TLE Generation - VALAR Documentation

For the complete documentation index, see llms.txt.

TLEs (Two-Line Element sets) are automatically generated on-demand from your latest state vector. Access them through the cheatsheet component in the application header.

Accessing TLEs

Open the cheatsheet from the application header
The TLE is generated automatically when the cheatsheet opens
View the raw TLE lines
Click the copy button next to the TLE to copy it to your clipboard

How It Works

Aspect	Behavior
State Vector Used	Always the latest state vector (most recent epoch within last 30 days)
Selection	Automatic (users cannot manually select which state vector to use)
Refresh	Regenerated fresh each time the cheatsheet opens (not cached)
Spacecraft	Uses the currently selected spacecraft

The TLE reflects your most recent state vector data. If you need a TLE from a specific epoch, ensure that state vector is your latest before opening the cheatsheet.

TLE Format

The generated TLE follows the standard NORAD two-line format:

1 NNNNNC NNNNNAAA NNNNN.NNNNNNNN +.NNNNNNNN +NNNNN-N +NNNNN-N N NNNNN
2 NNNNN NNN.NNNN NNN.NNNN NNNNNNN NNN.NNNN NNN.NNNN NN.NNNNNNNNNNNNNN

For details on the TLE format and field definitions, see the TLE Format documentation.
