“…Laser short-range detection technology has been widely used in communication [1][2] , remote sensing [3][4][5] , robot positioning and mapping [6][7] and other fields. However, in the real environment, due to the complex weather, particles such as clouds, rain, smoke and dust in the atmosphere will have an impact on the LIDAR measurement [8][9] .…”

Objective During communication between the highaltitude aircraft and the underwater platform, the highaltitude aircraft moves faster and passes through the area where the underwater platform is located in a shorter time. Additionally, limitations of the receiving field of view and laser emission window of the underwater platform restrict the effective communication time, impeding the establishment of a constant optical link. The utilization of a beacon lightbased communication method extends the capture time and adds complexity to the link establishment in the underwater communication platform system. To overcome these challenges, a tracking and pointing system based on the orbit forecasting of the underwater platform is devised to establish an uplink between the underwater platform and highaltitude aircraft.Method In contrast to the acquisition, tracking, and pointing (ATP) systems employed in space laser communications, the system we developed eliminates the need for an acquisition module. Instead, the underwater platform is required to obtain the realtime position of the aircraft during communication to achieve precise pointing of the aircraft. Several theoretical algorithms for orbit forecasting are assessed, and the Runge -Kutta method is selected for its computational efficiency. The laser pointing system structure is designed for an underwater platform , and the correlation between the motor rotation angles in two directions and the aircraft coordinates is derived. Subsequently, we develop computer
