Network Time Protocol

Clock synchronization is important for ROS. Chrony has been found to be the best ntp client over lossy wireless. In case of robot behaves strange when messages are sent from PC application(like rviz, rqt, or ros node running in PC), you need clock synchronization.

  1. Install Chrony
    • sudo apt-get install chrony
  2. manually sync NTP
    • sudo ntpdate ntp.ubuntu.com
