Design of VxWorks-based software architecture for space optical remote sensor

In order to satisfy requirements of real time and parallel control for the space optical remote sensor and implement the high integration of software, a kind of VxWorks-based multitask software architecture was put forward. Firstly, the technological requirements of optical remote sensor were analyzed in detail and functions and performances of the optical remote sensor were fixed. Task that was based on each function of optical remote sensor was compartmentalized. Then, software architecture of optical remote sensor was designed. Finally, experiments were carried out and results verified the accuracy and feasibility of the software architecture. Test results showed that the software architecture satisfied the requirements of real time and parallel control for the space optical remote sensor, its functions and performances met the system design target perfectly, and the software architecture was applicable to the engineering application of space instrument.
