Need for angle clarification #4

Closed cyrilleponcelet closed 4 years ago

cyrilleponcelet commented 4 years ago

Hi everyones, I got one question, do you think that the angles definition (rx_beam_rotation_phi and consort) are clear enough. I mean do think that we need to add more information to clearly explain to which coordinate system angles are relative to (ie vertical or tx array) ? Or do you think that what is written in table 3 is enough ?

|Transducer coordinate system (TCS) |Centre of transducer face||| 2+|not stabilized |Pointing forward along transducer plane|Pointing starboard along transducer plane|Pointing down orthogonal to transducer plane 2+|stabilized |Pointing forward along transducer plane|Pointing horizontally and perpendicular to x-axis|Pointing down with gravity

One can never be too clear :) If we think that this is an area that might cause confusion, I think we should then provide very clear explanations and even examples (we can do this for rx_beam_rotation_phi, etc).

Should the x-axis for stabilized say 'pointing forward horizontally'?

Should the x-axis for stabilized say 'pointing forward horizontally'? You're probably right. for stabilized system only
