Figure 17), two of which can also be viewed in a graphical plot format. By clicking on View from the
main StarUtil window, you can select a desired NCT binary message and have it displayed in a
tabbed inset window of the main StarUtil window, as shown in Figure 19. This tabbed inset window
can be dragged to another area of your Windows OS desktop and act independently of the main
StarUtil window as shown in Figure 19.

with the exception of the 0xB1 message. The data rate for the 0xB1 message is controlled through
the Rover Navigation &Tracking window; see Figure 15.
