5.4 Time sync
The system uses GNSS as a source of accurate time for synchronization purposes by default. It is also
possible to configure the system to use Network Time Protocol (NTP) in case manual navigation is used
(for example if a GPS signal is not available) or for testing.
5.4.1 Configuring time sync for NTP
This chapter details the requirements and the necessary steps for configuring Network Time Protocol
(NTP) as the time sync method for the system.

Make sure all antennas are connected and the device is powered up. The device must be connected to a
computer with either a USB or an Ethernet cable and have a previously configured IP address on the eth0
interface, available for connection.

2. Check the default gateway. You can set it using the following command:
route add default gw 192.168.0.1
3. Set the DNS-server if you have to. Edit the namespace in resolv.conf, using the follwing command:
vi /etc/resolv.conf
