Configuring Time (NTP) Settings

The router can be configured to synchronize its internal clock with a time server on the Internet using the Network Time Protocol (NTP). If NTP is not enabled, the router synchronizes with GNSS. If both GNSS and NTP are enabled, NTP time will be used.

Time Source

Under Time Source, you’ll find what protocol is providing the system time. In the example above, the time source is NTP (NTP is the priority when both NTP and GNSS are available). If the NTP server cannot connect but GNSS has a “fix acquired”, the time source will be GPS-NMEA. When both NTP and GNSS are down, the time source is NITZ, which comes from the cellular network (when the cellular radio can retrieve it).

NTP

Under NTP, you can configure AirLink OS to use your own NTP Server or another NTP Pool.

• SERVICE: Enables NTP update of the system time. When disabled, the system time comes from GPS-NMEA if a location antenna is connected, or from the cellular network.

• CURRENT NTP SERVER: The current NTP server may be automatically assigned from the default NTP Pool, or a manually assigned server that you’ve configured below.

• NTP SERVERS: Click an empty line to enter a NTP Server IP address, or fully qualified domain name.

• NTP POOLS: Click an empty line to enter another NTP Pool.
