任务简介

ASBM（北极卫星宽带任务）1号和2号是两颗由诺斯罗普·格鲁曼公司为挪威航天局建造的双子卫星，与Inmarsat和挪威国防部合作。它们旨在为北极地区的民用和军用用户提供移动宽带覆盖。美国空军在ASBM卫星上提供极高频扩展数据速率有效载荷，作为增强极地系统资本重组（EPS-R）计划的一部分。

↗ SpaceX ↗ Arctic Satellite Broadband Mission

ASBM (Arctic Satellite Broadband Mission) 1 & 2 are two twin satellites built by Northrop Grumman for Space Norway, in cooperation with Inmarsat and the Norwegian Ministry of Defence. They are designed to bring mobile broadband coverage in the Arctic for both civilians and military. The US Air Force provides the Extremely High Frequency eXtended Data Rate payloads on ASBM satellites as part of the Enhanced Polar System Recapitalization (EPS-R) program.
