9 GNSS Satellite Navigation
9.1 Time Zone and Daylight Saving
GPS system time differs from the universal time scale (UTC) by the number of leap seconds which have been
inserted into the UTC time scale since GPS was initiated in 1980. The current number of leap seconds is
part of the navigation message supplied by the satellites, so the internal real time of the GNS181 is based
on UTC time scale. Conversion to local time and annual daylight saving time can be done by the receiver’s
microprocessor if the corresponding parameters are set up by the user.
