Constructor Detail

Builder

public Builder(GPSOrbitalElements gpsOrbElt)

Initializes the builder.

The GPS orbital elements is the only requested parameter to build a GPSPropagator.

The attitude provider is set by default to the DEFAULT_LAW.
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.

Parameters:

gpsOrbElt - the GPS orbital elements to be used by the GPSpropagator.
