Is gimbal yaw (KeyGimbalAttitude) about true or magnetic north?

[egm108]

Hi, dear support

When I used msdk 4.16 there was clear explanation in api that gimbal yaw is related to true north.
So probably msdk 5x gimbal yaw is about true north too. Right?

My second question is:
if it's true north, what's the behaviour when there are not enough sattelite ( so msdk is not available to define magnetic declination)?

Probably, that'll be relative to magnetic north.

If so, How can I find out from my code what north is used now magnetic or true?

Thank you as always!

Dear Developer,

1、Yes, you can check the description of KeyGimbalAttitude. It indeed refers to the true north direction in the obtained attitude.

2、When the GPS signal is poor, the acquired value may have errors.. It's similar to obtaining this value indoors. Usually, if the GPS signal is too poor, flight is not possible. Currently, the MSDK cannot determine through code whether the current flight control is using magnetic north or true north.
