Satellites Number: Click to open the plot to show the relation between number of
satellites, which can be reached, and the GPS time. This tool is used to show the number
of satellites can be reached by the device each time during the data acquisition. Satellites
number is shown on the Y-axis. The green part on the plot means the number of satellites
is good at that time. The blue part on the plot means the number of satellites is just
acceptable at that time. While the red part means the satellite number is too few to meet
the requirement. The insufficient GNSS signal will result in poor data quality. If the
number of satellites can be reached by the device is too few during a period of data
acquisition, user can select the time period and right-click on that. Then click “Go to
Time” button to find out the corresponding period on the trajectory.
Floating/Fixed ambiguity status: Click to show the plot of ambiguity resolution status.
This is used to show the situation of cycle ambiguity resolution. If the status is shown as
green on the plot, it means the cycle ambiguity resolution is fixed. If it is red on the plot,
it means the cycle ambiguity resolution is floating.
