Job Description:

Are you passionate about spacecraft Navigation?Would you love to apply your technical knowledge and creativity to make innovative contributions to some of the nation's cutting-edge space missions?Are you searching for a collaborative, fulfilling work environment?If so, we're looking for someone like you to join our team at APL.We are seeking creative engineers to help us develop, analyze, test, and deliver spacecraft Navigation systems and analysis algorithms for both Civil Space (NASA/NOAA) and National Security Space missions. Our spacecraft reach the extremes of the solar system, from Parker Solar Probe at the Sun, formation flying missions and assured PNT at Earth, New Horizons at Pluto, and now Dragonfly at Titan. We would love to have you apply your talents to our challenges. As a member of our team, you will contribute to the development of some of our nation's most critical space missions, joining an industrious team of engineers who strive to deliver game-changing solutions. You will have the opportunity to support both pre-launch spacecraft development and post-launch operations performance analysis and system updates. We are passionate about our work, striving to cultivate an environment of partnership and collaboration, and committed to making critical contributions to critical challenges.As a Navigation Engineer...

  • Your primary responsibility will be assisting in the design, development, and delivery of the Dragonfly Mobility Navigation subsystem.
    • You will work closely with other navigation engineers and the Dragonfly mobility team to create a system design that both meets science mission objectives and navigation requirements.
    • You will assist with the integration and test of spacecraft through scenario testing and data analysis.
    • You will support spacecraft operations through processing of optical navigation and lidar data to compute the lander postion on the surface of Titan.
    • You will develop navigation analysis tools for pre- and post-launch activities.
    • You will also be responsible for assisting in the design, development, and delivery of other Navigation subsystems. For example:
      • Pursuing Independent Research and Development (IR&D) efforts to define and prototype the next generation of Positioning, Navigation, and Timing (PNT) systems.
      • Innovating our GPS receiver and onboard orbit determination Extended Kalman filters for various Earth orbiting spacecraft.
      • Implementing, testing, and analyzing navigation algorithms: Extended Kalman filters, batch estimators, particle filters, sigma point filters, etc.
      • Use commercially available tools such as ODTK and STK to determine a spacecraft's state as a function of time.
      • Implementing optimization methods such as: quasi-Newton, Linear/Quadratic Programming, Genetic Algorithm, and Levenberg-Marquardt, on a variety of studies.
      • Implementing navigation algorithms in real-time embedded software using SIMULINK and C/C++.
      • Contribute directly to our continuously evolving code-base and navigation capabilities.QualificationsYou meet our minimum qualifications for the job if you...
        • Possess an MS in Aerospace or Electrical Engineering or related field.
        • Have experience in Extended Kalman filters and other Bayesian Estimation or target trackers,.
        • Are skilled in analytical and numerical computing software, such as MATLAB and C/C++.
        • Are eager to learn new concepts and apply them to develop novel technologies for spacecraft PNT.
        • Are able to obtain a Top Secret security clearance. If selected, you will be subject to a government security clearance investigation and must meet the requirements for access to classified information. Eligibility requirements include U.S. citizenship.
        • Can demonstrate that you are fully vaccinated against COVID-19. To ensure the safety and well-being of the community, APL has established a policy requiring that all staff be vaccinated against COVID-19. All staff members must provide proof of full vaccination or have an approved medical or religious accommodation by their start date.You'll go above and beyond our minimum requirements if you...
          • Possess a PhD in Aerospace or Electrical Engineering or related field.
          • Have spacecraft mission experience in either design, analysis, development, testing, or operations of navigation subsystems.
            • Even more desirable is previous work in on optical (image) and lidar assisted navigation systems.
            • Have previous experience or significant coursework on the design, implementation, and optimization of embedded software.
            • Have previous experience in the design, analysis, and development of navigation systems for interplanetary spacecraft.
            • Able to implement and analyze image processing and lidar navigation techniques: Terrain-Relative Optical Navigation and hazard detection, such as those used on ALHAT (Autonomous Landing and Hazzard Avoidance Technology).
            • Have experience with GPS and GNSS, especially for spacecraft orbit determination.
            • Are able to obtain a TS/SCI security clearance.Why work at APL?The Johns Hopkins University Applied Physics Laboratory (APL) brings world-class expertise to our nation's most critical defense, security, space and science challenges.
