    摘要:

    针对现行移动卫星地面站采用基于激光陀螺跟踪卫星方案的价格昂贵、使用不便等不足,提出了基于梯度法跟踪卫星的方案.同时提出基于梯度法和数字波束形成GRAD-DBF(grads-digital beam forming)技术的跟踪方案.系统无需激光陀螺、机电转台-伺服系统,能跟踪多颗非静止卫星.最后对GRAD-DBF跟踪方案和算法用Mathcad软件作了计算机仿真,给出了仿真程序和仿真结果.

    Abstract:

    Existing mobile satellite communication ground stations mostly achieve satellite tracking with laser gyro.But such stations are not only expensive but also ponderous for installation in moving vehicles,and they can only track geostationary satellite.In order to solve these problems,a tracking scheme using grads tracking method is proposed.With this scheme,not only the expensive laser gyro can be eliminated from the system,but also non-geostationary satellite can be tracked.A tracking scheme based on GRAD-DBF(grads-digital beam forming)are presented.The tracking system can eliminate both the laser gyro and the mech-electronic rotating pedestal and servo system,at the same time it has the ability of tracking multiple non-geostationary satellites.Simulation programs and results of the tracking scheme are given by the software Mathcad.
