Subsequently, Edisoft has reached an agreement with OAR to implement an RTEMS maintenance centre (see related link) in Europe. Edisoft has complemented the validation and the toolset associated with RTEMS for the specific needs of the European space industry. Gaisler Research also provides services based around RTEMS on ERC32 and Leon.

RTEMS has already been used in several space applications, in particular FedSat (a scientific Research and Development microsatellite), the Surrey's Solid State Data Recorder (a component used in the Disaster Monitoring Constellation), ChipSat (a System-on-Chip architecture), the Electra UHF antenna of the Mars Reconnaissance Orbiter and in the Galileo GIOVE-A and Herschel-Planck satellites.
 
 
RTAI Linux in ExOS for Mars robots and in PISA for instruments
 
A version of RTAI Linux for Pentium 3, ExOS has been developed for a robotic application, the ExoMaDeR planetary rover prototype. As a consequence, particular attention was given to the capability of RTAI to supply a reliable hard real-time execution environment for the ExoMaDeR operations scenario. One of the focal points is the control of the motors of the rover, as they are controlled by FPGAs and need timely actuation. The work demonstrated that the prototype behaved properly and allowed a nominal robot trajectory, which was not the case with a normal Linux in overload situations.

PISA is a software framework for integrated satellite payload controllers, based on Linux. It allows the separate development of several Principal Investigator applications on Linux systems. The applications are then integrated on the flight instrument.
 
 
XLuna, a Leon-based Linux on top of RTEMS
 
Critical Software is developing XLuna, a real time version of Linux. It has adopted RTEMS as the underlying real-time scheduler, and runs on the Leon processor.
