Responsibilities

ADDITIONAL INFORMATION: Geodetic Orbit Scientists apply orbital mechanics and network systems analysis to acquire, process and analyze Global Navigation Satellite System (GNSS) satellite data. 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 provided in-depth technical expertise on GPS satellite issues to internal and external customers, and represent NGA in external community forums establishing DoD and Intelligence Community doctrine and policy. Additionally, the GNSS division updates and maintains the WGS 84 Reference Frame. This position entails leading a team of geodetic orbit scientists and analysts to ensure modernization and recapitalization of the GNSS systems and products, sustainment and innovation of tradecraft, development of skills essential to the division mission, and coordination with mission partners. Competitive applicants shall possess a strong STEM background and/or extensive experience in GNSS and/or have leadership attributes. Leadership experience is highly desired along with the ability to anticipate future needs and guide/mentor teams in transformational initiatives. For this position, strong communication skills are needed as well as the ability to effectively work across NGA organizational lines and with external mission partners. The GNSS division's 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 and is staffed by four branches comprising of two shifts, Days and Evenings. Data from the monitor stations is provided near real-time to the USSF for GPS satellite integrity monitoring and used in updating time and position information broadcast by GPS satellites. Daily GPS data in Receiver Independent Exchange format is also supplied to the International GNSS Service. The Division 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 real-time five minute GPS precise ephemeris on a 24x7 basis. TDY may be required when applicable for training, meetings and other events. This position is eligible for an INCENTIVE: The selected candidates may be offered an incentive as part of the offer of employment, based on budget availability. To receive the incentive, the selected candidate must sign a service agreement depending on the approved amount or duration of the incentive.
