Time Tags
POS attaches time tags to all of its outputs to permit synchronization with data from other sensors or
systems. The time tag is based on Universal Time Coordinated (UTC), GNSS, POS or User time; has a
resolution of 1
μ
s; and has an accuracy of less than 10
μ
s.

on the MV-POSView Controller menu bar to display
(Figure 24) the settings.
Note
: UTC and GPS Times are not identical. Due to the occasional need for the addition of a leap
second to UTC, there is an integer difference between UTC and GPS Time. Transitions between the
seconds are precisely coincident between the two times.
