GSOF Messages B
Attitude
This message provides attitude information relating to the vector between the Heading
antenna and the Moving Base antenna. It contains the following data:
• Tilt or vertical angle, in radians, from the Heading antenna to the Moving Base
antenna relative to a horizontal plane through the Heading antenna
• Heading or yaw, in radians, relative to True North
• Range or slope distance between the Heading antenna and the Moving Base
antenna
