POSITION TITLE: MATHEMATICIAN
PAY PLAN: GS
FEDERAL JOB SERIES: 1520
This position is located in the Time Transfer Division, Time Service
Department, at the United States Naval Observatory (USNO), Washington, D.C.
As part of a team consisting of engineers, mathematicians, and technicians,
the incumbent maintains and develops mathematical and statistical techniques
to monitor designated radio navigation and timing systems of interest to the
Department of Defense (DoD) and associated civilian users, such as GPS and
WAAS. Also monitors the timing transmissions of Loran and Two-Way Satellite
Time transfer (TWSTT) to remote sites. Diagnoses problems in hardware,
software, or mathematical and statistical algorithms. Interfaces all
monitoring equipment to the departmental computers and ensures that the
mathematical and statistical algorithms used in the different systems are
complementary. Reduces and processes radio timing data. As new satellites or
systems are made operational, develops new software and mathematical and
statistical algorithms or clones and modifies existing software and
algorithms to accommodate the new data. Performs analysis on the radio
timing data, including both operational and developmental statistical
analysis and modeling of satellite performance and of time-transfer using
carrier-phase and/or code-based techniques. Studies and applies mathematical
and statistical methods such as adaptive ARIMA or ARMA models for combining
data from different systems. Develops and implements mathematical and
statistical algorithms for error analysis and error removal. Coordinates
operations between the USNO and designated satellite-based control
facilities. Responsible for the maintenance of the data and status files
which are accessed by users via the USNO Automated Data Service (ADS).
