本文描述了新近开发的RDI SatcomⅡ三轴天线系统的一些设计特性、它应用了一个有源天线。 前 言 RDI的Satcom和大多数其他制造厂商都利用陀螺稳定天线,这对俯仰和滚动都很小的大型船只是非常适宜的、然而,较小型船只以及具有超出陀螺控制稳定平台可能的俯仰和滚动调整范围潜势的大型船只,也是需要稳定的。 This article describes some of the design features of the newly developed RDI Satcom II triaxial antenna system using an active antenna. Preface RDI’s Satcom and most other manufacturers are using gyro-stabilized antennas, which are ideal for large vessels that are both very low in pitch and roll, however smaller vessels and with the possibility of pitch and roll adjustments beyond a gyro-controlled stable platform Large-scale vessels of potential range also need to be stable.
