2012年5月29日 · ETS-VIII is an advanced JAXA (Japan Aerospace Exploration Agency) technology demonstration satellite with the aim to develop and verify the world's largest geostationary satellite-bus technology, considered to be necessary for space missions at the beginning of the 21st century.

JAXA Engineering Test Satellite ETS-VIII (Kiku 8) was the eighth technology test satellite in a series which started with ETS-1 in 1975 by NASDA. It was launched with the H-2A on December 18, 2006. ETS-VIII was developed by JAXA in cooperation with NICT and NTT. The aim of ETS-VIII was to enable satellite communications with small

2012年10月25日 · JAXA started a data transmission test from a GPS tsunami gauge through the Engineering Test Satellite-VIII KIKU No.8 (ETS-VIII) on Oct. 24 in cooperation with the National Institute of Information and Communications Technology (NICT), Hitachi Zosen Corporation, the Earthquake Research Institute of The University of Tokyo, and Kochi national ...

Major features of the ETS-VIII demonstration include a light body structure to improve the payload to bus system ratio to 40%, an increase in bus power supply voltage to 100 V, and use of CCSDS-compliant packet transmission and MIL-STD-1553B data bus.

其中最近发射的一颗就是工程试验卫星ets viii(kiku no.8)，它也是世界上最大的 地球同步卫星 之一。ets viii将进行大型可展开反射器(s频段)的轨道实验。 ETS VIII将进行大型可展开反射器(S频段)的轨道实验。

The purpose of Engineering Test Satellite-8 (ETS-8/ETS-VIII) is to support development, experimentation and confirmation of large satellite bus technology, large-scale deployable antenna technology, mobile satellite communications system technology, mobile satellite digital multimedia broadcasting system technology and basic positioning ...

2022年1月21日 · 空间可展开天线 是工作在太空环境下的具有展开功能的天线，是航天器无线通信系统中不可或缺的重要装备，同时也是国际宇航界研究的前沿与热点，广泛应用于星际探测、卫星导航、移动通信、电子侦察和射电天文等领域。 在我国“十四五”规划和 2035 年远景目标纲要中，规划的空间基础设施体系建设、星际探测、探月工程四期、北斗产业化等重大航天工程均对空间可展开天线提出了迫切的需求，开展可展开天线相关理论及应用研究具有较为重要的科研价值 …

2019年7月24日 · 其中最近发射的一颗就是工程试验卫星ETSVIII (KIKUNo.8)，它也是世界上最大的地球同步卫星之一。 ETSVIII将进行大型可展开反射器 (S频段)的轨道实验。 这颗卫星装备两架可展开天线，是世界上最大的可展开天线之一。 ETSVIII将进行大型可展开反射器 (S频段)的轨道实验。 装备两块太阳能电池板，能够产生7.5千瓦的电力。 这颗卫星的全长为40米 (131英尺)。 每个可展开的网状反射器的面积是19米×17米 (62.3×55.8英尺)。 碟形反射器是由镀金的钼制成的 …

ETS-VIII (Engineering Test Satellite VIII) is an advanced JAXA (Japan Aerospace Exploration Agency) technology demonstration satellite with the aim to develop and verify the world's largest geostationary satellite-bus technology, considered to be necessary for space missions at the beginning of the 21st century.

The ETS-VIII's missions are to develop technologies, and test and verify them in space. The targeted technologies include mobile-satellite communications, mobile-satellite digital multimedia, and basic technologies for building satellite positioning systems, through large-scale geosynchronous satellite bus technologies for 3-ton class ...
