TLEPropagatorBuilder
@DefaultDataContext public TLEPropagatorBuilder(TLE templateTLE, PositionAngleType positionAngleType, double positionScale, TleGenerationAlgorithm generationAlgorithm)
Build a new instance. This constructor uses thedefault data context
.The template TLE is used as a model to
create initial orbit
. It defines the inertial frame, the central attraction coefficient, orbit type, satellite number, classification, .... and is also used together with thepositionScale
to convert from thenormalized
parameters used by the callers of this builder to the real orbital parameters.- Parameters:
templateTLE
- reference TLE from which real orbits will be builtpositionAngleType
- position angle type to usepositionScale
- scaling factor used for orbital parameters normalization (typically set to the expected standard deviation of the position)generationAlgorithm
- TLE generation algorithm- Since:
- 12.0

. It defines the inertial frame, the central attraction coefficient, orbit type, satellite number, classification, .... and is also used together with thepositionScale
to convert from thenormalized

- scaling factor used for orbital parameters normalization (typically set to the expected standard deviation of the position)dataContext
- used to access frames and time scales.generationAlgorithm
