Note: Commas separate all items. Two attitude data strings are available. The strings are identical except for the
definition of roll and pitch angles. One string uses Tait-Bryan angles and the other uses TSS angles. Use the MV-
POSView Controller program to set the required angle convention. Refer to COM Port Set-up on page 4-14 for
instructions and Mounting Angles on page 2-29 for a definition of the Tait-Bryan angles. The information is valid in the
vessel frame, except for heave, which is valid in the sensor 1 frame.
