On Board Data Handling System (ODHS)
The responsibilities of the ODHS subsystem are simply, the tasks pertaining to design and manufacture of the entire hardware architecture of the on board computer. This design process is complemented to the various umbrella activities, like selection of components which fit in the power budget, interfacing requirement analysis and other space related constraints. A responsive system has to be developed which helps the satellite to perform autonomous decision making in real time. Therefore, work is also carried out, in developing a Real Time Operating System for the satellites on board controller. The team is also responsible to optimize the complex control and dynamics algorithms which is used to keep check on the satellite’s position and orientation. This team is responsible for the congregation of all sensors, actuators, memory ICs, controllers and all other hardware devices of every other subsystem.
