Constructor Details

SBASPropagatorBuilder

@DefaultDataContext
public SBASPropagatorBuilder(SBASOrbitalElements sbasOrbElt)

Initializes the builder.

The SBAS orbital elements is the only requested parameter to build a SBASPropagator.

The attitude provider is set by default be aligned with the EME2000 frame.
The Earth gravity coefficient is set by default to the SBAS_MU.
The mass is set by default to the DEFAULT_MASS.
The ECI frame is set by default to the EME2000 frame.
The ECEF frame is set by default to the CIO/2010-based ITRF simple EOP.

This constructor uses the default data context.

Parameters:

sbasOrbElt - the SBAS orbital elements to be used by the SBAS propagator.

Since:

12.0
