The Landsat Next (LNext) document outlines the core functions and structural overview of the U.S. Geological Survey's (USGS) Mission Operations Center (MOC) for the Landsat Next program. Key functionalities include telemetry and command, orbit dynamics, planning, data processing, and archive management. The MOC oversees real-time satellite operations, scheduling activities, and managing ground network interfaces to facilitate communications and data transfers. Additionally, the document details responsibilities for analytical modeling, simulation, and configuration management, emphasizing the need for robust monitoring and trending analysis of satellite performance and health.
The operational framework consists of interrelated functions like telemetry processing, orbit maintenance, and anomaly analysis to ensure mission safety and efficiency. Emphasis is placed on automation and future-ready data management capabilities to support evolving technological demands, including machine learning applications for telemetry data analysis. By establishing clear roles and interfaces among stakeholders, the document aims to present a comprehensive architecture guiding the development, operation, and management of the Landsat Next satellite constellation, ensuring successful data acquisition and environmental monitoring. This initiative aligns with federal interests in maintaining a cutting-edge observational system.
The U.S. Geological Survey's Landsat Flight Operations (LFO) Project document outlines a Configuration Management (CM) Policy aimed at maintaining the integrity of documentation, hardware, and software related to the Land Satellites Data System (LSDS) Program. Key sections include the purpose and scope of CM, roles and responsibilities, configuration control processes, and the protocol for Change Requests (CRs). The document emphasizes the need for formal change control governed by Configuration Control Boards (CCBs), detailing the structure and membership of these boards. It categorizes Configuration Items (CIs) that require formal change procedures, alongside Non-Configured Items (Non-CIs) which are managed differently. The CM process is designed to ensure systematic reviews and documentation of changes, focusing on the integrity and traceability of assets. This CM Policy is essential for the effective management of Landsat's ongoing mission to collect and distribute remote sensing data critical for monitoring Earth's surface changes over time, aligning with the objectives set out in the Land Remote Sensing Policy Act of 1992.
