Use this property window to import files from /data/satellites directory of vsTASKER.
These satellite database files contain TLE information provided by Celestrack website (http://www.celestrak.com/NORAD/elements/)
Some of these satellites are decayed and thus, SGP4 propagator will reject them.
Nevertheless, the Two-Body (or J2) propagator will be able to revive them based on the orbital elements.
Create a new Database.
Select the Template Satellite, then Earth.
Go to Navigation category, then click on icon, then icon and finally to select the TLE database to load.
In the list, select the orbits you want to instantiate locally (for ie: geodetic.txt)
Select the Satellite entity defaulted in the Catalog (or any other you have created)
Select the Propagator component you will use. It must be SGP4 for any TLE orbit, Two-Body for Keplerian orbits
Click on the button.
vsTASKER will create the orbits and will associate a new satellite Entity.
