The Tracking Systems and Application Section provides world-leading capability and expertise in a wide range of technologies that are critical to spacecraft tracking and related applications. The Section supports algorithm development, calibration and validation of NASA’s satellite altimeter missions as well as NASA’s deep-space missions by providing to the JPL navigators unique and extremely precise radiometric sources and data types. The Section provides the Deep Space Network (DSN) with precision atomic frequency and time references and distribution systems. The Section also delivers to JPL navigators a host of other products that are required for deep space navigation such as celestial and terrestrial reference frame coordinates, Earth orientation parameters, and calibrations to account for the effects of the Earth’s troposphere and ionosphere on radiofrequency metric tracking data-types.
For terrestrial and near-Earth users the Section offers the highest accuracy Global Navigation Satellite System (GNSS)-based positioning and timing products and services. The Section also performs extensive scientific investigations using its technologies in the areas of planetary dynamics, astrophysics, astrometry and radio astronomy, gravitational waves, geophysics, and fundamental physics.
You will be a Research Technologist in the Near-Earth Tracking Applications (NETA) Group undertaking cutting-edge research and development in algorithms, calibration, and validation of NASA’s satellite altimeter missions, including, but not limited to the Jason and Sentinel-6 series. Work in teams to contribute to research and development of science data system algorithms and calibration/validation activities for the suite of JPL-supported altimetry missions: Jason-1, Jason-2, Jason-3, Sentinel-6, and SWOT missions. Contribute to the end-to-end calibration and validation of each component of the measurement system and the science data products for these missions. Apply established approaches, and contribute to the development of novel approaches, for calibration and validation of satellite altimeter measurement systems to identify and mitigate errors in those systems. Perform routine quality control, calibration and validation of science data products for these missions. Contribute to publication in the peer-reviewed literature, as well as presentations at professional society and altimetry mission science team meetings. Contribute to proposals to support related research activities. Use skills in Python and C++ to develop new, or maintain existing, satellite altimeter measurement system calibration and validation tools.
The NETA group performs cutting edge satellite altimetry calibration and validation in support of NASA’s satellite altimeter missions, as well as advanced research and applications in GNSS positioning and signal analysis. Come and join our dynamic team!
