Abstract: |
A coordinate computing model of A-E-C three-axis stabilized antenna for ship-borne satellite station is built by using the information provided by marine inertial navigation system. Based on this model,the heel angle and the trim angel calculation formulas are derived,as well as the polarization angle adjustment formulas in maritime dynamic conditions. After simulation and analysis in MATLAB and application in practical systems,this model proves to be able to enhance the performance of the ship-borne satellite station antenna. Furthermore,this model provides the numeric analysis approach for optimization of the ship-borne satellite station antenna control algorithm. |
