Dragon Guidance Navigation Control (GNC) Bay

 

Dragon GNC Bay

The sealed equipment bay on the forward side of Dragon (shown with the bay door open in the photo below) contains state-of-the-art sensors essential to Dragon Guidance, Navigation, and Control (GNC). Optical sensors, laser-based range sensors, and inertial sensors are used during Dragon free-flight and approach to the space station.

Redundant sensors are also connected to the fault-tolerant avionics suite, increasing the system’s safety and reliability. The sensors are concealed by the GNC bay door, which opens on ascent to allow sensors to take measurements and closes to protect them during reentry.
