Navigation Systems Analyst / Engineer

Introduction: The Johns Hopkins University Applied Physics Laboratory (APL), a national leader in scientific research and development, located midway between Baltimore and Washington, DC is seeking a Navigation Systems Analyst / Engineer.

Job Summary: Perform analysis of navigation system performance, primarily of US Navy submarines.


  • Evaluate submarine navigation system accuracy and reliability using data from inertial navigation systems, navigation-aid sensors and ship system interfaces (sensors include GPS, as well as sonar and other acoustic devices), determine impact of ship maneuvers and of environmental conditions on navigation performance, assess crew performance of duties impacting the navigation system and maintain understanding of the navigation system equipment, software and interfaces as these change due to upgrades and modifications. (30%)
  • Develop analysis methodology and software as required to perform navigation system evaluations. Develop and tune navigation system simulations and perform special studies to evaluate concepts for the next generation submarine navigation system. (30%)
  • Perform system engineering tasks for current and future US Navy navigation systems. (20%)
  • Support navigation system testing at field test sites and at-sea on US Navy surface ships and submarines. (10%)
  • Document and present performance evaluation and analysis results to colleagues, US Navy sponsors and other customers. Provide debriefs and training for submarine crews. (10%)

Note: This job summary and listing of duties is for the purpose of describing the position and its essential functions at time of hire and may change over time.

Required Qualifications:
