AbstractNavigationMessage

protected AbstractNavigationMessage(double mu,
                                    double angularVelocity,
                                    int weeksInCycle,

                                    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)

AbstractNavigationMessage

protected AbstractNavigationMessage(FieldAbstractNavigationMessage<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:
