What would be a good ros rate?

Hello,

I have a velodyne VLP16 LiDAR running @10Hz and GPS/IMU data being published @100Hz. I am generating transforms using the GPS/IMU data for the velodyne's transform nodelet. I wanted to know what would be good rate to run my transform generating node? I was also not entirely sure about what kind and how much effect the buffer size would have on the accuracy (dropping transforms?) for this specific application?

Thanks, Sneha

Run it at the same rate as your IMU.

Is the motion fast or slow? 100 Hz seems too fast to me (for most applications).

@AndyZe The setup is on a drone moving at 2-5 m/s.
