IKONOS卫星又称“伊科诺斯卫星”（Ikonos），是一颗商业对地观测卫星，并且是世界上第一颗分辨率优于1m的商业遥感卫星，可提供多光谱（MS）和全色（PAN）图像。IKONOS卫星的发射被称为“空间时代历史上最重要的发展之一”。IKONOS卫星的名词来源于希腊词eikōn，意为图 …

IKONOS-2 was built in parallel with and as a nearly identical twin to IKONOS-1. Whereas IKONOS-1 was built with Ring Laser Gyros (RLGs) for attitude rate sensors, IKONOS-2 fortuitously was built with Hemispherical Resonator Gyros (HRGs). RLGs were found to be incompatible with long-duration space missions, whereas HRGs could last 10 or more ...

2024年12月24日 · Ikonos-2 was decommissioned in March 2015, ending a 15-year mission life. <p>Launched by Space Imaging in 1999, Ikonos-2 was the world’s first commercial high-resolution imaging satellite. Ikonos-2 was built in parallel with and as an identical twin to Ikonos-1, however failure to launch Ikonos-1 led to the renaming of Ikonos-2 to Ikonos ...

IKONOS-2 was a three-axis stabilised spacecraft, using the LM900 satellite bus system (also referred to as Block-1). The LM900 spacecraft design was based on the CRSS imaging bus. The attitude was measured by two star trackers and a Sun sensor and controlled by four reaction wheels (actuators); location knowledge was provided by a GPS receiver.

1999年9月24日，ikonos-2卫星由雅典娜2号运载火箭在 范登堡空军基地 发射成功，成为世界上首颗分辨率优于1m的商业 遥感卫星 。[3]2015年3月31日，ikonos卫星在超额服务15年后退役，其工作时间是设计寿命的2倍多。

2023年12月6日 · IKONOS-2 Metadata Updated: December 6, 2023. Since its launch in September 1999, GeoEye's IKONOS satellite has provided a reliable stream of image data since January 2000, which has become the standard for commercial high-resolution satellite data products. With an altitude of 681 km and a revisit time of …

2020年4月10日 · 现在轨运行的艾科诺斯－2(ikonos－2)卫星为太空成像公司拥有，是1999年9月24日由洛马公司的雅典娜－2运载火箭从范登堡空军基地发射的。 在此之前，雅典娜－2火箭曾在同年4月27日发射了艾科诺斯－1卫星，但因火箭整流罩分离问题致使卫星未能入轨。
