Summary Geodetic Orbit Scientists monitor Global Navigation Satellite Systems (GNSS), acquire and analyze satellite data, produce and maintain the WGS 84 reference frame, and contribute geodetic products (e.g., GNSS orbits) to the DoW, IC, and civilian partners. They plan, develop, evaluate, and use algorithms and tools to provide integrity monitoring and determine ephemerides and other information. They Responsibilities ADDITIONAL INFORMATION: The National Geospatial-Intelligence Agency (NGA) serves as the world leader in providing timely, relevant, accurate, and actionable geospatial intelligence (GEOINT). NGA's civilian, military, and contract personnel evaluate imagery, maps, charts, multiple layers of foundation data - such as terrain, elevation, and gravity - and the full spectrum of visible and invisible light in order to help users visualize what is happening at a particular place and time. Our intelligence officers go beyond describing 'what, where, and when' to revealing 'how...
