generate
public TLE generate(SpacecraftState state, TLE templateTLE)
Generate a TLE from a given spacecraft state and a template TLE.The template TLE is only used to get identifiers like satellite number, launch year, etc. In other words, the keplerian elements contained in the generated TLE are based on the provided state and not the template TLE.
- Specified by:
generate
in interfaceTleGenerationAlgorithm
- Parameters:
state
- spacecraft statetemplateTLE
- template TLE- Returns:
- a TLE corresponding to the given state
-
getRms
public double getRms()
Get the Root Mean Square of the TLE estimation.Be careful that the RMS is updated each time the
generate(SpacecraftState, TLE)
method is called.- Returns:
- the RMS
-
