AI Technical Summary
Ships are affected by environmental disturbances such as waves and wind during navigation, which causes changes in antenna attitude and affects the strength of communication signals. Existing stabilization platforms or mechanical servo systems are costly, slow to respond, and complex to maintain, making it difficult to achieve real-time compensation and link optimization.
The ship's multi-attitude angle data are acquired by a nine-axis inertial measurement unit, a Cartesian coordinate system is established, the spatial transformation of the antenna position is calculated, and the antenna direction is determined by vector operation by combining the initial antenna orientation and the transformed antenna position. The antenna gain is matched and the signal strength change is predicted.
It achieves end-to-end prediction of signal strength changes from ship motion, accurately captures the impact of ship attitude changes under wave fluctuations on the signal, provides a reliable prediction basis for stable communication quality, and avoids prediction deviations.
