GN&C

How Do You Control a Spacecraft?

GNC stands for Guidance, Navigation, and Control. This subsystem is responsible for determining the orientation of the spacecraft in orbit and controlling that orientation. The subsystem ensures the spacecraft stays on its orbital path in order to provide its intended services. GNC also provides attitude control, helping with the mitigation of tumbling in space as well as ensuring our antennas are always pointed to our ground station on Earth.

 

GN&C capabilities:

  • Mission planning
  • Dynamics Simulations
  • Guidance of all mission phases
  • Navigation: system architecture trade studies, sensor selection, filter development
  • Control: algorithms, stability analyses, controller design, modeling, and simulation
  • Sensor hardware development
  • Closed loop calibration, testing, and qualification
