Hi,

Provided I have these three parameters I can acquire from the vehicle itself:

Speed, steering angle, heading, what's the most accurate way to calculate angular velocity for geometry_msgs/Twist for odometry? Is that advisable or do I need proper wheel encoders?

Do you also have the kinematics of your vehicle?

@gvdhoorn, Ackermann steering if that's what you are asking? Front wheel drive.
