Specialized experience must demonstrate the following: Experience and possess knowledge in celestial mechanics, orbit determination, geodesy, geophysics, time series analysis, statistics, data analysis software, and/or computer programming/software design.

Experience accomplishing timely analysis and implementation of new processing methods.

Experience originating new techniques in the area of orbit determination, data processing, and/or time series analysis, to develop, transition, and execute USNO capabilities.

Experience formulating new data processing schemes and models that will be used by the international geodetic and astronomical communities.

Experience in and must be familiar with a wide variety of astronomical, geodetic and/or geophysical data and with the associated analysis procedures.

In addition to the BASIC EDUCATION REQUIREMENTS to qualify for a GS-12, your resume must also demonstrate at least one year of specialized experience at or equivalent to the GS-11 grade level or pay band in the Federal service or equivalent experience in the private or public sector.

Specialized experience must demonstrate the following: Experience planning significant projects, advising on instrumentation improvements, software, or procedural methods; and ensures that specialized equipment and software is identified, procured (if necessary), modified, installed, and meets all IA and division requirements.

Experience serving as an advisor to other scientists, specializing in areas such as analysis of orbits of GPS satellites, signals of GNSS satellites, and other data or processes.

Experience in the daily determination of Earth orientation parameters using state-of-the-art methods in software analysis including daily monitoring activities which sometimes occur on weekends.

Experience using software employing complex algorithms to estimate GPS satellite orbits, receiver-and satellite-clock corrections, positions of the earth's rotation pole, UT1 values, and other related quantities from GPS measurements.

USNO's software consists of a unique combination of USNO developed automation routines and high-precision GPS-processing software packages developed by USNO and external scientific organizations.

Volunteer work helps build critical competencies, knowledge, and skills and can provide valuable training and experience that translates directly to paid employment. Major Duties:

• You will serve as an ASTRONOMER in the Earth Orientation Department (EO), GPS Analysis Division of the U.S. NAVAL OBSERVATORY (USNO).
• You will participate in GPS and GNSS analysis activities such as estimating satellite orbits, receiver-and satellite-clock corrections, positions of the Earth's rotation pole, UT1 values, and other related quantities from GPS and GNSS measurements.
• You will be responsible for the daily determination of Earth orientation parameters from GPS and GNSS observations using state of-the-art methods in software analysis including daily monitoring activities.
• You will design, code, test, and implement required software programs, and evaluate/update existing programs.
• You will validate that existing algorithms and inputs that are currently in use at USNO produce accurate estimates from GPS and GNSS estimates.
• You will write and present scientific/technical material to DOD, national, and international audiences and create/update standard operating procedures.
• You will develop and maintain knowledge in celestial mechanics, orbit determination, geodesy, geophysics, time series analysis, statistics, data analysis software, and computer programming/software design.
• You will plan, coordinate, and implement software tests to ensure that compliance is maintained.
