Question	How do I create a TLE file?

Answer

To create a TLE file, you must first start with a propagated satellite object. Once you have a satellite in your scenario, you can continue.

Next, you need to open the Generate TLE tool. Right-click your satellite and in the shortcut menu select Satellite > Generate TLE….
Note: The Generate TLE Tool requires an STK SatPro license in STK 12.2 and older, or STK Premium Space or Enterprise in STK 12.3 and newer.

How to Find the Generate TLE Tool

This will open the Generate TLE dialog box. Once you are in the Generate TLE Tool GUI, you can modify any of the associated properties to generate a proper TLE. The information about each entry is listed in the STK Help; click the [Help] button or go to this link.

Generate TLE Tool Window

If you click the [Element Set…] button under Reports, you will generate the TLE for your satellite. Below is an example output.
