CR1- Observation range requirements | Surface design. Surface design determines reflective range. |
CR2- Monitoring surface shape requirements | Continuous monitoring and feedback on the real-time deformation accuracy, dynamic stability and environmental adaptability of the active reflective surfaces. |
CR3- User interface and remote access requirements | Submission of observation proposals, access to data and remote control of equipment |
CR4- Communication requirements | Receive and give instructions |
CR5- Dynamic response capability requirements | Real-time monitoring of reflective surface deformation, feedback data through the sensor network, dynamic error correction. |
FR1- Reflective range function | Derived from user requirements CR1 |
FR2- Monitoring surface shape function | Derived from user requirements CR2 |
FR3- User Interface and Remote Access Function | Derived from user requirements CR3 |
