* The default frequency in MHz that is used for calculating Doppler and free space path loss in the Satellite Data table.
* The units used to display azimuth and elevation to the target satellite. This can be in degrees, minutes and seconds or decimal degrees.
* The number of points used for ground tracks on the map. More points result in smoother tracks, but require more processing.
* Whether times are displayrf in the local time zone or UTC.
* Which rotators are displayed on the polar chart. This can be All, None or Matching target. When Matching target is selected, the rotator will
only be displayed if the source in the Rotator Controller is set to this Satellite Tracker and Track is enabled.
* The format used for displaying dates. E.g. yyyy/MM/dd
* Whether times are displayed in the local time zone or UTC.
* Whether to draw the satellites on the map.
