Field Detail

ZERO

public static final TopocentricPosition ZERO

Fixed position at origin (p is zero vector).

Constructor Detail

TopocentricPosition

public TopocentricPosition(double elevation,
                           double azimuth,
                           double range)

Build topocentic coordinates. To be consistent with the TopocentricFrame, the convention concerning the azimuth is the same ie azimuth angles are counted clockwise from the local North.

Parameters:

elevation - elevation angle in radian (between -PI/2 and PI/2)

azimuth - azimuth angle in radian (between 0 and 2PI)

range - distance from the origin of the topocentric frame

Method Detail

getElevation

public double getElevation()

Get the elevation angle.

Returns:

elevation angle

getAzimuth

public double getAzimuth()

Get the azimuth angle.

Returns:

azimuth angle

getRange

public double getRange()

Get the range.

Returns:

the range

getPosition

public Vector3D getPosition()

Gets the position.

Specified by:

getPosition in interface Position

Returns:

the position vector.

toString

public String toString()

Produces the following String representation of the topocentric coordinates : (elevation, azimuth, range).

Overrides:

toString in class Object

Returns:

string representation of this position
