window. Note that the data are saved in binary file and can be used in two
ways:
visualization through opening the file in “File”, “Open” menu item (see
section “6.1. “Open” item”);
conversation to text file using “Report of experiment“ from “Convert“
menu item (see section “9. Convert Menu”).
“Stop“ button stops data output to the screen and data saving
procedure with no data losses.
Button “Snapshot” is used for fixing the current values of measured
data during continuous run (see section “10.5.2. On-the-fly accuracy test”).
Button “Start/Stop VG3D clb” is used to start or stop the on-the-fly
VG3D calibration process (see section 10.4.4 for more details).
If the data output method “On Request” is chosen in the menu “Options”,
then getting data from the INS is performed by clicking the button . In
case of data saving (if the button “Write” is pressed), the measured data
are written in one file sequentially.
Button “Start/Stop Odometer clb” is used to start or stop the
odometerr calibration process (see section 10.7.1 for more details).
Current orientation angles are displayed in the upper right part of the
window Fig. 5.1, position and velocity data are displayed in the bottom part
of this window. Additional displayed data depend on selected output data
format (see Appendix C for description of data formats). If default “INS OPVT
Output“ data format is chosen then the next data are displayed in the right
part of the window Fig. 5.1:
a) Orientation angles “Heading“, “Pitch“ and “Roll“. In the “INS“ column,
angles calculated in the INS’s microprocessor using the embedded main
algorithm are output. The “Magn/Acc“ column shows orientation angles
calculated in the INS GUI Software using simplified algorithms based on
magnetometers and accelerometers data. Angles in the “Magn/Acc“ column
are auxiliary; they are used by developers only to control operation of the
main algorithm.
