Constructor Detail

Builder

@DefaultDataContext
public Builder(GLONASSOrbitalElements glonassOrbElt)

Initializes the builder.

The GLONASS orbital elements is the only requested parameter to build a GLONASSPropagator.

The attitude provider is set by default to the DEFAULT_LAW 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.
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 GLONASSOrbitalElements gpsOrbElt, final DataContext dataContext)

Parameters:

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

See Also:

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

Builder

public Builder(GLONASSOrbitalElements glonassOrbElt,
               DataContext dataContext)

Initializes the builder.

The GLONASS orbital elements is the only requested parameter to build a GLONASSPropagator.

The attitude provider is set by default to the Propagator.getDefaultLaw(Frames).
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:

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

dataContext - the data context to use for frames and time scales.

Since:

10.1

Method Detail

attitudeProvider

public GLONASSAnalyticalPropagator.Builder attitudeProvider(AttitudeProvider userProvider)

Sets the attitude provider.

Parameters:

userProvider - the attitude provider

Returns:

the updated builder

mass

public GLONASSAnalyticalPropagator.Builder mass(double userMass)

Sets the mass.

Parameters:

userMass - the mass (in kg)

Returns:

the updated builder

eci

public GLONASSAnalyticalPropagator.Builder eci(Frame inertial)

Sets the Earth Centered Inertial frame used for propagation.

Parameters:

inertial - the ECI frame

Returns:

the updated builder

ecef

public GLONASSAnalyticalPropagator.Builder ecef(Frame bodyFixed)

Sets the Earth Centered Earth Fixed frame assimilated to the WGS84 ECEF.

Parameters:

bodyFixed - the ECEF frame

Returns:

the updated builder

dataContext

public GLONASSAnalyticalPropagator.Builder dataContext(DataContext context)

Sets the data context used by the propagator. Does not update the ECI or ECEF frames which must be done separately using eci(Frame) and ecef(Frame).

Parameters:

context - used for propagation.

Returns:

the updated builder.

build

public GLONASSAnalyticalPropagator build()

Finalizes the build.

Returns:

the built GLONASSPropagator
