Constructor Detail

GNSSPropagatorBuilder

@DefaultDataContext
public GNSSPropagatorBuilder(GNSSOrbitalElements gnssOrbElt)

Initializes the builder.

The GNSS orbital elements is the only requested parameter to build a GNSSPropagator.

The attitude provider is set by default to be aligned with the EME2000 frame.
The mass is set by default to the DEFAULT_MASS.
The ECI frame is set by default to the EME2000 frame in the default data context.
The ECEF frame is set by default to the CIO/2010-based ITRF simple EOP in the default data context.

This constructor uses the default data context. Another data context can be set using Builder(final GNSSOrbitalElements gpsOrbElt, final Frames frames)

Parameters:

gnssOrbElt - the GNSS orbital elements to be used by the GNSSpropagator.

attitudeProvider(AttitudeProvider provider), mass(double mass), eci(Frame inertial), ecef(Frame bodyFixed)
