| Abstract: | Both the blind zone and the widely employed structures of antenna pedestal in satellitic tracking during zenith pass are briefly reviewed, algorithm for program tracking of three-axis tracking system is derived theoretically. Aiming at no-blind zone tracking system by A+E+TIL structure, influence on tracking performance by mutual coupling during zenith pass is analyzed. A solution is presented, and simulation results show it could effectively improve the accuracy of tracking system. |
