The Hindustan Aeronautics Limited has developed the first flight of Hawk-i with indigenous Real Time Operating System (RTOS).
- Hawk-I is the first indigenous RTOS developed in India from scratch and certified by Bangalore based Center for Military Airworthiness and Certification (CEMILAC).
- Similac (Center for Military Airworthiness and Certification) is India's defence certifying agency for aircraft—manned and unmanned—its components and equipment.
- It is a part of the government-run Defence Research and Development Organisation (DRDO).
Highlights
- The RTOS is the system software which provides a standard run-time environment for real-time applications execution in a safe and reliable manner.
- Avionics systems in India are currently developed using commercial RTOS procured from foreign suppliers.
- The RTOS is a key technology for concurrent execution of multiple applications.
- It is beneficial in the optimal use of hardware resources which is important for the increased complexity of modern avionics software.
- Importing this new technology is very costly and it provides ery limited flexibility in incorporating new features and adaptation to new hardware platforms.
- The RTOS imported are also vulnerable to cyber-attacks which may compromise the safety and security of the avionics system.
- In order to overcome this dependency and achieve self-reliance, the HAL had taken up the responsibility of designing an indigenous RTOS for safety-critical and mission-critical avionics systems.
- Its key features include address, space and time partitioning, priority pre-emptive process scheduling and health monitoring.
- The advanced features like the network stack and file system have been co-developed with IIT- Kharagpur.
- IIT- Kharagpur also carried out formal method based verification of the RTOS kernel.
