内容总结:
总部位于华盛顿州贝尔维尤的Xplore公司在首颗卫星发射九个月后,首次公布了其从太空轨道拍摄的朝鲜领土高光谱影像。该影像由XCUBE-1卫星通过可见光与近红外波段采集,于今日在西雅图飞行博物馆举办的"太空优势峰会"上正式发布。
公司联合首席运营官丽莎·里奇表示,图像清晰显示了"疑似水稻田的半淹没农田",同时识别出水产养殖场与盐田地貌。她强调:"此次影像发布具有重大突破意义"。该卫星于去年12月通过SpaceX的"Bandwagon-2"共享载荷任务进入低地球轨道,自今年6月起开始传回观测数据。
XCUBE-1卫星影像分辨率达5米/像素,通过假彩色成像技术强化地貌特征差异(如红色调标识植被)。重复过境拍摄可追踪新建设施与地表变化,为情报分析提供重要参考。2023年,Xplore等六家企业与美国国家侦察局签署了为期五年的高光谱数据供应合同。
此次合作隶属于NRO推进高光谱成像应用的多阶段计划:第一阶段聚焦系统能力评估与网络安全规划,第二阶段重点考核在轨性能与数据产品采购。除国防安全应用外,成立于2017年的Xplore公司正基于"太空即服务"商业模式,同步开展商业遥感卫星及轨道平台研发业务。

总部位于华盛顿州贝尔维尤的Xplore公司在发射首颗卫星九个月后,首次公开了从太空轨道拍摄的朝鲜领土高光谱影像。
这张由XCUBE-1卫星在可见光与近红外波段拍摄的影像,今日于飞行博物馆举办的西雅图太空优势峰会上亮相。Xplore联合创始人兼首席运营官丽莎·里奇表示,影像中可见"可能为稻田的半淹没农田",以及水产养殖场和盐田。"这对我们而言是重大突破,"里奇强调。
该卫星于去年12月通过SpaceX的"Bandwagon-2"共享发射任务进入近地轨道,并于今年6月开始传回遥感影像。XCUBE-1的影像分辨率达每像素5米(16英尺),通常采用假色成像技术强化地貌特征差异——例如用红色调标示植被。"观测结果远超预期,"里奇透露。
通过多次飞越观测,此类影像可追踪新建设施或地表特征变化,为情报机构提供重要研判依据。Xplore是2023年与美国国家侦察局签订五年期高光谱数据供应合同的六家企业之一。
此项合作隶属于NRO推进高光谱影像应用的多阶段计划:第一阶段聚焦系统能力评估,包括单传感器与星座层级性能分析,以及商业与网络安全规划;第二阶段着重在轨能力验证及数据产品采购。
除国家安全领域外,Xplore正将其"太空即服务"商业模式拓展至商业遥感领域。这家成立于2017年的企业目前同步开展卫星及轨道平台研发业务。

Nine months after the launch of its first satellite, Bellevue, Wash.-based Xplore is sharing a hyperspectral view of North Korean territory as seen from orbit.
The image, captured in visible and near-infrared wavelengths by Xplore’s XCUBE-1 satellite, was unveiled today at the Seattle Space Superiority Summit at the Museum of Flight. Xplore’s co-founder and chief operating officer, Lisa Rich, said the picture shows “semi-submerged farms that are likely rice paddies,” plus fish farms and salt flats.
“This is a big reveal for us today,” Rich said.
XCUBE-1 was sent into low Earth orbit last December as part of SpaceX’s Bandwagon-2 satellite rideshare mission. Xplore began sharing imagery from the satellite in June.
XCUBE-1’s images have a resolution of 5 meters (16 feet) per pixel, and are typically shown in false colors to accentuate differences in terrain. For example, shades of red are used to indicate vegetation. “We’re seeing more than we expected to see,” Rich said.
Over the course of repeated flyovers, such images can track the construction of new facilities or other changes in surface features. That can provide valuable insights for intelligence agencies.
Xplore is one of six companies providing hyperspectral satellite data to the National Reconnaissance Office under the terms of five-year contracts awarded in 2023.
The contracts are part of NRO’s multi-stage effort to learn more about the utility of hyperspectral imagery. The first stage focuses on analytical studies to provide estimates of system capabilities at both the individual sensor and constellation levels, as well as business and cybersecurity planning. The second stage focuses on assessing on-orbit capabilities and procuring data products.
Providing data for national security purposes is just one of the applications that Xplore is targeting for its “Space as a Service” business model. The company, which was founded in 2017, is also developing satellites and orbital platforms for commercial remote sensing.
