9.3 Recording/Playing a log file
u-center allows recording and playing log files. Use the player controls, to record or playback a log file. Select the
log file to be opened through the file menu tool bar. The series of buttons in the player toolbar can be used to
navigate through the log file. The records will be displayed on the navigation display window, in the same way
that live GNSS data is displayed when using u-center. Refer to Player for a description of the menu items.
9.4 Conduct sensitivity tests
u-center is a useful tool for conducting sensitivity tests of GNSS positioning chips and modules and receiver
designs. To do so, under open sky conditions record a log file of the receiver to be tested and an Evaluation Kit
as reference. Make sure that the log files are recorded under the same conditions. Using the Statistic View or
Table View windows from u-center, compare the C/N0 values of the five strongest satellites. With Table view,
export the values to a spreadsheet for analysis.
