As a GNSS-R/Bistatic Radar Scientist at Spire, you will be an integral part of a small but agile team focused on developing and operating a GNSS bistatic radar mission (aka GNSS reflections or “GNSS-R”). You will work across the various disciplines of bistatic radar remote sensing mission design and analysis, GNSS-R receiver processing, GNSS-R retrieval algorithm development, and measurement calibration and validation.
You will work with the world’s premier nanosatellite GNSS receiver design team to implement GNSS-R capabilities on our state-of-the-art CubeSat GNSS payload. You will develop the remote sensing algorithms and codes to turn GNSS-R bistatic radar measurements of the Earth surface into valuable products for a wide variety of global customers, and these products will lead the field in Earth observations from commercial CubeSats. You will have the responsibility to ensure that we deliver high-quality, low-latency Earth remote sensing products and the freedom to pursue novel, high-impact applications. And instead of your ideas and efforts sitting on a shelf or hidden in an academic journal, you will see and experience them actually working in space within months.
Responsibilities of your role:
- Contributing to the mission design and operation of a GNSS-R bistatic radar payload on a large and growing constellation of CubeSats.
- Working with the payload team to implement GNSS-R algorithms into the existing and new versions of the GNSS receiver payload.
- Ensuring the payload can meet measurement requirements, including a robust and precise bistatic radar calibration system.
- Retrieval algorithm development for the conversion of low-level GNSS-R measurements into calibrated measurements of Earth surface bistatic radar cross section and derived products for ocean, land, and sea ice surfaces.
- Conducting thorough calibration and validation of the measurements to improve their quality and to document their accuracy and precision for customers.
- Supporting the commissioning and operation of the GNSS-R payload after launch and performing agile development while on orbit to constantly increase capabilities and improve performance.
Qualifications / Experience:
- Direct experience in satellite or aircraft-based remote sensing or scatterometry.
- Ph.D. or M.S. in remote sensing, preferably satellite microwave radar and/or radiometry, electrical engineering, applied physics, or a related field.
- Strong Linux computer skills.
- Experience with programming and analysis in Python (preferred) or Matlab/Octave.
- Strong background in physics, mathematics, and statistics.
- Knowledge of remote sensing and GNSS signal processing.
- In-depth knowledge in one or more of the following surface remote sensingdisciplines: physical oceanography, terrestrial hydrology, or cryospheric sciences.
- Exceptionally well-organized, with the ability to go as deep as needed in any project to identify and resolve problems.
- Adaptability to new ideas and the ability to push the envelope of GNSS capabilities to deliver unique applications in Earth observations.
