Assignment Description

ASSIGNMENT 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.

Promotion Opportunity

PROMOTION OPPORTUNITY: Promotion opportunities allow applicants at all band levels to be considered.  Qualifications for NGA positions do not include specific time-in-band requirements.  NGA will emphasize quality of experience, rather than duration, and assess how the quality of the experience demonstrates possession of the knowledge, skills, abilities, and competencies necessary for successful job performance in the NGA occupational structure.

Additional Information

ADDITIONAL INFORMATION: This position has a requirement for participation in shift work.  Periodic evening and weekend work is required.  Overnight shifts are rare, but possible.  Employees are expected to be flexible to changing requirements and supportive when crisis responses require schedule changes.
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 and why.' Our work enables decision advantage for our policymakers, warfighters, intelligence professionals, and first responders. NGA uses a flexible, high mobility career model. Individuals are hired for their overall skills within a specialty such as Geodetic Orbit Scientist, and then placed in various positions throughout the agency once they complete the clearance process. Although currently advertised as a nonsupervisory, permanent, telework-ineligible job posting with occasional travel, it is unknown which specific positions will be available after applicants complete the selection and clearance process. Because of this, aspects of the job such as travel, supervisory, telework, etc. may change, depending on specific positions available at that time. It is also possible that applicants could be hired into a position with specific aspects and then change positions after serving for a period of time in that assignment. Applicants who have completed the clearance process receive final documentation about the nature of the specific position before they make the final commitment to join NGA.
Duties:
1. Identify and analyze geophysical and geodetic orbit data to determine interrelationships and submit recommendations to maintain program requirements.
2. Support continuous data monitoring for GNSS systems. Will require evening and weekend support.
3. Guide research, analysis, and identification of issues by evaluating complex geophysical data sets, identifying deviations in the data, and recommending courses of action.
Additional Application Requirement: You may be asked to complete one or more assessments in addition to the application you submit on this website as part of your application to NGA. These assessments may include but are not limited to: 1) Online questionnaires or assessments that require you to describe your job-related knowledge, skills, abilities, or other characteristics that are aligned with the mandatory and desirable qualifications of this job posting. The information you provide in the application you submit must support the response you provide to this questionnaire. You will receive an email to describe any additional assessments required. Please monitor your emails and complete any required assessments as soon as possible.
