		double	lat,
		double	lon,
		double	h,
		double	ve,
		double	vn,
		double	vu,
		int	band ) const

Computes prediction of the Doppler shift for a given time and receiver's position and velocity.

\[f_{d} = - \mathbf{v} \frac{\mathbf{x}^{T}}{\left| \mathbf{x} \right| } \frac{f_{L}}{c} \]

where:

\[\mathbf{v} = \mathbf{v}_{sat} - \mathbf{v}_{rx} \]

\[\mathbf{x} = \mathbf{x}_{sat} - \mathbf{x}_{rx} \]

\[\left| \mathbf{x} \right| = \sqrt{\mathbf{x}\mathbf{x}^{T}} \]
