9.3.1.2 NAVIGATION Window
On the navigation window are displayed the following data:
● Navigation data: Heading and attitude (Heading, Roll, Pitch), Position (UTM Zone, UTM
North, UTM East, Depth, Speed), Heave (Heave, Surge, Sway), Time (Run Time, UTC
Time), Acoustics (Tracking, Noise Lev., Noise lvl H1, Noise lvl H2, Noise lvl H3, Noise
lvl H4), GPS (Attitude, Mode, Std. Dev, Time)
● Positioned transponder data:
