摘    要: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.
