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 generate TLE a 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
-
