In view of the characteristics of multidisciplinary and cross-regional collaborative development of space optical remote sensor, the collaborative modeling and management requirements from the mission demonstration, scheme design, detailed design to the manufacturing stage are analyzed, and an architecture of space optical remote sensor multidisciplinary collaborative digital development environment is proposed, for solving the low collaboration efficiency problem. The system integration technology based on unified model is adopted to realize top-down design throughout the whole design process. By developing the unified collaborative platform, the design process knowledge is solidified to the platform. Also, the process driven collaborative design between the overall design and disciplinary design, and centralized management of various models are realized. Then, the development data transmission link is gotten through. Based on the mixed sharing mode, a safe and controllable shared collaborative development space is formed. The application shows that development environment can support the multidisciplinary and cross-regional collaborative development online and efficiently.
