Angle data in Sample datagram
The fore-and-aft (alongship) and athwartship electrical angles are output as one 16-bit word.
The alongship angle is the most significant byte while the athwartship angle is the least significant byte. Angle data is expressed in 2’s complement format. The electrical angle must be multiplied with the angle sensitivity to get the target position relative to beam centre. Positive numbers denotes the fore and starboard directions.
