Overview

This package provides shared memory driver for various NTP daemons (such as ntpd and chrony).

Time server configuration

ntpd

Just add to /etc/ntp.conf:

### GPS SHM driver (unit 2)
server 127.127.28.2 minpoll 4 maxpoll 4
fudge 127.127.28.2 time1 0.5 stratum 12 refid ROS

chrony

Add this to /etc/chrony/chrony.conf:

### SHM driver (unit 2)
refclock SHM 2 delay 0.5 refid ROS

Note that chrony does not allow set stratum (topic not very accurate), but i hope delay option does same thing.

Node

This node sends time from topic to time server.

Subscribed Topics

~time_ref (sensor_msgs/TimeReference)
  • Time source topic.

Parameters

~shm_unit (int, default: 2)
