任务简介

Tranche 1 Transport Layer C 是美国太空军太空发展局（SDA）为“扩散性作战人员太空架构”（PWSA）Tranche 1 传输层星座执行的六次任务之一，该星座将从低地球轨道卫星为全球各类作战人员平台提供可靠、低延迟的军事数据和连接。该星座将通过光学星间链路（OISL）互联，其性能相比现有射频交叉链路显著提升。预计将在 Ka 波段运行，具备立体覆盖能力，并采用动态组网以实现更简单的切换、更大的带宽和容错能力。本次发射搭载了由洛克希德·马丁公司制造的 21 颗卫星。

Tranche 1 Transport Layer C is one of six missions by the United States Space Force Space Development Agency (SDA) for the Proliferated Warfighter Space Architecture (PWSA) Tranche 1 Transport Layer constellation, which will provide assured, resilient, low-latency military data and connectivity worldwide to the full range of warfighter platforms from Low Earth Orbit satellites. The constellation will be interconnected with Optical Inter-Satellite Links (OISLs) which have significantly increased performance over existing radio frequency crosslinks. It is expected to operate over Ka band, have stereo coverage and be dynamically networked for simpler hand-offs, greater bandwidth and fault tolerance. This launch carries 21 satellites manufactured by Lockheed Martin.
