its low power consumption and real-time performance are valued in the field. For example, the RTOS has been installed in the asteroid explorer, \u201cHayabusa, (MUSES-C),\u201d its exploration robot, \u201cMinerva,\u201d the Hayabusa\u2019s successor, \u201cHayabusa2,\u201d the spectroscopic planet observatory satellite, \u201cHisaki (SPRINT-A),\u201d and the satellite launch rocket, \u201cEpsilon.\u201d<\/p>\n\n\n\n<p>Furthermore, the next generation of highly reliable RTOS, \u201cT-Kernel 2.0 AeroSpace (T2AS)\u201d was developed bye YRP Ubiquitous Networking Laboratory (YRP UNL) in collaboration with the Japan Aerospace Exploration Agency (JAXA) and it was announced in 2013. T2AS is based on T-Kernel 2.0 which was developed by TRON Project. Due to this, T2AS can utilize many existing TRON software resources.<\/p>\n\n\n\n<p>T2AS incorporates the following three major functions for the aerospace field:<\/p>\n\n\n\n<ul><li>memory protection<strong>&nbsp;<\/strong>that&nbsp;does not affect the processing speed<\/li><li>high-precision time management with physical timer<\/li><li>deletable OS functions to reduce memory usage and to improve operational security<\/li><\/ul>\n\n\n\n<p>T2AS has been installed in the satellite, <strong><a rel=\"noreferrer noopener\" aria-label=\"\u201cArase (ERG*),\u201d (opens in a new tab)\" href=\"https:\/\/www.isas.jaxa.jp\/en\/missions\/spacecraft\/current\/erg.html\" target=\"_blank\">\u201cArase (ERG*),\u201d<\/a><\/strong> by JAXA, and is expected to be used in other fields such as transportation, medical electronics and factory automation. <br><span style=\"font-size:12px;\">* ERG (Exploration of energization and Radiation in Geospace)<\/span><\/p>\n\n\n\n<p>We created the &#8220;T2AS Highly Reliable Application Handbook&#8221; to explain the verification process and development guidelines to ensure the reliability of the application that uses T2AS.
