At Relative Dynamics we value knowledge as a process rather than knowledge as an answer. Founded in 2011 our goal is to define the new space era by continuously pushing the boundaries of engineering models services and technology development. Visit us at www.relativedynamics.space.

Relative Dynamics Inc. is seeking to hire a Spacecraft Guidance, Navigation, and Control (GNC) Engineer to provide support to end users on a variety of issues and to identify, research, and resolve technical problems.

What You'll Get to Do:

• Perform GNC Hardware (HW) component trade studies, selection, and subsystem design
• Support systems engineering development of mission Concept of Operations (CONOPS)
• Generate and optimize Design Reference Missions trajectories and implement guidance algorithms
• Develop navigation and orbit determination algorithms and processes
• Design control laws to meet vehicle performance and stability margin requirements
• Implement GNC Flight Software (FSW) state machine
• Define GNC subsystem Fault Detection, Identification, and Response (FDIR)
• Develop high-fidelity GNC simulation and Hardware-in-the-Loop (HIL) test frameworks
• Integrate and validate GNC FSW and HW components
• Support internal and external design reviews
• Execute GNC subsystem verification and validation using HIL and Monte Carlo simulation
• Support flight activities and analyze flight performance data

  • Orbit modeling and simulation software such as GMAT, STK, or FreeFlyer
  • Knowledge of GNC sensors and actuators
  • Hands-on experience with IMU, reaction wheels, star trackers, gyroscopes, and other GNC HW
  • Non-linear and linear system analysis and control principles and tools to design feedback control systems
  • Blended attitude solutions from a variety of sensor data
  • Spacecraft on-orbit operations and anomaly resolution
  • NASA’s GPS-Enhanced Onboard Navigation System (GEONS)
  • NASA’s Core Flight System (CFS)
  • Rendezvous, Proximity Operations, and Capture/Docking (RPOC/D) trajectories and algorithms
  • MS or PhD

What You Won't Do:

• Feel stuck as we offer great opportunities to advance and learn
• Feel like a number as we're a close-knit bunch and always have each other’s backs
