jsc2025e032820 (3/20/2025) --- Left: Astrobee’s guidance, navigation and control (GNC) subsystem. Components shown in black (Matlab/ROS/C++/Python) indicate a replacement pipeline overriding Astrobee’s default GNC subsystem, outlined in red. Right: software interface between GNC components and Astrobee’s finite state machines (FSMs). The FSM-based nodelets are outlined in blue. Image courtesy of Hector Gutierrez.
