Constructor Detail

CardanMountPV

public CardanMountPV(double xAngle,
                     double yAngle,
                     double range,
                     double xAngleRate,
                     double yAngleRate,
                     double rangeRate)

Build cardan mounting.

Parameters:

xAngle - angle of rotation around the local North axis counted clockwise from the zenith and expressed in radian (between -PI and PI)

yAngle - angle of rotation around y' axis (image of the West axis by the previous rotation) counted clockwise from the y' axis and expressed in radian (between -PI/2 and PI/2)

range - distance from the origin of the topocentric frame

xAngleRate - angle rate of rotation around x axis in rad/s

yAngleRate - angle rate of rotation around y' axis (image of y axis by the previous rotation) in rad/s

rangeRate - range rate in m/s

Method Detail

getXangle

public double getXangle()

getRange

public double getRange()

Get the range.

Returns:

the range.

getXangleRate

public double getXangleRate()

Get the angle rate of the rotation around the North axis.

Returns:

the x angle rate.

getYangleRate

public double getYangleRate()

Get the angle rate of the rotation around y' axis (which is the image of the West axis by the first rotation around the North axis).

Returns:

the y angle rate.

getRangeRate

public double getRangeRate()

Get the range rate.

Returns:

the range rate.

getCardanMountPosition

public CardanMountPosition getCardanMountPosition()

Get the Cardan mount position.

Returns:

the Cardan mount position.

getPosition

toString

public String toString()

Produces the following String representation of the Topocentric coordinates : (x angle, y angle, range, x angle rate, y angle rate, range rate).

Overrides:

toString in class Object

Returns:

string representation of this position/velocity
