Constructor Details

AbstractAlmanac

protected AbstractAlmanac(double mu,
 double angularVelocity,
 int weeksInCycle,
 TimeScales timeScales,
 SatelliteSystem system)

Constructor.

Parameters:

mu - Earth's universal gravitational parameter

angularVelocity - mean angular velocity of the Earth for the GNSS model

weeksInCycle - number of weeks in the GNSS cycle

timeScales - known time scales

system - satellite system to consider for interpreting week number (may be different from real system, for example in Rinex nav, weeks are always according to GPS)

AbstractAlmanac

protected AbstractAlmanac(FieldAbstractAlmanac<T,A> original)

Constructor from field instance.

Type Parameters:

T - type of the field elements

A - type of the orbital elements (non-field version)

Parameters:

original - regular field instance

Method Details

getPropagator

public GNSSPropagator getPropagator(Frame inertial,
 Frame bodyFixed)

Get the propagator corresponding to the navigation message.

The attitude provider is set by default to be aligned with the inertialframe.
The mass is set by default to the DEFAULT_MASS.

Parameters:

inertial - inertial frame, use to provide the propagated orbit

bodyFixed - body fixed frame, corresponding to the navigation message

Returns:

the propagator corresponding to the navigation message

Since:

14.0

See Also:

• getPropagator(AttitudeProvider, Frame, Frame, double)

getPropagator

public GNSSPropagator getPropagator(AttitudeProvider provider,
 Frame inertial,
 Frame bodyFixed,
 double mass)

Get the propagator corresponding to the navigation message.

Parameters:

provider - attitude provider

inertial - inertial frame, use to provide the propagated orbit

bodyFixed - body fixed frame, corresponding to the navigation message

mass - spacecraft mass in kg

Returns:

the propagator corresponding to the navigation message

Since:

14.0
