目前,美国正研制第5代电子侦察卫星“入侵者”(Intruder)。这种大卫星是美国“集成化”过顶信号侦察体系(IOSA)的组成部分,是利用天基网的发展思路和新的设计理念研制的,目的是提高电子侦察质量,降低系统成本。它具有多轨道能力,可代替当今静止轨道和大椭圆轨道的卫星,并集通信 At present, the United States is developing the fifth generation of electronic reconnaissance satellite “Intruder.” This satellite is part of the United States “Integrated” Overhead Signal Reconnaissance System (IOSA). It was developed using the development ideas and new design concepts of the World Wide Web. Its purpose is to improve the quality of electronic surveillance and reduce the system cost. It has multi-orbital capabilities to replace today’s geostationary orbitals and large-elliptical orbit satellites and to integrate communications
