    JOB DESCRIPTION: Geodetic Orbit Scientists monitor Global Navigation Satellite Systems, acquire and analyze satellite data, and produce accurate products for the National System for Geospatial-Intelligence (NSG). They develop, evaluate, and use algorithms and tools to provide integrity monitoring and determine precise ephemerides and other information. They analyze satellite ranging and timing information in order to identify anomalies in both real time and post-fit scenarios. These analysts handle technical and logistical details pertinent to remote command and control of a worldwide network of satellite tracking stations. They provide in-depth technical expertise on satellite issues to customers, and represent NGA in community forums establishing doctrine and policy.

    ADDITIONAL INFORMATION: The Global Navigation Satellite Systems (GNSS) Division is seeking a GEOINT Analyst (Geodetic Orbit Sciences). The GNSS Division has responsibility for a wide range of functions and tasks which require an understanding of satellites and their characteristics (hardware and software), orbital analysis, and geodetic sciences. Current functions include producing daily precise, rapid and predicted ephemerides for GPS satellites using data from NGA and United States Air Force (USAF) ground monitoring stations, as well as daily generation of Earth Orientation Prediction Parameters (EOPP), Defense Meteorological Satellite Program (DMSP) ephemeris, and GPS precise ephemeris data for Satellite Tracking (SATRAK) as needed. The Monitor Station Network Control Center (MSNCC) has responsibility for operating a worldwide GPS monitor station network, which is controlled via the MSNCC in St. Louis, MO and Springfield, VA. Data from our monitor stations is provided near real-time to the USAF for integrity monitoring and used in updating time and position information broadcast by GPS satellites. Daily GPS data in Receiver Independent Exchange (RINEX) format is also supplied to the International GNSS (Global Navigation Satellite System) Service (IGS). GNSS also generates a daily GPS precise ephemeris in batch production mode using Estimation and Prediction of Orbits and Clocks to High Accuracy (EPOCHA) software and is currently testing and evaluating a version of EPOCHA designed to provide near realtime 5-minute GPS precise ephemeris on a 24x7 basis. OTHER REQUIREMENTS: The MSNCC is monitored 24x7 and shift work/rotations, within this position, may be required. Shift rotations may be required. Weekend and Holiday shifts may be required. Occasional travel may be required. Once employed with GNSS, the employee will be deemed Emergency Essential and will not be subject to facility closures or reporting delays; employee must report for duty on time due to shift and mission requirements.
