Default Data for Sharing Assignments

Sources of data for sharing assignments vary in format and in completeness. Where a database contains all the parameters needed in Visualyse Coordinate calculation these will be used in all cases. Where some parameters are missing, the software needs to assume sensible default values, and these can be adjusted via the Settings menu.

Set the Default Antenna type – select a Radiation pattern to use and default parameters (diameter, peak gain and efficiency etc).

Select the Radiation pattern from the drop down list on the left. Select the parameters to use as defaults from the drop down on the right and enter the values in the field or fields below.

Where sharing services do not have an antenna azimuth specified, you can select two options. The worst case assumption is that the sharing station points directly at the earth station. Alternatively, the database may have a second station associated with the one under consideration. In this case you can point the antenna towards the associated station.

You can also specify a default height above the terrain and default transmit power.
