Defence PSU Hindustan Aeronautics Limited (HAL), on Wednesday claimed to have successfully completed the first flight of Hawk-i with indigenous Real Time Operating System (RTOS) developed by it.
“It is the first indigenous RTOS in the country to be built from scratch. It is also the first instance that an indigenous RTOS has been certified by Cemilac,” HAL CMD T Suvarna Raju, said.
Cemilac (Center for Military Airworthiness and Certification) is India’s defence certifying agency for aircraft—manned and unmanned—its components and equipment.
The RTOS is the system software which provides a standard run-time environment for real-time applications execution in a safe and reliable manner.
Advanced modules like network stack and file system have been co-developed with IIT- Kharagpur which also carried out formal method based verification of the RTOS kernel.
Currently, avionics systems in India are developed using commercial RTOS procured from foreign suppliers. The import of technology leads to high cost, provides very limited flexibility in incorporating new features and adaptation to new hardware platforms.
“The imported RTOS may also be vulnerable to cyber-attacks which may compromise the safety and security of the avionics system. To overcome this dependency and achieve self-reliance, HAL had taken up the onus of designing an indigenous RTOS for safety-critical and mission-critical avionics systems,” an HAL statement issued here read.
The HAL-RTOS’ key features include address, space and time partitioning, priority pre-emptive process scheduling and health monitoring.
“The RTOS performance has been validated and the complete Operational Flight Programme, which includes real-time sensor data processing, navigation algorithm computations, controls and display management and interface management was ported and the RTOS was able to meet all its design requirements during the flight,” the statement read.
With this development, the HAL-RTOS can be made as a standard Real Time Operating System for any future avionics systems development in the country.
