Hybrid tracking method and apparatus consisting of step tracking and mono-pulse tracking for improve performance in tracking satellite in mobile satellite communication terminal

摘要

According to an embodiment of the present invention, a mixed tracking method of step tracking and monopulse tracking for improving satellite tracking performance of a mobile satellite communication terminal may include: performing a search mode when a beacon signal is below a threshold; And a tracking mode performing a tracking mode if the level of the beacon signal is higher than the threshold value. The performing of the searching mode includes raster scanning when the level of the beacon signal is less than or equal to a tracking level. Scan), and if the level of the beacon signal is higher than the tracking level, the tracking mode is performed, and satellite tracking can be performed in a wide area, and high-speed and high-precision satellite tracking performance can be secured.
