Viasat入选NASA中继卫星计划第一阶段 合同最高潜在价值4.609亿美元
Carlsbad—位于美国加利福尼亚州圣迭戈县 Carlsbad 市的卫星通信公司 Viasat（纳斯达克：VSAT）11月9日宣布，公司已被美国国家航空航天局（NASA）选中参与其「用户连续性与可持续性网络扩展」计划（NEXUS）第一阶段，合同含未来阶段的最高潜在价值为4.609亿美元。
这份合同经 NASA 的 NextSTEP-3 综合广泛机构公告授出，为固定总价合同。Viasat 是第一阶段入选的三家商业公司之一，入选名单由 NASA 于11月4日定下，初期工作执行至2027年5月3日，后续选项可延续至2029年。另两家入选公司为 Astranis（最高2.643亿美元）与 Global Enterprise Solutions（最高3.404亿美元），三家合同上限合计约10.7亿美元，Viasat 一家居首。
NEXUS 是 NASA 通信服务项目（CSP）的关键组成部分。NASA 的跟踪与数据中继卫星（TDRS）舰队逐步退役后，近地任务的通信服务将转向商业公司提供。第一阶段，Viasat 国防与先进技术部门下属的空间与任务系统团队将深化一套端到端运行架构的设计与方案，为沿用 TDRS 的存量任务提供 Ka 波段中继连接，设计核心是与旧式 Ka 波段转发器兼容的小型地球同步轨道中继卫星星座，配套涵盖地面系统、卫星集成、发射管理与运行服务。
公司称，未来三年内的后续阶段将资助这套高性能、向后兼容中继服务的开发、发射与飞行演示，在 TDRS 正式退役前验证商用空间通信能力。Viasat Government 空间与任务系统副总裁 John Reeves 表示，NASA 对 NEXUS 的设想，标志着空间通信服务向商业提供方式的重大转变，该公司的卫星组网与端到端系统设计能力，可为存量与未来 NASA 任务提供有韧性的 Ka 波段中继。
Viasat 总部位于 Carlsbad，是卫星通信与组网技术公司，其业务涵盖商用宽带、政府与国防通信等领域。

Viasat Selected for Phase 1 of NASA's NEXUS Relay Initiative, With Maximum Potential Contract Value of $460.9 Million
CARLSBAD, Calif. — Viasat, Inc. (NASDAQ: VSAT), a satellite communications company based in Carlsbad, in San Diego County, California, announced on November 9 that it has been selected by NASA for Phase 1 of the agency's Network Extension for User Continuity and Sustainability (NEXUS) initiative, under a contract with a maximum potential value of $460.9 million including future phases.
The firm-fixed-price contract was awarded through NASA's NextSTEP-3 Omnibus Broad Agency Announcement. Viasat is one of three commercial awardees selected for the first phase; NASA made the selections on November 4, with initial work running through May 3, 2027, and priced options extending through 2029. The other two awardees are Astranis, with a maximum potential value of $264.3 million, and Global Enterprise Solutions, at $340.4 million, putting the combined ceiling for the three awards at about $1.07 billion, with Viasat's the largest.
NEXUS is a key effort within NASA's Communications Services Project. As the agency's Tracking and Data Relay Satellite (TDRS) fleet approaches retirement, NASA is transitioning near-Earth communications services to commercial providers. During Phase 1, Viasat's Space and Mission Systems team, within its Defense and Advanced Technologies segment, will mature the design and plans for an end-to-end operational architecture delivering Ka-band relay connectivity to legacy TDRS missions, centered on a constellation of small geosynchronous-orbit relay satellites compatible with legacy Ka-band transponders, together with ground architecture, satellite integration, launch management, and operations.
Future phases over the next three years are expected to fund the development, launch, and flight demonstration of the high-performance, backward-compatible relay service, validating commercial space communications ahead of the formal TDRS decommissioning. John Reeves, Vice President of Space and Mission Systems at Viasat Government, said NASA's vision for NEXUS reflects a significant evolution toward commercially provided space communications services, and that the company's satellite networking and end-to-end system design expertise would provide a resilient Ka-band relay capability supporting both legacy and future NASA missions.
Headquartered in Carlsbad, Viasat provides satellite communications and networking technologies across commercial broadband, government, and defense markets.
