Class GLONASSNumericalPropagatorBuilder

java.lang.Object

org.orekit.propagation.numerical.GLONASSNumericalPropagatorBuilder

public class GLONASSNumericalPropagatorBuilder
extends Object

This nested class aims at building a GLONASSNumericalPropagator.

It implements the classical builder pattern.

Caution: The Glonass numerical propagator can only be used with GLONASSFdmaNavigationMessage. Using this propagator with a GLONASSAlmanac is prone to error.

Constructor Details

GLONASSNumericalPropagatorBuilder

@DefaultDataContext
public GLONASSNumericalPropagatorBuilder(ClassicalRungeKuttaIntegrator integrator,
 GLONASSOrbitalElements glonassOrbElt,
 boolean isAccAvailable)

Initializes the builder.

The attitude provider is set by default to EME2000 aligned in the default data context.
The mass is set by default to the DEFAULT_MASS.
The data context is by default to the default data context.
The ECI frame is set by default to the EME2000 frame in the default data context.

Parameters:

integrator - 4th order Runge-Kutta as recommended by GLONASS ICD

glonassOrbElt - the GLONASS orbital elements to be used by the GLONASSNumericalPropagator.

isAccAvailable - flag for availability of the projections of accelerations transmitted within the navigation message
