| Abstract: | It analyzed the advantage and disadvantage of antenna structure comparing A-E two axis with A-E-C three axis in shipboard satellite communications system,and introduced the reason of ＂Secant Compensation＂ and ＂tracking blind district＂ and the solution of ＂Secant Compensation＂ in detail.By resolving the ship motion and analyzing coordinates translation,it put forward the relation of antenna structure comparing A-E two axis with A-E-C three axis and the reason why A-E-C three axis can solve ＂tracking blind district＂. |
