2.1 **[SATAZ Main Window]{.underline}**

Upon start up some of the fields are initialized with values from a
previous execution. Figure 2 shows the **SATAZ** start up window. If the
user doesn=t wish to see this window at program start up in the future,
he/she should uncheck the Show next time box. Figure 3 shows the
**SATAZ** main window at start up.

2.2.2.1 **[Deg/Min/Sec & Decimal \* Command]{.underline}**

To convert the latitude and longitude values from decimal degrees to
degrees, minutes and seconds, the user should select the **Deg/Min/Sec**
command button. The latitudes and longitudes are converted and displayed
in the window. The command button then changes to **Decimal \*** so that
the user can convert the latitudes and longitudes back to decimal
degrees if he/she wishes. Figure 20 shows the output window with the
**Deg/Min/Sec** command button. Figure 21 shows the output window after
the **Deg/Min/Sec** command button was selected and was changed to
**Decimal \***.

To exit from the output window but not the program, the user should
select the **OK** command button that will close the output window and
return control to the main input window.

3.2 **[Program Results]{.underline}**

The program calculates and displays the azimuth angle relative to north,
original elevation angle, corrected elevation angle, satellite pointing
angle, and slant angle to antenna on a separate output window. Figure 23
shows the output window.
