Resumen
- More then one century ago was developed first radio and used onboard ship for communication and safety purposes. Namely, Mobile Satellite Communication (MSC) systems were conceived for the transmission and receiving of telegraphy and telephony signals via mobile antenna at first from ships, and then from cars, trains and aircraft. The consideration of antenna transmission is inevitable, especially in MSC systems, where their propagation characteristics are much affected by different and changeable local environments during movement of mobile and differ greatly from those observed in fixed satellite systems. To create adequate antenna hardware design for MSC systems, engineers have to consider all related factors in order to realize full mechanical and transmission potentials. This article describes evolution and development of mobile antenna systems, classification and types, and characteristics of MSC for Ship Earth Station (SES) and Aircraft Earth Station (AES).
