Abstract

The Laser Communications Relay Demonstration (LCRD) mission is the first NASA end-to-end optical relay. The project has been operating since the Space Test Program Satellite-6 (STPSat-6) spacecraft launch in December, 2021. The aim of this project is to show the feasibility of optical communications as a high-bandwidth service provider for NASA from geo-synchronous orbit to ground. This capability has been demonstrated through a long-term study of performance over time and varying channel conditions. Optical Ground Station 1 (OGS-1), located at Table Mountain Facility near Wrightwood, CA, has supported first-light and commissioning, and the current experiment phase, covering the recent three-year period on a largely daily operational cadence. Configured links include relays with Optical Ground Station 2 (OGS-2) in Haleakalā, Hawaii and ground-to-satellite loopbacks. This paper discusses the considerations behind OGS-1 data management and its development over the course of operations. An experimental scenario is described wherein this embedded system is demonstrated.

用于激光通信中继演示的日用光通信地面站数据管理与数据产品

激光通信中继演示（LCRD）任务是NASA首个端到端光学中继。该项目自2021年12月发射空间测试计划卫星-6 （STPSat-6）航天器以来一直在运行。该项目的目的是展示光通信作为NASA从地球同步轨道到地面的高带宽服务提供商的可行性。这种能力已经通过长期的性能研究和不同的信道条件得到了证明。光学地面站1 （OGS-1）位于加利福尼亚州赖特伍德附近的桌山设施，支持首次照明和调试，以及目前的实验阶段，覆盖了最近三年的大部分日常操作节奏。配置的链路包括与位于夏威夷haleakalha的2号光地面站（OGS-2）的中继和地对星环路。本文讨论了OGS-1数据管理及其在操作过程中的开发背后的考虑因素。描述了一个实验场景，其中演示了该嵌入式系统。
