An improved beam tracking method for phased array in mobile satellite reception

An improved beam tracking method for phased array in mobile satellite reception is introduced. Compare to the conventional hybrid gyroscope based tracking method; the method proposed here has relative fast beam searching and tight tracking capability. With such a gyroscope free tracking method, the phased array system can be used in large acceleration and vibration environments. The prototype system can achieve less than 5 seconds in initial beam searching; the tracking procedure can work under 20~50Hz large vibration with the beam misalignment less than 1°.
