Note that the ntpd 28 driver (shared memory driver), see below, which allows the use of gpsd functions, is not marked with an "o", even if PPS is used. If it works correctly, it will be marked with "*". | |||

Daemon gpsd is a unified Protocol of interaction with the receivers of the satellite signals of GPS/GLONASS. In our case, we will use it as an intermediate layer between the module and the ntpd server (driver with code 28). | |||
The daemon is installed by the command | |||
<pre>apt-get install gpsd</pre> | <pre>apt-get install gpsd</pre> | ||

In ntpd server settings we need to specify two new sources of exact time: NMEA and PPS. |
