USGS and NASA personnel reviewed DPAS technical criteria, the preliminary relationship of the GNE design to the requirements, interface designs, integration and test methods, and LMOC programmatic material. Two programmatic requests-for-actions (RFA) were recorded, neither critical to the success of the outcome of the GPDR.
With the GPDR a success, the Ground System can now proceed to the Critical Design Review, which is planned for Fall 2018 – continuing to ensure the Landsat 9 mission remains on schedule for a launch readiness date of December 2020.
Safeguarding freshwater resources is crucial, and while scientists use a variety of ground-based techniques to gauge water quality, the Landsat program has provided water quality data from orbit for decades.
