double value(double polarAngle,
             double azimuthAngle)
```
    Evaluate phase center variation in one signal direction.
    
    Parameters:
    
    polarAngle - angle from antenna axial direction (zenith angle for receiver antennas, nadir angle for GNSS satellites antennas)
    
    azimuthAngle - angle around axial direction
    
    Returns:
    
    phase center variation in the signal direction (m)
