Unified Simulation Test Facility for Aerospace Vehicles
Aerospace vehicle carries On-Board Control & Guidance (OBCG) software (s/w) resident on On-Board Mission Computer (OBMC). This OBCG s/w is validated on various simulation test-beds for various mission critical errors. Non Real Time Simulation (NRTS) test-bed is used to validate the s/w for implementation, functionality and performance. Robustness of Controller design is validated through Monte-Carlo Simulation (MCS). Hardware-In-Loop-Simulation (HILS) test-bed is used to validate OBCG s/w for functionality & performance in the presence of Real Time (RT) issues like communication delays, system lag, scheduling, interfacing, execution times & Hardware subsystems problems. Here, in this publication, a new concept of ‘Unified Simulation Test Facility for Aerospace Vehicles (USTFASV)’ is brought out, which facilitates Model Driven On-board Controller S/w Development (MDOBCSD), Non Real Time Simulation, Monte-Carlo Simulation with Test Automation (MCSTA), Real Time Full Simulation and Real Time Hardware-In-Loop-Simulation. This Test Facility unifies all the simulations on single platform.
