Need to add new core
Observation front-end for beacon loss and regain
For the civilian laser communication prototype, light point feedback and pointing control are used as the observation route, and the effective point status and recovery time are planned to be output. The page is for project evaluation and does not mean that the development has been completed or has been accepted on site.

Current capabilities and capabilities to be supplemented
Need to add new core
Need to add core computing
Light point extraction can only be used as an observation front-end, and core capabilities such as three-dimensional reconstruction, closed-loop control, wavefront or physical quantity inversion need to be developed and verified separately.
Gaps in this scenario:New system identification, controller, delay budget and lock loss processing need to be added; the existing module only provides position observation. The search state machine and control core need to be added. Point observation only supports the acquisition/tracking front end, and the data link needs to be implemented independently.
Route-level gaps:New system identification, controller, delay budget and lock loss processing need to be added; the existing module only provides position observation
"New cores required" only describes the relative development volume and does not constitute a commitment to accuracy, tempo, stability or delivery time.
